青山産業研究所 Company Profile

With a spirit of reviewing the old and learning the new, all employees unite as one, taking pride and joy in contributing to society.

Since the 8th year of the Taisho era, we have been dedicated to the production of "kohaze." It is said that whether one can beautifully wear a kimono, which is Japan's traditional attire, is determined by the feet. Once you put on tabi (traditional Japanese socks), the "kohaze" is never seen, but for that reason, we strive daily to ensure that it can seamlessly become a part of everyone’s body, taking pride in our manufacturing of "kohaze." We continue to uphold the legacy of our predecessors, who instructed us to "never let it die out, and continue with creativity and ingenuity," maintaining the highest quality and production volume in Japan, and we work hard every day. Additionally, based on our manufacturing techniques for "kohaze," we also produce precision pressed products with complex shapes. Since the 6th year of the Heisei era, we have been focusing on the planning and development of environmentally friendly products such as "eco-resin," "eco-materials," and "chrome-free" components for rubber products and telecommunications-related parts, aiming to develop products that are gentle on the global environment and continue to grow as a manufacturing company that contributes to society.
