About the Brand
THE STORY
The brand was born
to keep the factory
line moving.
Born in Shimokitazawa, Tokyo in 1970. Raised in Bangkok, Thailand from 1972. Katsuji Sakai spent over 40 years in Bangkok, deep in the world of OEM apparel production.
"When there was downtime at the factory, I didn't want the workers sitting idle. That's how JAH GUIDE began."
In 1996, Sakai founded a 60-person sewing factory in Bangkok. In the gaps between orders, he started a brand — a laboratory for difficult stitching and new forms. When he opened at Bangkok's LUMPINEE Night Bazaar, the brand spread naturally, reaching Thai and international media, DJs, and stylists.
The brand went dormant as OEM work expanded. Answering calls from long-time customers, Sakai brought it back in May 2026 with the exhibition "DUB MEDITATION DUB" — and set up his own company in Tokyo, Rub a Dub Co., Ltd., to carry it forward.
