45R GLOBAL

Ahead of 45R’s 50th anniversary in 2027, our new Ginza Flagship Store opens on September 8, 2026. Across four floors, each level reveals a different expression of 45R: Kuri no Ma 栗の間 on the first floor, built around chestnut and the roots of our storemaking; Kyokumen no Ma 曲面の間 on the second, where curved forms create a softer, more organic space; Ai no Ma 藍の間 on the third, devoted to Japanese indigo, hinoki, and traditional plasterwork; and Chabatei 茶馬亭 on the fourth, a gallery and tea room inspired by sukiya architecture and the culture of tea. Together, these four spaces bring craftsmanship, materials, and the spirit of 45R into one new home in Ginza.

Super Gauze is one of 45R’s signature materials — light, soft, and exceptionally comfortable against the skin. Made from rare Supima organic cotton, it has evolved over the years from a simple T-shirt into the distinctive knit we know today. This journal traces its history, the people and techniques behind it, and the color-making that continues to shape its future.
