Garments made to be worn and loved for years — designed, cut and sewn one at a time, by one man in Berlin.

Ever since I was a child, wearing clothes I loved would brighten my heart and make ordinary days feel enjoyable. That is part of why I wanted to make clothes. I want the people who wear what I make to feel the way I felt as a child. Making clothes with that feeling — that is ARAI.

Musuhi

Musuhi is ARAI’s 2026/27 collection, and the work closest to Osamu now. He drew it from the Zen monk Issan Ichinei, who travelled from China to Japan seven hundred years ago and became a central figure in the exchange between the two cultures.

The garments hold a sense of space — mu, emptiness · ku, void · jaku, stillness. For Berlin Fashion Week the collection was presented inside a working tea house rather than on a runway — the pieces worn and seen up close, over cups of Japanese tea. Designed, cut and sewn in Berlin, in cloth chosen bolt by bolt.

collection

Garments, bags and objects — made by hand in Berlin.

A few bodies of work, since 2005. Each piece is cut and sewn one at a time.

in the studio

He chooses the cloth bolt by bolt. Most of what is in the studio now is judo-uniform cloth — sashiko cotton from a mill in Gifu, strong enough to be worn with affection for years.

Every piece is designed, cut and sewn in Berlin — Osamu cuts the patterns and sews each garment himself, in pesticide-free cotton, linen and natural cloth.

about

From a silk-farming house in Gunma to a studio in Berlin.

— Osamu Arai was born in 1982 in Maebashi, Gunma, 100 km north of Tokyo. Gunma made the silk for kimono, and he grew up in Shirasawa in a house of silkworm farmers — close to cloth from the start.

He learned to cut patterns and make garments — in Japan, in Sydney, and finally in Berlin, where he settled in 2011. His own label, ARAI, has shown in Berlin and Gunma since 2005.

He makes his garments to last, and to feel good on an ordinary day. Over the years they quietly become part of the people who wear them.
