Since 1933Our company was founded in 1933, where my grandfather started manufacturing for the military. In the company&#39s long history, there were many times of financial difficulties, due to the reliance on the management system. In a time where the production shifted to overseas. In order to rebuild the system within the company, we had to listen to the customer&#39s voice, and try to solve their problems. The final product we came up with was the Tsutsushita socks, made with confidence that it does what we set out to do, to solve problems.
