Birth of Mitutoyo Manufacture Aiming for domestic production of micrometers
In 1934, micrometers, which at that time were almost 100% imported,
The founder, Ehan Numata, began efforts toward domestic production.
This is Mitutoyo's first step.
In 1936, the company name was changed to Mitutoyo Manufacture. In the same year, we finally completed the first mass production lot of 100 pieces.
Only 17 pieces are left in perfect condition, and the others are buried on the factory grounds.
This is an expression of our determination not to compromise on quality and performance by making inspections too easy.
It was meant to galvanize the hearts of all employees.
