TOKYO KEIKI's Development
Since its founding, the TOKYO KEIKI Group has continued to address societal issues. Our history has been a trajectory of taking on challenges relentlessly, which is in our DNA.
Company founder Yoshihira Wada: father of the "measuring instrument"
TOKYO KEIKI's founder Yoshihira Wada was driven by the desire to
create products that would be useful in the nation's development. This
desire led him to found Wada Keiki Seisakusho, Japan's first measuring
instrument factory. He worked on the research and development of
measuring instruments and contributed to the development of
Japan’s measuring instrument industry. At the time, Wada came up
with the Japanese word keiki, taking a hint from the English
expression "measuring instrument." Today, the word is in wide general
use.
Founding to the 1940s:
Promotion of domestic production as a pioneer in nautical instruments
From the time the company was founded in 1896, it promoted the
domestic production of nautical instruments, for which Japan had been
relying on imports. Beginning with magnetic compasses, the company has
since continued to develop and supply gyrocompasses, the gyropilots
that were the forerunners of today's autopilots, and other products.
Further, the company engaged in original development of aeronautic
instruments and instruments for submarines as well.
1950s to 1970s:
Expansion of core technologies and contribution to the development of
Japan’s key industries
The company began manufacturing hydraulic devices in the 1950s. This
contributed to the development of Japan's key industries. In 1963,
TOKYO KEIKI succeeded in practical application of the world's first
ultrasonic flow meter. The company subsequently expanded its
technology, including the development of products that utilized
ultrasound technology, and electronic application devices for use in
aircraft, and grew into a general manufacturer of precision
instruments.
1980s to the present:
Taking on the challenge of resolving social issues through niche-top
business
Efforts were also invested in inertial sensor technology that applied
and further developed gyro technology, as well as microwave
technology. By combining core technologies, we have been able to
develop products that have taken the top shares in diverse niche
markets, including shipping, aviation, railroad, disaster prevention,
agriculture, and energy, thereby supporting the foundation of safe and
secure society and daily living.

Management Targets by 2030
We have formulated 3-year medium-term business plans as medium-to
long-term strategies to realize TOKYO KEIKI Vision 2030. In the 3 years
from FY2021, in addition to strengthening the foundations of our existing
businesses, we worked to identify, incorporate and develop growth drivers.
The 3-year period from FY2024 is the phase of "leap toward growth" in
order to transform us into a stage where we can achieve sustainable growth
and increase corporate value over the medium to long term.
Medium-term Business Plan Basic Policy
For this new phase, in order to shift to a stage where we aim for sustainable growth and medium- to long-term enhancement of enterprise value, we have modified our basic policies to focus not only on expanding sales but also on expanding profits. In addition, another of our basic policies will be to bolster the foundation for improving profit margins and expanding sales.
