About the Brand

THE STORY

Bangkok — the JAH GUIDE logo across the back of a tee, in a beachside shack
Bangkok — where it started

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 archive era. Between 1998 and 2008 the label reached Thai television, magazines, 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.

On the name. "RUB A DUB", "JAH GUIDE" and "DUB" derive from reggae and DUB sound-system culture. They are used throughout this site as references to Jamaican music culture — not to anything else.

Street. Sound. Craft.

The name is a sound.

RUB A DUB is the name Jamaica gave to a dancehall reggae style. One riddim, stripped down by an engineer working the mixing desk like an instrument, rebuilt again and again into new versions — echo and space folded into the mix. That's DUB. Deejays voiced over those versions while the crowd danced close, the style changing shape night after night: that was RUB A DUB. Deejays would also trade the mic back and forth over a single riddim, trading lines on the spot — that heat was part of it too.

The same rhythm, a different face every time it plays. We chose this name because that spirit matches our own: staying ourselves while riding the riddim of the moment, cutting our own version again and again.

What we carry forward is the memory of music, and the craft honed in a sewing factory. RUB A DUB TOKYO wears both, and keeps moving.
