IINUMA GAUGE MANUFACTURING is 65th anniversary in 2016.

A small factory located at the foot of Tokyo Tower
moved to the foot of Mt. Yatsugatake with only 6 persons.
And IINUUMA GAUGE became a equipment maker that orders comes from all over the world.

Small factories supported "MONOZUKURI" in Japan.

IINUMA GAUGE MANUFACTURING was founded in 1951.
Founder Sadahachi Iinuma who was specialist for lathe worker built a factory in Shiba, Minato-ku, Tokyo.
In the beginning, we were mainly making gauges to measure the finished dimensions of parts.
This is the origin of the conmapny name.
As Japanese economy recovered due to the special demand of Korean war and manufacturing industry regains momentum, measurement instruments such as gauge also had a lot of demand.
That was before the construction of the Tokyo Tower.
In the area of Shiba, Minato-ku, there were a lot of family-run factories, including our company.
In the 1950s, Japan's manufacturing achieved remarkable growth with the recovery of Japan after the war,
that was supported by the small factories.
