Message from the President

Yamaco was started with a monkey wrench work tool in 1946. Now that we are approaching
our 80th anniversary,
as the third president, I think we are capable of creating things under the name
Yamaco that currently do not exist in the world.They should also be products that will be loved for a long time.
We are continuously tackling this challenge,and teamwork and technological strength are essential for that!
We also value the Kaizen activities that we have been conducting for nearly 30 years and hold Kaizen presentations twice a year.
Recently, we presented a forged frying pan at the 97th Tokyo International Gift Show Spring 2024 and successfully won the Grand Prix.
It is an excellent product produced through a project that lasted six years.
We will continue to strive to create B-to-C products that are loved by as many people as possible through the wonders of forging.
Yamaco pursues manufacturing every day with “manufacturing products that currently do not exist in the world” in mind.
We aim to engage in manufacturing that contributes to society by always tackling new challenges and discovering what we can do only by forging.
