We take spaces from raw concrete to fully operational — and then run them. Construction, development, and hospitality, all under one roof in Tokyo.
Most firms hand off the project when construction wraps. We don't.
ROCAS is a Tokyo-based group that covers the full lifecycle — from sourcing and structural work through to pouring drinks and running the venue on opening night. We work with developers, international entrepreneurs, and investors who want a single trusted partner, not a rotating cast of subcontractors.
If you're opening (or closing) in Tokyo, we've probably done it before.
Work with usFlooring, electrical, structural metalwork, HVAC, and bespoke wall finishes — all in-house.
Site sourcing, feasibility studies, full fit-outs, and property conversions across Tokyo.
Seamless opening day move-in logistics and strict end-of-lease bare-concrete demolitions.
We don't just build venues — we manage them from concept to nightly service.
From intricate parquet to Bankyo raised subfloors engineered for soundproofing and thermal insulation. We handle prep and install end to end.
Precision-applied textured vinyls, full-wall murals, and accent paneling with zero seams. We make the walls do the talking.

In-house welding and fabrication for heavy structural modifications, custom equipment mounting, and steel stud framing.
Commercial extraction systems and heavy exterior ducting — laid out for hospitality environments where airflow matters.

Delivering speed, strict Tokyo compliance, and zero outsourcing across every phase of your property's life, and back again.
