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 grown solely focused on "kohaze." It is said that whether one can beautifully wear a kimono, which is Japan's traditional attire, is determined by what is at the feet. Once you put on tabi (traditional Japanese socks), "kohaze" will never be seen, but for that reason, we strive daily to ensure that it can become a part of everyone's body without any discomfort. We take pride in our manufacturing of "kohaze," adhering to the instructions passed down from our predecessors to "never let it die out, and continue with creativity and ingenuity." We maintain the highest quality and production volume in Japan and continue to improve every day. Additionally, based on the manufacturing technology of "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 kind to the global environment and continue to grow as a manufacturing company that contributes to society.
