Ball-bearing research began in March 1918 at the Nishizono ironworks in Kuwana, Mie prefecture, at a time when Japan imported nearly all of its bearings from Europe. Bearings are a capital-goods business — precision heat treatment, precision grinding — and a provincial workshop could not carry the equipment and the sales network at once. In May 1923 the ironworks tied up with the trading house Tomoe Shokai and began selling domestically made bearings under a three-letter mark, NTN, taken from the initials of Niwa Noboru, Tomoe and Nishizono. Manufacturing and selling belonged to different companies from the start; that division of labour was how a latecomer got into a market the Europeans held.
The bearing arm was incorporated separately in 1927, became a joint-stock company in 1934, and was renamed Toyo Bearing Manufacturing in 1937. War work took it to more than 1,500 employees and Japan’s largest bearing maker, and in 1939 it opened the Kuwana plant that has been the physical centre of the company ever since — flattened by bombing just before the surrender, held under reparations designation until April 1952, and still, in 2025, the site chosen to consolidate the metres-wide bearings built for wind turbines.
In May 1949 the company listed on the first sections of the Osaka and Tokyo exchanges — early for a Japanese bearing maker — and put the proceeds into capacity for the reconstruction boom. Through the 1960s it absorbed other bearing makers into a national plant network, and then went abroad ahead of its peers: a European sales company in Germany in 1962, on SKF’s home ground; an American one in New York in 1963; and in 1971 its first overseas plant, in Schiller Park, Illinois, followed by German production the same year. In a business of heavy, low-value-per-kilo standard parts, making them near the customer is the only real defence against freight and exchange rates.
