Company introduction

The history of our company dates back to 1905 when Sumizo Utsuki opened a repair shop of marine chronometer in Tokyo. Since 1965, we have continued marine business as a manufacturer of measuring system and accumulated our own technical know-how responsive to clients’ needs in the dock industry, sea-transportation industry, and offshore engineering.

Currently, our head office and factory are located in Yokohama. With our original Pressure Type Level Gauge, Inclinometers and other electric devices, we specialize in remote/automatic control of various equipment on vessels and also venturing to new lines of business such as monitoring of various structures’ liquid level and inclination.
