President's message

Since our founding in 1956, we have built our business on marine buoys and location information services.
The development of Radio buoys for fishing was the first in the world, and contributed to the efficiency of fishing for tuna and salmon trout fishing vessels using wireless location information.
After that, we also developed Satellite buoys, and the needs for fish school information and oceanographic information are increasing.

On the other hand, Aids to Navigation are also a business foundation, and we supply them to port construction, fishing ports, aquaculture businesses, etc.
From now on, we will also respond to needs for safe navigation around offshore Wind power generation facilities.
We aim to provide the best total solution, from design to equipment selection proposals, installation, and aftercare.
Taking over the venture spirit from the time of our founding, we would like to be a company that cares about our customers and provides safe and environmentally friendly products and information services that are useful to society.
We sincerely ask for your continued support and patronage.

The President and Representative Director
Shuichiro Kimura
