We handle a variety of products and materials, starting with rubber, resin, and machined parts.
We accurately integrate the needs of our users with the technologies and products of our partner manufacturers to solve the challenges faced by our users. We offer machining processes such as cutting, which shapes materials by removing excess material, and extrusion molding, where materials placed in pressure-resistant molds are processed by applying high pressure and forcing them through a small gap to create a uniform cross-sectional shape.

Company information
Our company has obtained the Japanese Industrial Standards (JIS) certification for both of our domestic factories.

We strive to be a customer-oriented company that continuously advances to solve our customers' problems and various development needs with our unique rubber compounding and manufacturing technologies, driven by our commitment to completion. [History] Tasaki Asahi was founded in 1949 (Showa 24) during the chaotic period shortly after the end of World War II as "Tasaki Meriyasu Seisakusho." In 1970 (Showa 45), we established "Asahi O-Ring Co., Ltd." focusing on the functionality of vulcanized rubber. Subsequently, in 1973 (Showa 48), we began full-scale manufacturing and sales of rubber sealing materials under the current name "Tasaki Asahi Co., Ltd."
