Nissei

What Nissei does

Nissei Co., Ltd. is a Japanese manufacturer-trading company (メーカー機能を持つ商社) founded in November 1946 in Osaka by Daishiro Ogura, now led by Representative Director and President Sadaohiko Ogura of the founding family. The company operates with a dual business model combining material procurement and authorized distribution of major industrial material brands with proprietary in-house processing capabilities. It serves enterprise customers across multiple industrial sectors including aerospace, sporting goods, semiconductor manufacturing, railway infrastructure, food packaging, and consumer goods. Nissei maintains 8 locations — 4 in Japan (Osaka headquarters, Tokyo branch, Oita Factory, Kobe Factory) and 4 overseas in Singapore, Hong Kong, Dongguan, and Weihai, China — and employs 184 people as of March 2026.

The company's core capabilities center on high-performance fiber materials, with proprietary technologies in prepreg manufacturing, filament winding (FW), slit processing, and non-woven fabric processing. Its product portfolio spans carbon fiber intermediate materials (UD tape, multi-axis fabrics), CFRP composite products, composite rolls, FRP railway railings, industrial tape materials, non-woven fabrics (including Sontara and Nisselon brands), polishing pads for semiconductor manufacturing, ceramic sintered products, and the Sequel CF high-pressure air cylinders used in air breathing apparatus. Nissei holds a one-third stake in the Sakai Composite joint venture (established 1977 with Toray and Sakai Sangyo) for processing Torayca carbon fiber, and distributes a wide range of authorized Toray brand materials including Lumirror films, Toyolac ABS resins, Torelina PPS resins, Lycra fibers, Ecsaine/Ultrasuede artificial leather, and Promilan 66 nylon.

Nissei generates revenue through synthetic fiber and carbon fiber product sales, processing services (slit, non-woven, prepreg, FW), original proprietary product sales (Sequel CF cylinders, composite rolls, FRP railroad barriers, Nisselon ceramic products), and authorized distribution of third-party materials. For FY ending March 2026, the company reported net sales of ¥23,743 million and operating income of ¥634 million, equating to an operating margin of approximately 2.7%. The go-to-market model is direct enterprise field sales from Japan offices and Asia-Pacific sales network, with quote-based pricing on B2B industrial contracts, no public price list, and customer inquiries handled via website forms. The company maintains ISO 9001 (quality) and ISO 14001 (environmental) certifications at its domestic manufacturing sites. In March 2026, Nissei initiated a voluntary recall of its Sequel CF NS683A 6.8L high-pressure air cylinder model manufactured between February 2019 and June 2024, introducing a product quality risk to its flagship proprietary line.
