Harmony with nature from sleep


Preserving the natural colors of plants and animals. The black dots on the unbleached fabric are broken cotton husks. Not bleaching or dyeing the material reduces the impact on water resources and the atmosphere.

A passion for making feather quilts that has been passed down from generation to generation.

Iwata was founded in the first year of Tenpo, over 190 years ago. It all started when we opened a store on Sanjo Street in Kyoto as [Iwata Fudanten]. The third generation, Ichibei Iwata, learned that feather quilts were being used in Europe and thought that ``feathers might be the next material after cotton.''

Iwata is a pioneer of down comforters in Japan, having started researching feathers since the Taisho era.
