TB Kawashima Co.

What TB Kawashima Co. does

TB Kawashima Co. (now operating as AUNDE Boshoku Co., Ltd. / アウンデ紡織株式会社) is a Japanese manufacturer of interior fabrics for transportation applications, serving the automotive, railway, aircraft, and entertainment venue industries. The company was established in December 2009 and began operations in July 2010, with headquarters in Aisho-cho, Echi-gun, Shiga Prefecture, Japan, and operates a global production footprint spanning the United States, Mexico, China, Thailand, Indonesia, and India through overseas subsidiaries.

The company's product portfolio centers on three proprietary original materials—BRIN NAUB, Banex, and SILCREVE—combined with seven patented functional chemical treatments covering stain resistance, odor elimination, antistatic, antibacterial, anti-virus, anti-allergen, and dual-action properties. Manufacturing operations are governed by multiple industry certifications including ISO 9001, IATF 16949 (automotive quality), JIS Q 9100 (aerospace), ISO 14001 (environmental), and ISO 45001 (occupational health and safety). Named end-customer applications include Toyota (Estima) and Mazda (Roadster) in automotive, Japan Railways and private rail operators in mass transit, and unspecified aircraft manufacturers.

Revenue is generated through direct B2B sales to OEMs and tier-one suppliers under multi-year supply contracts typical of transportation interior manufacturing. Following the November 2024 acquisition of an 80% equity stake by Germany's AUNDE Achter & Ebels GmbH—with Toyota Boshoku retaining the remaining 20%—the company has been integrated into the AUNDE global network of 29 countries and 116 production plants. The corporate name was changed to AUNDE Boshoku Co., Ltd. and dual representative directors were appointed, signaling a transition from a Toyota-affiliated supplier to a globally integrated Tier 1.5 platform. Total group headcount stands at 693 employees (239 domestic, 454 overseas) as of December 2025.
