The Origin

Yashima in Takamatsu-shi, Kagawa, is a plateau resembling a roof. It is famous for its wonderful view from mountaintop and battlefield of Genpei war in ancient times. Though our company was founded in Osaka, the founder Kiyoshi Kawanishi named his company after Yashima, known as symbol of his hometown where he was born.

Description of Business

At our own factory in Kagawa prefecture, we manufacture various car care products from container molding to blending and filling. Japanese Industrial Standards (JIS) certification and ISO 9001 have been acquired, and we undertake OEM manufacturing as well as manufacture our own brand products.

In addition, we utilize our experience gained in automotive products to produce cooling water for power generation facilities that vary in scale.
