Gohsyu

What Gohsyu does

Gohsyu is a precision metal forging manufacturer founded in 1946 and headquartered in Konan City, Shiga Prefecture, Japan. The company operates under GOHSYU Holdings Corporation as its ultimate parent and provides precision die-forged components using hot forging (600–4,000 ton presses), warm forging, cold forging (up to ϕ35mm diameter), rotary forming, and proprietary composite hot+cold forging processes. In-house capabilities extend from die design and manufacturing through precision machining (turning, milling, broaching) to heat treatment (quenching, normalizing, FIA) and full quality inspection with 3D scanners, CMM, and SEM equipment. The company holds 23 patents for proprietary forging technologies and is certified to ISO 9001, IATF 16949, and ISO 14001 standards.

Gohsyu's core product portfolio includes helical forged tooth gears, connecting rods, crankshafts, axle shafts, CVT pulleys, parking locks, carrier planetary units, common rails, VGR steering rack bars, cold forged hollow shafts, and medical-grade magnesium alloy pipes. The company serves major Japanese automotive OEMs (Toyota, Honda, Nissan, Mazda, Suzuki, Daihatsu, Mitsubishi) and tier-1 suppliers (Aisin, Denso, JTEKT, JATCO, Musashi Precision), alongside agricultural machinery makers (Kubota, Yanmar), motorcycle OEMs (Yamaha, Kawasaki), industrial robot manufacturers, and medical device companies. Recent product diversification has extended into industrial power transmission (high-efficiency bilateral drive gear speed increaser/reducer developed with Yokohama National University) and consumer products (Sustainability Magnesiumity Green Fork via Makuake crowdfunding).

The business model is B2B direct sales of custom-engineered forged and machined components on a quote basis, with no publicly disclosed pricing. Gohsyu operates a global manufacturing footprint across Japan (Konan City headquarters and Ritto City cold forging facilities), Indonesia (P.T. Sankei Gohsyu Industries / SGI, established 1996, 700 employees), China (Changzhou Gohsyu Automobile Parts / CGA, established 2012), and Mexico (Gohsyu Mexicana / GMX, established 2014, 220 employees), giving it approximately 1,000+ employees worldwide and proximity to Japanese OEM assembly plants in all major regions. The company maintains technology cooperation agreements with forging partners in India, Malaysia, Thailand, Germany, and Vietnam, and pursues technology licensing for international market access.
