What ROKI Co., does
ROKI Co., Ltd. (株式会社ROKI) is a Japanese filtration technology company founded in 1958 as Toyo Filter Mfg. Co., Ltd. and rebranded in 2008, headquartered in Hamamatsu, Shizuoka, Japan. The company employs 1,001-5,000 staff and operates as a privately held corporation under President Shimada Takaya, having transitioned to a holding company structure in 2013.
The company operates two principal business lines. Its core B2B franchise manufactures air cleaners and oil filters for automobiles, motorcycles, and general-purpose engines, supplying global automotive and motorcycle OEMs with what the company characterizes as world-leading air cleaner production volume. Applications extend to F-1 motorsports and aftermarket replacement parts, with wholly-owned manufacturing subsidiaries in the USA, China, India, Thailand, Indonesia, Vietnam, Mexico, Romania, and Korea. The second business is a consumer mask line launched in 2021 under the 纏 (MATOI) brand, including 纏Air and the premium beauty-focused MATOI TONE UP MASK, sold via the unified ROKI公式ストア e-commerce platform, drug stores, supermarkets, and hometown tax donation programs in Japan.
ROKI's R&D platform, anchored by the ROGIC (ROKI Global Innovation Center, opened 2013) and ROKI R&D India (2016), has developed proprietary nanofiber spinning technology (enabling polyimide nonwoven fabrics and water-soluble nanofiber filters co-developed with Keio University), as well as MOF (Metal-Organic Framework) mass-production technology protected by Japanese patents (Nos. 7406668 and 7411846). Revenue is generated primarily through hardware sales to B2B OEM/aftermarket customers globally and B2C mask sales domestically in Japan, with no disclosed revenue figures or external capital raises in the input data.
