Yamacs’ History of Striving for Technological Innovation

Yamacs began its journey as Yamashita Mark Works in a corner of a photo studio in Tanimachi, Osaka in 1945. Now, the company has expanded with fully-equipped plants in Kanto and Kansai, receiving orders from all over the country from companies in many different fields.
But the ambitions the company first had when it was founded have remained unchanged. We are constantly striving for the best technologies and creativity, forever evolving in our efforts to advance together with our clients.
