Utilizing advanced technology employed for 140 years since the company's founding, we have developed products that incorporate "silk".

Primarily composed of the same protein as human skin, silk possesses excellent moisture retention and humidity control properties, providing comfort as a naturally derived material.

Our products undergo various evaluation tests, proving twice as effective in deodorizing as other materials like polyester, ensuring a consistently pleasant experience.

In collaboration with a national university, we utilize advanced technology to produce tree essential oil with richer functional ingredients in Hokkaido, Japan.

With consideration for the natural bounty of Hokkaido, we also engage in forestry to nurture nature as an integral part of our business.

The brand was born in the natural environment surrounded by the mountains of Japan.

The products are made using natural materials from Chichibu Town, where the forest accounts for 87%.
