building the parts that move society.
We forge critical parts for passenger cars, trucks, construction and agricultural machinery, as well as marine fuel-injection components — from raw material to finished part, with short lead times. In-house die making and small-lot orders welcome.

A century of hot-forging expertise combined with integrated production from raw material to finished part. We support your manufacturing with quality, speed, and responsiveness.
Over 100 years of trust
Founded in 1915, with roots as a swordsmith in the Sengoku era. Our long forging heritage has earned lasting customer trust.
Integrated production
From steel procurement and cutting to heating, forging, machining, inspection, and shipping — all in-house, for short lead times and stable quality.
In-house die making
High-precision 3D CAD/CAM design and the latest machining. We respond quickly to spec changes and welcome die-only orders.
Short lead time, small lots
As little as ~4 weeks from meeting to mass production. With our own steel procurement, we handle small lots without waste.
Thorough inspection
Visual inspection with dedicated gauges plus magnetic particle testing for flaws invisible to the eye — supporting safety-critical parts that demand high quality.
Own delivery across Kanto
Delivery on your preferred date with our own vehicles. We also handle urgent and distant requests on a case-by-case basis.
From raw material to finished part, all in-house
Steel ordering and management, cutting, heating, forging, trimming, machining, inspection, and shipping — we handle every step ourselves. This delivers short lead times and low cost, and lets us reflect spec changes quickly.
Because we manage steel procurement ourselves, we can take on small-lot orders without waste.
In-house die design for fast response to your needs
We design and manufacture forging dies entirely in-house. With 3D CAD/CAM design and the latest automated machining, we respond quickly and flexibly to spec changes.
Our craftsmen, who know our hammers inside out, design optimized dies. We also welcome die-only orders — please feel free to consult us.
Own-fleet delivery across the Kanto region
We deliver on your preferred date with our own vehicles, and accommodate urgent and distant requests as needed.
What our customers say
Switching a part from casting to forging eliminated porosity ("su") and stabilized quality.
When we could not draw a forging-ready part drawing, Ogawa Tekko redrew and proposed one for us.
Their forgings machine more easily than other suppliers — feedback we hear from several customers.
