Topman is a Japanese manufacturer of saws, wood carving tools, carpentry tools, knives, tree climbing equipment, and other specialised metal tools. Topman is based in Miki-city, Japan

The Topman story begins with Mr. Eiji Okada, who started business in 1924, producing and supplying tools throughout Japan. He later expanded business to overseas, mainly to China and other East Asian countries in 1931.

As the business expanded, he founded Okada Hardware Company, for further development.

In 1991, Okada Hardware changed their company name from Okada Hardware Company to Topman Company Limited. In 1998 Topman became ISO 9000 certified, the first company to be so certified in the region.
