RWB

RWB (RAUH‑Welt BEGRIFF) is the workshop and brand founded by Akira Nakai, known worldwide for custom, hand‑built widebody conversions on air‑cooled Porsche 911s. The shop has a strong cult following among tuning and Porsche enthusiasts.

The workshop is located in suburban Kashiwa, Chiba Prefecture; the official company page lists the street address and contact details (rwb.jp). Visits are possible but the site is primarily an active garage and brand headquarters rather than a regular public museum.

A working custom shop focusing on one‑off widebody Porsche builds. Expect to see completed RWB cars, fender fabrication, branded merchandise and a compact industrial garage environment.

Look out for:

• Nakai’s signature massively flared fenders and hand‑finished bodywork.

• Air‑cooled Porsche 911s at various stages of conversion.

• Workshop tools, fabricated parts and RWB apparel/branding.

• A compact suburban garage setting rather than a showroom.

Best way to experience it: Check the official site for contact information and confirm any visit in advance. Treat the space as an active workshop—ask permission before photographing or approaching cars and staff, and expect limited public access or formal tours.

• The official company page lists the street address and a contact phone number (rwb.jp).

• This is an active workshop in suburban Kashiwa, not a regular public exhibit.

• Visits may be informal or by appointment; do not assume walk‑in access.

• Always ask before photographing cars or entering work areas.
