Since 2024, Japan specialty chemicals M&A has followed several distinct patterns. Japanese majors, including AGC, Mitsubishi Chemical Group, Kyocera and JSR, have carved out businesses in resins, adhesive raw materials and semiconductor materials, and Japanese chemical makers such as Sumitomo Bakelite, Konishi and Nippon Shokubai have agreed to acquire them. In semiconductor materials, JSR acquired a Kyoto-based maker of high-purity chemicals, and 2 specialists in the Osaka area formed an equity and business alliance. Foreign capital has also been active: a Korean materials group acquired a Japanese flavor and fragrance company, and a US investment firm announced a plan to launch a tender offer for a Japanese electronic materials maker. Japanese chemical makers and chemical trading companies, for their part, have acquired companies with specific products and customers in the US, Europe, Taiwan and China.
This article is written for corporate development and international business development teams at foreign companies that see Japan as an acquisition market, a source of partners, or a source of acquirers for their own businesses. It covers the market structure, the industry landscape, domestic consolidation, inbound transactions (foreign acquirers buying Japanese companies, “Out-In”), outbound transactions (Japanese acquirers buying abroad, “In-Out”), the industry-specific factors acquirers examine, and the implications for overseas acquirers. Older transactions are included where they illustrate the structure of the sector, with their year stated. In this article, specialty chemicals refers to functional chemicals such as semiconductor and electronic materials, functional resins and films, adhesive raw materials and additives (including inks and papermaking chemicals), flavors and food ingredients, and pharmaceutical intermediates and active pharmaceutical ingredients (APIs).
1. Market Structure — Scale of the Chemical Industry and Drivers of Consolidation
Market size
No official statistics isolate specialty chemicals, so we use figures for the chemical industry as a whole. According to the Japan Chemical Industry Association (JCIA), shipments of the chemical industry in calendar 2023 were ¥33.4tn (~USD 223bn; 8.9% of manufacturing) excluding plastic and rubber products, and ¥50.9tn (~USD 339bn; 13.6% of manufacturing) including them. In this broader definition, the chemical industry ranks second among Japan’s manufacturing industries in both shipments and value added. The industry employs about 400,000 people in the narrow definition and about 960,000 in the broad definition. R&D spending in fiscal 2023 was ¥2.57tn (~USD 17bn) in the narrow definition, 18.5% of all manufacturing R&D. In chemical sales for 2023 (excluding pharmaceuticals), as compiled by the American Chemistry Council and cited by JCIA, Japan ranked fourth at USD 155.9bn, after China, the United States and Germany (JCIA, Japan’s Chemical Industry in Graphs 2025).
Japanese companies hold large positions in semiconductor materials. The Ministry of Economy, Trade and Industry (METI) reports that Japanese companies held a 48% global share in 2021 across major semiconductor materials, including wafers, resists, chemical mechanical planarization (CMP) slurries, photomasks, sputtering targets and bonding wires (METI, Semiconductor and Digital Industry Strategy).
Demand segments
Customers, approval processes and sales channels differ widely by segment. In M&A, the segments in which a company holds positions shape both the set of likely acquirers and the way they assess the business.
| Segment | Main products | Business characteristics |
|---|---|---|
| Semiconductor and electronic materials | Photoresists and their raw materials, high-purity chemicals, deposition precursors, CMP slurries, encapsulants, solder resists | Adoption follows qualification in the customer’s manufacturing process. Miniaturization requires higher purity and control of metal impurities |
| Functional resins and films | Polycarbonate sheets, optical sheets, high-performance resins | Grades by application in construction, automotive and electronics. Molding and processing equipment and know-how required |
| Adhesive raw materials and additives | Emulsions, tackifier resins, adhesives and sealants, resin additives, inks, papermaking chemicals | Grades designed around customers’ formulations and processes. Sales through trading companies and distributors drive volume |
| Flavors, food ingredients and pharma-related | Flavors and fragrances, sugar alcohols and other food ingredients, pharmaceutical intermediates and APIs | Production under food and pharmaceutical quality standards. Application proposals tied to customers’ product development |
The segmentation is our own, based on the cases in this article.
Five drivers of consolidation
- Portfolio review at chemical majors — Sumitomo Chemical reorganized into 4 business sectors in October 2024 and is reshaping its business portfolio under its medium-term plan starting in fiscal 2025. Resonac states in its integrated report that it had separated 15 businesses by July 2025 and created more than ¥200bn (~USD 1.3bn) of enterprise value through divestitures. In July 2025, Mitsubishi Chemical Group transferred Mitsubishi Tanabe Pharma to Bain Capital for about ¥510bn (~USD 3.4bn), citing the declining affinity and synergy potential between chemicals and pharmaceuticals. In their divestitures, Mitsubishi Chemical Group described the acquirer as the “best owner,” AGC stated that the transfer was the best option for the business’s growth, and Toray cited allocating resources “from a best-owner perspective” (Sections 3 and 4).
- Concentration on semiconductor and electronic materials — Of Resonac’s revenue of ¥1,347bn (~USD 9.0bn) for FY2025, semiconductor and electronic materials accounted for ¥506bn (~USD 3.4bn; about 38%), and the company aims to raise that share above 50%. ADEKA renamed its Electronic Materials Division the Semiconductor Materials Division in April 2025 and established a semiconductor materials R&D laboratory. In acquiring a Taiwanese process chemicals company, Sumitomo Chemical set a target of roughly doubling its semiconductor process chemicals revenue by fiscal 2030 from fiscal 2024 (Section 5).
- Review of listed subsidiaries and affiliates — In 2022, Kaneka made its listed subsidiary Cemedine a wholly owned subsidiary through a share exchange, citing faster decision-making. In September 2024, Sumitomo Chemical sold part of its shares in its affiliate Sumitomo Bakelite to GIC, the Singapore sovereign wealth fund, reducing its voting stake from 22.62% to 15.61%. In an adjacent field, Fujitsu sold its listed subsidiary Shinko Electric Industries (semiconductor package substrates) in 2025 to a vehicle led by a fund managed by Japan Investment Corporation (JIC), with Dai Nippon Printing and Mitsui Chemicals as minority investors. Parent companies are moving in both directions, taking some listed subsidiaries fully in-house and selling others to new owners.
- Fund involvement — JIC took JSR private in 2024 and Shinko Electric Industries private in 2025. The stated purpose of the JSR take-private was to pursue structural reform and industry consolidation free from short-term earnings pressure. Other fund acquirers include Carlyle (Seiko PMC, 2023), Bain Capital (T&K TOKA, 2024), Polaris Capital Group (B Food Science, 2025) and KKR (planned tender offer for Taiyo Holdings, 2026) (Sections 3 and 4).
- Business succession — Japan’s Small and Medium Enterprise Agency estimated that by 2025 about 2.45 million owners of small and medium-sized enterprises would be over 70, and that about half of them (1.27 million) would have no designated successor (SME Agency, Current Analysis of Business Succession and M&A). Now that 2025 has passed, the agency’s 2026 White Paper reports that the share of companies without a successor is declining, while owners aged 60 or older made up a majority in 2025, and that 67,949 companies closed or dissolved voluntarily in 2025 (SME Agency, 2026 White Paper on Small and Medium Enterprises). In chemicals, companies founded more than 60 years ago are making concrete capital decisions: Yamanaka Hutech, founded in 1960, was sold in full to JSR (Section 3), and Yasuhara Chemical, founded in 1959, was taken private by its founding family and delisted in March 2026.

Japanese companies actively acquiring at home or abroad include Sumitomo Bakelite, Nippon Shokubai, JSR, Osaka Organic Chemical, adhesive maker Konishi and Hodogaya Chemical. Sumitomo Bakelite acquired a business from AGC in 2025 and in 2026 agreed to acquire one from Kyocera, with which it has no capital ties. JSR acquired a semiconductor materials company while its take-private was under way, and after going private sold its emulsion and diagnostics businesses, reshaping its portfolio through both acquisitions and divestitures.
Companies within major groups
Japanese chemical majors and trading houses have long held specialty chemical companies. Since 2024, several have been sold or agreed to be sold outside their groups: E-TEC, established in 1963 as a JSR subsidiary; B Food Science, established in 1969 as a joint venture of Nikken Chemicals and Mitsui & Co.; Soda Aromatic, owned 66% by Toray and 34% by Mitsui & Co.; and the emulsion businesses of Mitsubishi Chemical Group and its subsidiary Japan Coating Resin.
Owner-run manufacturers
Many of Japan’s non-listed chemical makers are owner-run. Yamanaka Hutech (Kyoto; founded 1960), a non-listed maker of high-purity chemicals and deposition precursors for semiconductors, became a wholly owned subsidiary of JSR. In Sanbo Chemical (Sakai; founded 1950), a non-listed contract manufacturer of organic synthesis products, Osaka Organic Chemical acquired shares and now holds 33.8% of the voting rights. Among listed companies, Yasuhara Chemical (Fuchu, Hiroshima; founded 1959), a maker of terpene resins, saw a tender offer by a company wholly owned by its president, Teiji Yasuhara of the founding family, succeed in December 2025, and the company was delisted on March 6, 2026 following a share consolidation. Capital decisions vary: sale to a third party, a minority investment, or a founding-family take-private. Non-listed companies disclose limited information, and identifying them requires research beyond public databases.
Concentration in Kansai
Of the companies covered in this article, Kaneka, Daicel, Nippon Shokubai, Osaka Organic Chemical and Konishi are headquartered in Osaka City, Sanbo Chemical in Sakai, and Yamanaka Hutech in Kyoto. Sumitomo Chemical and Nippon Paint Holdings have dual headquarters in Tokyo and Osaka. The following listed mid-size makers are also headquartered in Kansai.
| Company | Headquarters | Consolidated revenue (FY2026/3) | Main products |
|---|---|---|---|
| Sumitomo Seika Chemicals | Harima, Hyogo (head-office functions in Osaka) | ¥148bn (~USD 989mn) | Superabsorbent polymers, gases, fine chemicals |
| Sanyo Chemical Industries | Kyoto | ¥128bn (~USD 852mn) | Surfactants and other functional chemicals |
| Osaka Soda | Osaka | ¥100bn (~USD 666mn) | Basic and functional chemicals |
| DKS (Dai-ichi Kogyo Seiyaku) | Kyoto | ¥83bn (~USD 552mn) | Surfactants and other industrial chemicals |
| Arakawa Chemical Industries | Osaka | ¥82bn (~USD 547mn) | Papermaking chemicals, resins |
| Sakai Chemical Industry | Sakai | ¥81bn (~USD 543mn) | Inorganic chemicals |
| Fuso Chemical | Osaka | ¥77bn (~USD 513mn) | Fruit acids, ultra-high-purity colloidal silica |
| Stella Chemifa | Osaka | ¥37bn (~USD 245mn) | High-purity fluorides |
3. Domestic Consolidation (In-In) — Carve-Outs From Majors and Acquisitions of Non-Listed Specialists
Case 1: Sumitomo Bakelite and AGC (2025) — A major carves out its polycarbonate business
In July 2025, AGC announced an agreement to transfer the polycarbonate business of AGC and its subsidiary AGC Polycarbonate (Chita, Aichi) to Sumitomo Bakelite. The business covers products for construction and for industrial and electronics applications, including the Twincarbo polycarbonate sheet line and optical sheet materials. AGC explained that it had reviewed the business for asset efficiency, growth and carbon efficiency under its medium-term plan, and concluded that transferring it to Sumitomo Bakelite, with its strong technology and ability to make effective use of AGC’s assets, was the best option for the business’s growth.
Sumitomo Bakelite states in its annual securities report that it took over the business in October 2025 and is integrating it to strengthen its products for construction and for industrial and electronics applications. It funded the acquisition from its strategic investment budget. The price was not disclosed.
This transaction shows that (i) a chemical major, after a business review, transferred a resin business to a specialist in the same field, and (ii) the seller cited the acquirer’s technology and its ability to use the seller’s assets as the basis for its decision.
Case 2: Sumitomo Bakelite and Kyocera (2026, scheduled for October) — Semiconductor encapsulants from a major with no capital ties to the acquirer
In January 2026, Sumitomo Bakelite announced that it would acquire part of Kyocera’s chemical business: epoxy molding compounds for semiconductor encapsulation, die-attach pastes for semiconductors, and industrial resins. Kyocera transferred the business to a new company (Kawasaki) through a company split in July 2026, and Sumitomo Bakelite is scheduled to acquire all of the new company’s shares in October 2026. The consideration is ¥30bn (~USD 200mn), subject to price adjustment, about 1.3x the business’s revenue of ¥23.2bn (~USD 155mn) for FY2025/3. The 2 companies had no capital or personnel ties.
Sumitomo Bakelite cited strengthening its presence in information and communications technology and its technology for high value-added products, and capturing growth markets such as AI data centers. In October 2026, it also announced capacity expansions for advanced semiconductor encapsulants in Suzhou, China, and in Singapore.
This transaction shows that (i) following Case 1, the same acquirer is buying a business from another major, this time one with which it had no capital ties, (ii) the seller moved the business into a new company through a company split and is selling the shares, and (iii) the acquirer’s purpose is to add technology and customers in a field where it already operates.
Case 3: Konishi and Mitsubishi Chemical Group (2026, scheduled for December) — An adhesive maker acquires an emulsion business
In February 2026, Konishi (Osaka), the maker of Bond adhesives, announced an agreement to acquire the acrylic emulsion and synthetic resin emulsion businesses of Mitsubishi Chemical and its wholly owned subsidiary Japan Coating Resin. The businesses will be transferred to a new company through a company split, and the share transfer is scheduled for December 1, 2026. Japan Coating Resin’s total revenue for FY2025/3 was about ¥12.2bn (~USD 81mn). The price was not disclosed.
Konishi cited strengthening its adhesives business under its medium-term plan and combining it with its trading functions, and obtaining technology and sales channels in the acrylic emulsion market, where its own presence is limited. Mitsubishi Chemical Group explained that, following a portfolio review under its medium-term plan, it concluded that operating the business under the best owner would support its sustainable growth.
This transaction shows that (i) a downstream user, an adhesive maker, is acquiring a chemical major’s raw-material business, and (ii) the acquirer’s purpose is to obtain technology and channels in a product area where its presence was limited.
Case 4: Nippon Shokubai and JSR (2025) — A post-take-private divestiture and emulsion polymerization technology
In November 2024, Nippon Shokubai agreed to acquire all shares of JSR’s subsidiary E-TEC (Yokkaichi, Mie; established 1963) for ¥7.2bn (~USD 48mn), subject to price adjustment, and completed the acquisition on April 1, 2025. E-TEC makes construction, civil engineering and industrial materials based on synthetic rubber latex and acrylic emulsions, and had non-consolidated revenue of ¥13.3bn (~USD 89mn) for FY2024/3. Nippon Shokubai cited a broader range of construction chemicals, stronger emulsion polymerization technology and production capacity, and better proposals to customers through formulation technology.
In October 2025, JSR also sold its diagnostics and diagnostic materials business to Tokuyama for ¥82bn (~USD 547mn). JSR, which went private in June 2024, has acquired a semiconductor materials company (Case 5) while divesting other businesses.
This transaction shows that (i) a major taken private is divesting peripheral businesses to Japanese chemical makers while concentrating on semiconductor materials, and (ii) the acquirer cited manufacturing technology (emulsion polymerization) and capacity, not only products, as reasons for the acquisition.
Case 5: JSR and Yamanaka Hutech (2024) — A Kyoto maker of high-purity semiconductor chemicals
In May 2024, JSR agreed to acquire all shares of Yamanaka Hutech (Kyoto; founded 1960), and completed the acquisition on August 1, 2024. Yamanaka Hutech is a non-listed specialist in high-purity chemicals for semiconductors and in precursors for chemical vapor deposition (CVD) and atomic layer deposition (ALD). The price was not disclosed.
JSR stated that the acquisition adds deposition materials, which are growing in importance for advanced devices, to a portfolio centered on photoresists. It plans to combine Yamanaka Hutech’s record of more than 60 years of supply to leading-edge customers with JSR’s R&D, quality control and supply chain.
This transaction shows that (i) a semiconductor materials maker acquired 100% of a non-listed specialist to broaden its product range, and (ii) the acquirer cited the target’s long supply record with leading-edge customers.
Case 6: Osaka Organic Chemical and Sanbo Chemical (2026) — An equity and business alliance between Kansai specialists
In June 2026, Osaka Organic Chemical acquired shares in Sanbo Chemical (Sakai) and now holds 33.8% of the voting rights. Sanbo Chemical is a non-listed contract manufacturer of organic synthesis products with plants in Sakai, Wakayama, Shizuoka (Iwata) and Saga, 170 employees, and revenue of about ¥6.1bn (~USD 41mn) for the fiscal year ended August 2024. It targets revenue of ¥10bn (~USD 67mn) by the fiscal year ending August 2032.
The alliance covers integrated design of raw materials for semiconductor photoresists (monomers, photosensitizers and solvents), joint development, and cooperation on purification and metal-impurity control, and the companies expect to complement each other in their shared markets of semiconductors and displays. They intend to use the difference between Osaka Organic Chemical’s focus on liquids and Sanbo Chemical’s on powders to improve purification and quality control. In 2021, Osaka Organic Chemical had also acquired Mitsubishi Chemical’s acrylic resin business for hair cosmetics.
This transaction shows that (i) the parties chose a minority investment with a business alliance rather than a full sale, and (ii) specialists working in different product forms are combining their technologies to serve the same markets in semiconductors and displays.
Case 7: Polaris Capital Group and B Food Science (2025) — A trading-house subsidiary sold to a fund
In January 2025, Polaris Capital Group agreed to acquire, through a subsidiary, all shares of B Food Science (Chita, Aichi), a wholly owned subsidiary of Mitsui & Co., and B Food Science came under the group’s ownership later that year. B Food Science was established in 1969 as a joint venture of Nikken Chemicals and Mitsui & Co. It manufactures functional food ingredients, mainly sugar alcohols, and pharmaceutical and chemical raw materials, and provides contract manufacturing. Mitsui & Co. described the sale as part of rebuilding its business portfolio. The price was not disclosed.
This transaction shows that the buyer of a functional materials maker held by a trading house was a domestic fund rather than a strategic, and that funds are among the buyers of subsidiaries that Japanese groups decide to sell.
4. Foreign Capital in Japanese Specialty Chemicals (Out-In)
For overseas companies, the cases below are examples of entry into Japan’s specialty chemicals sector through acquisition. The targets fall into 2 groups: subsidiaries and businesses of Japanese groups (Cases 8, 10 and 12) and listed companies (Cases 9 and 11).
Case 8: Samyang group and Soda Aromatic (2026) — A Korean materials group acquires a flavor and fragrance company from 2 Japanese groups
In July 2026, the Japanese subsidiary of Korea’s Samyang group acquired all shares of Soda Aromatic (Tokyo; founded 1915), which had been owned 66% by Toray and 34% by Mitsui & Co. The enterprise value was ¥41bn (~USD 273mn). Toray explained that it was allocating resources from a best-owner perspective and improving capital efficiency, and expected an after-tax gain of about ¥8bn (~USD 53mn). Mitsui & Co. sold its stake as part of its portfolio restructuring. Samyang cited expanding from basic materials into flavors and specialty chemicals, and synergies with its sugar-reduction and dietary fiber businesses.
This transaction shows that (i) the buyer of a company jointly held by 2 Japanese majors was an overseas materials group, and (ii) the buyer’s purpose was to combine the target’s products and technology with its own businesses.
Case 9: KKR and Taiyo Holdings (2026, tender offer not yet launched) — A foreign fund’s acquisition with a Japanese strategic investing and the founder’s relatives reinvesting
In March 2026, KKR announced a plan to launch a tender offer at ¥4,750 per share for Taiyo Holdings, whose main products are solder resists, protective materials for printed circuit boards. Taiyo Holdings has stated that it will support the tender offer once launched while leaving the decision to tender to shareholders. Among the major shareholders, DIC (20.19%) and Kowa (6.35%), the asset management company of the founder’s relatives, will not tender; instead, both will sell all of their shares to Taiyo Holdings in a share buyback after a share consolidation. The investment firm Oasis (15.6%) will tender. Kowa plans to reinvest part of its proceeds (about ¥11bn, ~USD 73mn) in preferred shares of the acquirer’s parent, and Sekisui Chemical plans to invest about ¥31.9bn (~USD 213mn) for a 10.0% stake in the holding company.
KKR cited growing demand for electronic materials driven by generative AI, data centers and communications infrastructure. Sekisui Chemical cited complementarity with its electronics business. On October 9, 2026, Taiyo Holdings announced that, because competition law procedures in China and investment control procedures in Japan remained outstanding, it was moving the target launch of the tender offer to late November.
This transaction shows that (i) a Japanese strategic is joining a foreign fund’s acquisition as a new minority investor, (ii) the exit of a chemical major (DIC) and a sale and reinvestment by the asset management company of the founder’s relatives are combined in a single transaction, and (iii) in this case, regulatory procedures in multiple jurisdictions are shaping the timetable.
Case 10: Carlyle and Seiko PMC (2023) — A chemical major’s listed subsidiary sold to a foreign fund
In 2023, Carlyle acquired Seiko PMC, a listed subsidiary of DIC, through a tender offer at ¥1,070 per share, a premium of 90.05%. The tender offer ran from September 4 to October 17, 2023. DIC did not tender its 54.51% stake; instead, Seiko PMC was to buy back DIC’s shares after a share consolidation, under a structure designed so that DIC’s after-tax proceeds would equal those from tendering. Seiko PMC makes papermaking chemicals, resins for printing inks, functional monomers (through KJ Chemicals) and cellulose and chitin nanofibers. Carlyle stated that it would support the company’s overseas expansion and new businesses as a high-performance resin chemical maker competing globally, and that going private would speed up decision-making. DIC described the sale as part of a portfolio review begun at the end of 2022.
This transaction shows that (i) a foreign fund acquired a Japanese major’s listed subsidiary, and (ii) the structure was designed around the selling parent’s after-tax proceeds.
Case 11: Bain Capital and T&K TOKA (2024) — A take-private of a listed ink maker
In 2024, Bain Capital acquired T&K TOKA, a maker of printing inks including UV-curable inks, through a tender offer at ¥1,410 per share, raised from ¥1,400. The tender offer ran from January 23 to March 6, 2024, and Bain Capital acquired 90.99% before squeezing out the remaining shareholders. Funds affiliated with Dalton, an activist investor holding about 24.6%, had agreed to tender.
This transaction shows that (i) foreign funds are buyers of listed mid-size chemical makers, and (ii) an activist shareholder holding about a quarter of the shares agreed to tender.
Case 12: Sika and Hamatite (2021) — A Swiss group acquires a Japanese tire maker’s adhesives and sealants business
In 2021, Swiss construction chemicals and industrial adhesives group Sika acquired Hamatite, the adhesives and sealants business of Yokohama Rubber, with revenue of about CHF 160mn and 5 plants in Japan and abroad. The deal was announced on April 28, 2021 and completed on November 1, 2021. Yokohama Rubber explained that it would concentrate on its tire and other core businesses under its medium-term plan, and that the adhesives business would grow better under a global leader. The price was not disclosed.
This transaction shows that (i) a Japanese group’s non-core chemical business was sold to a foreign strategic in the same field, and (ii) the seller presented the sale as a way to secure the business’s growth.
5. Japanese Specialty Chemicals Makers Abroad (In-Out)
For overseas companies, Japanese chemical makers are potential acquirers of their businesses and potential partners. Their recent transactions show what they buy, on what criteria and at what price levels.
Case 13: Nippon Paint Holdings and AOC (completed March 2025) — A fund-owned resin formulator
In October 2024, Nippon Paint Holdings announced the acquisition of all interests in the holding company of AOC, a Tennessee-based formulator and manufacturer of resins such as unsaturated polyesters and vinyl esters for coatings, adhesives, sealants and composites, from investment fund Lone Star. It completed the acquisition on March 3, 2025. Enterprise value was USD 4.35bn (~¥653bn), about 8.2x AOC’s 2023 EBITDA. AOC’s 2023 revenue was USD 1,496mn and EBITDA USD 528mn, a margin of 35.3%. The acquisition was funded with cash on hand and borrowings, without issuing new shares. Nippon Paint cited AOC’s leading position in North America, customized products, customer service grounded in a deep understanding of customers’ businesses and strong technical service, and strong cash generation supported by low capital requirements.
Nippon Paint’s stated acquisition criteria are (a) earnings per share (EPS) accretion from the first year without relying on synergies, (b) a high-quality business with low business risk, (c) strong management, and (d) room for further value creation within the group. In its Q&A session, the company stated that it does not limit targets by field, region or size; that it avoids capital-intensive businesses and businesses that swing sharply with market conditions; that it maintains the autonomy of local management; and that it approached the seller before the fund launched a sale process.
This transaction shows that (i) a coatings major expanded into specialty chemicals adjacent to paint, (ii) a strategic acquirer provided the exit for a fund-owned business, and (iii) the acquirer disclosed its criteria and the price level (about 8.2x EV/EBITDA).
Case 14: Hodogaya Chemical and Framochem (completed August 2026) — A long-time European competitor
In March 2026, Hodogaya Chemical announced the acquisition of all shares of Framochem (Hungary; established 1992), owned by US-based VanDeMark, for about EUR 87mn (about ¥16bn, ~USD 107mn), and completed the acquisition in August 2026. Framochem manufactures phosgene-based APIs, intermediates and fine chemicals, with FY2024 revenue of about ¥9.0bn (~USD 60mn) and operating profit of about ¥1.9bn (~USD 13mn). The share price paid is about 8x that operating profit and about 1.8x revenue. Hodogaya Chemical explained that, as part of the specialty chemicals growth strategy in its new medium-term plan, it aims to secure a direct manufacturing base in Europe while maintaining exports from Japan, and noted that Framochem had long been a competitor.
This transaction shows that (i) a Japanese mid-size maker acquired an overseas competitor working with the same chemistry, and (ii) the purpose was a manufacturing base close to demand rather than additional products.
Case 15: Sumitomo Chemical and Asia Union Electronic Chemical (announced 2025) — A Taiwanese semiconductor process chemicals company
In November 2025, Sumitomo Chemical announced an agreement to acquire all shares of Asia Union Electronic Chemical (Taipei; established 1998; about 200 employees), a semiconductor process chemicals company with plants in Kaohsiung and in Nevada, US. Completion is subject to regulatory approvals and other procedures. The price was not disclosed. Sumitomo Chemical stated that the acquisition gives this business its first base in Taiwan and its second in the US, and targets roughly doubling its semiconductor process chemicals revenue by fiscal 2030 from fiscal 2024.
In March 2025, chemical trading company Nagase & Co. agreed to acquire the Asian high-purity semiconductor chemicals business of US-based SACHEM, including operations in Japan, China and Korea, for about USD 101mn, and completed the acquisition in June 2025. Nagase cited strengthening its position as a semiconductor materials maker and bringing in SACHEM’s technology for recovering and regenerating tetramethylammonium hydroxide (TMAH) developer as an environmental solution.
These transactions show that (i) a Japanese chemical maker and a chemical trading company are acquiring local companies where semiconductors are manufactured, and (ii) Sumitomo Chemical tied its purpose to a revenue target in a specific product field, while Nagase framed its purpose around recovery and regeneration technology.
Case 16: Mitsui Chemicals and Ultradent Products (completed August 2026) — A founder-owned US dental materials maker
In June 2026, Mitsui Chemicals announced the acquisition of Ultradent Products (Utah; founded 1978), a dental materials maker in which the founder was a major shareholder, for USD 900mn, and completed the acquisition on August 14, 2026. Ultradent’s 2025 revenue was USD 372.1mn and operating profit USD 30.9mn; the consideration is about 2.4x revenue. Mitsui Chemicals cited gaining leading products in whitening and restoratives and a direct sales base in the US, complementing its German subsidiary Kulzer, and expects annual synergies of more than USD 40mn by fiscal 2030. After the acquisition, it is moving the global headquarters functions of its oral care business to the US, and Ultradent’s CEO will also serve as CEO of Kulzer.
This is not a chemicals transaction as such, but a materials business developed by a chemical maker. It shows that (i) a Japanese chemical major acquired a founder-owned company, and (ii) it entrusted the target’s management with running the combined business.
In April 2025, Kuraray also announced the acquisition of US-based Nelumbo. Nelumbo has surface modification technology for water repellency without fluorine compounds, and the deal is an example of an acquisition aimed at a specific technology.
6. Industry-Specific Factors Examined by Acquirers
In Japan specialty chemicals M&A, acquirers examine industry-specific factors in addition to financials. Based on the reasons and synergies disclosed by the acquirers in the cases above, these factors fall into 3 groups.
- Products and technology — Which customers’ processes and products the company’s materials are qualified for, and how long that record goes back. The acquirer in Case 5 cited the target’s more than 60 years of supply to leading-edge customers. In semiconductor materials, purification and metal-impurity control were the purpose of an alliance (Case 6). Emulsion polymerization and formulation technology (Case 4) and fluorine-free surface modification technology (Kuraray) were also acquired.
- Customers and channels — Customer mix and complementarity with the acquirer’s products and channels. The acquirer in Case 3 sought technology and channels in a market where its presence was limited. The acquirer in Case 16 sought a direct sales base in the US, and the acquirer in Case 8 cited synergies with its food ingredients business. The acquirer in Case 13 valued customized products and technical service grounded in an understanding of customers’ businesses.
- Production and footprint — Plant locations, proximity to demand and capital requirements. The acquirers in Cases 14 and 15 sought manufacturing bases close to demand. The acquirer in Case 13 valued low capital requirements and strong cash generation, and stated that it avoids capital-intensive businesses.
7. Implications for Overseas Acquirers
Target universe
In Japan specialty chemicals M&A, the targets in these cases fall into 3 groups: subsidiaries and businesses of Japanese groups, including chemical majors and trading houses (Cases 1 to 4, 7, 8, 10 and 12); listed companies (Cases 9 and 11); and non-listed specialists (Cases 5 and 6). Japanese chemical makers were the buyers in most carve-outs, while a foreign strategic (Case 8) and a foreign fund (Case 10) also acquired subsidiaries of Japanese groups. Identifying non-listed specialists requires research beyond public databases, and approaching them and parent companies typically involves direct contact in Japanese.
Transaction structures
The cases show several structures: carve-outs in which the seller first moves the business into a new company through a company split and then sells the shares (Cases 2 and 3); minority investments with a business alliance (Case 6); tender offers for listed subsidiaries in which the parent’s stake is bought back after a share consolidation so that its after-tax proceeds equal those from tendering (Case 10); and fund acquisitions in which a Japanese strategic invests and the founder’s relatives reinvest (Case 9). Regulatory procedures can extend timetables: JSR’s tender offer was postponed from the originally planned December 2023 to March 2024 pending regulatory approvals, and the launch of the Taiyo Holdings tender offer has been moved back (Case 9).
What sellers emphasize
Parent-company sellers publicly framed their decisions around the business’s future: AGC stated that the transfer to Sumitomo Bakelite was the best option for the business’s growth, Mitsubishi Chemical Group referred to the best owner, Toray to a best-owner perspective, and Yokohama Rubber stated that the business would grow better under a global leader. Sellers also paid attention to after-tax proceeds, as the structure in Case 10 shows. In our view, acquirers in Japan are well served by presenting a plan for the business’s growth alongside the price.
