In 1934 Yehan Numata (born in current Shiwa-cho, Higashi-Hiroshima-shi) founded a research laboratory in Musashi Shinden, Tokyo, and the Kamata Factory in 1936 in Kamata, Tokyo, naming it Mitutoyo Manufacture (currently Mitutoyo Corporation). In 1937 the company succeeded in the mass production of micrometers for the first time in Japan and has continued improvement and development ever since. Today, as a global brand, our micrometers and diverse lineup of other precision measuring instruments are widely used around the world.
James Watt’s Table-top micrometer (replica)
In 1772, James Watt – known for his invention of the steam engine – invented the first screw device for measuring distance. This device’s U-shaped frame for holding objects to be measured became the standard design for the modern micrometer. The product on display is a replica.
M110-25
A micrometer that inherits a form that closely resembles Mitutoyo’s first generation product. This form is still widely used today.

“MDH-25MJ”
A digimatic micrometer that made measurements in the 0.0001mm range possible for the first time in the world. Mitutoyo’s innovative “0.1μm resolution ABS (absolute) rotary encoder” and “high accuracy screw machining technology” reduces instrumental errors to ±0.5μm.
