ROOTS

昭和13 年、前身の富澤三四郎商店が群馬県にて製綿業として創業。「人間は天然素材の恵みを受けるのが本来の姿である」という理念を持ち、地元群馬・富岡のシルクを生かした布団の製造など、天然繊維の特徴を活かした、安全かつ高機能な寝具を作り続けている。現在は工場内に足利工業大学睡眠科学センターを併設し、産学連携での研究にも取り組んでいる。

In 1938, the company’s predecessor “The Store of Tomisawa Sanshiro” was opened as a cotton business in Gunma Prefecture. With the idea of "humans being inherently meant to be receiving blessings of natural materials" the company continues to make safe and high-performance bedding that takes advantage of characteristics of natural fibers and manufactures futons while making the best use of local Tomioka silk from Gunma. Currently, the Sleep Science Center of the Ashikaga Institute of Technology is located in the factory, so the collaboration between industry and academia is being promoted at the company.
