Established in 1930 (Showa 5) as a trading company specializing in imports and exports, the year 2020 marks the 90th anniversary of its founding, and we are making every effort to further develop the M.WATANABE Group.

From the mid-1960s, under the policy of selling silicon (Si) related products to the semiconductor industry, we started manufacturing and selling our own products such as quartz processed products, silicone rubber molded products, and cleaning equipment.
As a manufacturing trading company, we have grown along with the growth of the IT society by providing high-quality products and services.

Going forward, we will continue to aim to create a company where employees of each group company, centered on M.WATANABE & CO.,LTD., work vigorously every day and the entire workplace becomes a learning organization.
And, with a strong will to meet the true needs of society, we will continue to push forward with every business every day.

We look forward to your continued support and patronage.
