YANAGISAWA CO.

What YANAGISAWA CO. does

YANAGISAWA CO., LTD. (株式会社ヤナギサワ) is a privately held Japanese precision machining company founded in 1938 and headquartered in Fukaya City, Saitama Prefecture. The company specializes in CNC lathe precision turning of difficult-to-cut materials (難削材), including stainless steel grades (SUS303, SUS304, SUS316L, SUS440C, SUS630), Inconel 600 nickel-based superalloy, titanium alloys, aluminum, and brass. It produces components for automotive parts manufacturers (engine, steering, drivetrain, fuel injection, and transmission systems) and industrial equipment OEMs serving agricultural machinery, construction equipment, and trucks. Key customers include Bosch, Denso, NSK Steering Systems, Nachi-Fujikoshi, and Kyosan Electric.

The company operates three manufacturing sites: the Fukaya Factory (primary Japan site, ~6,600 tsubo) and Ranzan Factory (~5,000 tsubo) in Saitama, Japan, plus Yanagisawa Precision (Thailand) Co., Ltd., a wholly-owned subsidiary in Chonburi Province established in 2011 with 18,000 tsubo of land. Combined equipment includes 142 NC lathe machines in Japan and 51 in Thailand, supported by robotic work-feeding systems for high-volume runs. Technical capabilities include machining from Ø6 to Ø100 mm diameter workpieces, surface finishes to Rz0.6, and dimensional tolerances to 0.001mm for Ø7–Ø18 mm parts. Certifications include ISO9001:2015 and ISO14001:2015 (Japan); Thailand operations hold ISO9001:2008 and ISO/TS16949:2009.

Revenue is generated via B2B contract manufacturing with quote-based pricing negotiated per order against material, complexity, volume, and delivery requirements; long-term supply agreements govern the enterprise automotive customer base. A small direct-to-consumer channel exists through a BASE e-commerce shop and Amazon.co.jp, selling a proprietary G-Zero cap accessory for Goal Zero LED lanterns. Go-to-market relies on direct enterprise sales, regional B2B matchmaking events (Saitama Business Arena), and trade show participation. Registered capital is ¥39.6 million; the company has remained independent since 1996, when Tokyo SME Investment (東京中小企業投資育成) took a minority stake.
