About the NTN Name

The name NTN was created as a trademark by combining the ‘N’ from Noboru NIWA, a man who raised capital for the business and became the company’s first president, Jiro NISHIZONO, the firm’s top engineer, and ‘T’ from the Tomoe Trading Co., which sold the company’s products, all of which carried the NTN mark.
The company’s name was changed to NTN Mfg. Co., Ltd. and later to Toyo Bearing Mfg. Co., Ltd. (Toyo means “the Orient,” a broader area than Japan.)
Today, we are, of course, NTN Corporation.
Upon the last name change in 1989 we applied a new meaning to NTN — “For New Technology Network” (Networking The World With New Technology) — to indicate a shift in focus from the historical meaning to a forward-looking vision.
