During the Edo period (1603-1867) in Japan, many clockmakers and craftsmen were flourishing in the Nagoya region where the most powerful lords at the time took direct controls.Being a depot for good-quality wood also helped Nagoya to boost its clock manufacturing industry.
Aichi Tokei Denki became the first joint-stock company in the industry and realized growth by focusing on exports to overseas markets. It boasted advanced technologies in clock making,as represented by the winning of the best prize in a clock accuracy competition for eight years in a row from 1951

The technologies we nurtured in clock making further evolved in aircraft manufacturing. We utilized our adhesion and processing techniques in wood processing to produce wooden propellers that were commonly used in aircrafts at the time.The Atsuta engine we developed and produced with the technical guidance of Daimler-Benz boasted the performance of high speed cruising. Our unique ideas impressed the world, such as the invention of folding wings, like a grasshopper, that enabled aircraft to be stored in small spaces. We were also involved in making the first prototype of a domestic automobile.We own technological capabilities, creativity, and a hearty appetite for new challenges. This spirit continues to live on in our corporate culture today.

When the war ended, a large expanse of devastated fields stretched throughout the land of Japan. The wartime fires also destroyed our factory. Aichi Tokei Denki, however, soon overcame the devastation and started focusing on improving the infrastructure for reconstruction. We applied our technologies that we built from previous experience to producing meters for water, gas and automobiles as well as to producing machining tools. The passion for contributing to society, which was engraved in the course of postwar reconstruction, remains ingrained in our management philosophies.

Utilizing the know-how and experience we gained through clock making and aircraft making, we made dramatic progress in elaborating water and gas meters. Being in Japan, prone to natural disasters such as earthquakes and tsunamis, we were driven to develop microprocessor-based gas meters and waterproof technologies.Our efforts in improving energy-saving technologies to supplement the lack of resources eventually bore fruit. We succeeded in developing the world's first electromagnetic flow meter that runs for ten years on batteries. Furthermore, we introduced innovations in designing compact, lightweight and space-saving products to better accommodate them in small spaces.We made tremendous progress and established ourselves as a top manufacturer in Japan.

Our products elaborated and perfected by tireless challenges were naturally accepted by the world.
Our business is now expanding internationally.
We strive to contribute to improve infrastructure in emerging countriesby
providing measuring solutions to mixed issues ranging from medical problems to energy issues that exist in various fields.
