60 years in business

60 Years in Business

Dear valued customers and partners,

Rubycon Corporation celebrates its 60th anniversary at Apr. 2012, with sincere thanks to your patronage and assistance to our products and services.

Company was founded in April 1952 as Nippon Denkai Seisakusho Co., Ltd. by Teruo Tonouchi the current chairman with merely 8 employees. It was still in the period of confusion after the war, and there were a lot of difficulties to overcome in building the firm basis of business, as many people in the same age experienced back then.
Now, 60 years since then, we have a total of 14 factories and 22 sales offices with over 3000 employees worldwide.

We desire continuing to be a Company that strives to manufacture having dreams and passion just like inception, and that can contribute to all of you.

April 2012

Teruo Tonouchi
Chairman & CEO
Shuichi Katsuyama
