In 19015, the late Shuchi Yamamoto founded YAMAMOTO IRON WORKS in small town of Tojo in Hiroshima Prefecture. During the year 1926, the engineers from Germany visited the company to teach the heat treatment techniques. And the production of Pneumatic Rock Drills started.

The company's trade name changed to YAMAMOTO ROCK MACHINE in 1996. Yamamoto Rock Machine Co., Ltd had opened its firsts official oversea representative office in Ho Chi Minh City, Vietnam in 2010
