What Achilles does

Achilles Corporation (アキレス株式会社, TYO:5142) is a Tokyo-headquartered, publicly listed diversified polymer materials manufacturer founded in 1947. The company operates eight business segments organized by application: construction/civil engineering (rigid polyurethane insulation boards, Tn-p tunnel void filling method, EPS lightweight fill, TR Panel wall system, Juten Bag void repair); manufacturing/equipment (films, rubberized fabrics, urethane foams under the Achilles Airron brand, RIM molding); electrical/electronics (ESD prevention products, ST-Poly conductive coating technology, wafer carriers and chuck tape for semiconductor fabs); automotive (Cabron synthetic leather, PVC leather, laminate products); agriculture (greenhouse films, biodegradable mulch); medical/disaster prevention (inflatable air tents including NP-45 negative pressure tent, LCT-400 rescue boat, Dokodemo Ouchi Bed shelter bed); living/leisure (Freabell mattresses, boats); and footwear (Shunsoku children's athletic shoes with 84+ million cumulative pairs, Achilles Sorbo leather shoes, exclusive Japan distribution of BROOKS running shoes).

The underlying technology base centers on advanced polymer engineering - polyurethane foams, PVC films and sheets, synthetic leather, and rubberized fabrics - supported by proprietary processes including polypyrrole-based ST-Poly conductive coating and the Tn-p foamed polyurethane injection method with 25+ years of implementation history. The company generates revenue primarily through B2B sales of industrial materials to construction, semiconductor/electronics, automotive, and agriculture sectors via dedicated product department contacts, plus B2C sales of consumer footwear through retail shoe stores, the Achilles Webshop e-commerce site, and exclusive Japan distribution of international brands. Notable operational metrics include 1,001-5,000 employees, production facilities in Japan (Ashikaga, Yamagata), the US (Washington State since 1973), China, and Taiwan (recycling ~10,000 wafer transport cases monthly), and a tenfold contamination reduction achievement for a major semiconductor customer's wafer spacers. Subsidiaries span insurance agency services (Achilles Shouji), trading, and advanced technology products. In April 2025, Achilles acquired InfoControl under Bridgepoint PE backing, signaling a strategic extension into digital data services alongside its traditional materials business.
