The Alfalfa Valve and the Angle Valve became widely used across the country as designated models. This marked the start of the agricultural water business.

The story behind the invention of the
ASAHI AV resin valve

Our efforts produced results. The resin valve was recognized as a product that solved problems with metal valves. Today, it is finding application in many different areas.

As a pioneer in resin valves, and with the evolution of phenol resin polymerization and synthesis technologies, we contributed to development of the automobile and building machinery industries.

2013In 2013, we added Drico Ltd. to the ASAHI YUKIZAI Group.

In the area of natural resources, Drico is engaged in the development of geothermal power resources throughout Japan. In well drilling, Drico takes pride in being number one in Japan in the numbers of hot spring wells drilled and cumulative well depth, and is one of the top Japanese company in the area of well drilling.
