What’s Seiken?
The Seiken Brand
-
Soon after our founding in 1937, we established Seidouki Kenkyujo (Brake Laboratory). In the following year, we successfully began domestic production of brake rubber cups and brake fluid.
In 1959, Seidouki Kenkyujo (Brake Laboratory) became an independent company, leading to the establishment of Seiken Chemical Industry Co., Ltd. The company supplies brake parts and brake fluid to automobile manufacturers as OEM products, while also providing aftermarket products developed to meet the same level of quality.
As a distributor, we play an important role in promoting high-quality, high-performance Seiken brake parts and brake fluid both in Japan and internationally.
