50th anniversary page

We were able to celebrate our 55th anniversary thanks to your support.
Since our foundation, we have been developing, manufacturing, and selling level meters, automatic control equipment, and various sensing equipment. We could continue our business for 55 years thanks to patronage toward us by our customers and other people related.
In this occasion, we would like to say hearty thanks to all of you supported, and ask your further support and patronage toward us in the future.

55th anniversary logo

We have created our "55th anniversary logo" with our mind of thankful to customers and all of people supported us.
The logo is based on Yamaden symbol color blue, and designed characters of "55."
By combining the cutting edge technologies and long cultured know-how, we will challenge to create valuable products welcomed by our customers. We will make full effort for "developing unique products" that match our customers' needs in various fields.
