Aisen Industrial Official

アイセン・インダストリアル株式会社

Our story

Founded in 1946, Aisen Co., Ltd. initially specialized in the production of palm-based Tawashi brushes under the Aisen brand. We have always been driven by the desire to create innovative products that add value to daily life. With a focus on safety, product usability, and sustainability, we continue to develop new materials and manufacturing techniques that meet the evolving needs of consumers worldwide.

The household goods industry in Kainan City has long been a key production hub for cleaning tools, especially those related to water use. Originally known as the palm industry, it produced a variety of goods such as ropes, brooms, and Tawashi brushes.

It is believed that Kobo Daishi (Kukai), the monk who established Koya-san (Mt. Koya), now a UNESCO World Heritage Site, brought back and planted palm trees after his study trip to China around 1,200 years ago.

Our strategies

・Possible to propose household wares that focus on time-saving and efficiency (Japanese patented material) for cleaning.
・e.g. trepica which are 0.045 (mm) ultra-fine brushes penetrate invisible fine grooves and scratches and remove the dirt with light force.
・Possible to directly export a product from China because we have several partner factories in China.
・Possible to take an OEM order as an original brand.
