A practical guide to planning a renovation in Tokyo — cost, timeline, and what to expect.
Start by defining scope, budget, and timeline before you contact contractors. Walk through the space and note what has to change versus what you'd simply like to change — that distinction alone can shift your budget significantly. A clear written brief up front, even a rough one, prevents costly scope changes once work is underway, and it gives every contractor you talk to the same information to quote against.
Costs vary widely by scope, property type, and finish level — a partial refresh costs a fraction of a full gut renovation with structural changes. Material grade (standard, premium, or luxury) is usually the single biggest swing factor. Use our cost calculators for a ballpark figure specific to your project, then request a formal quote once you're ready to move forward.
Most projects run anywhere from a couple of weeks to a few months from start to handover, depending on scope, permitting, and material lead times. Custom or imported materials can add several weeks on their own, so it's worth confirming lead times early if you have a fixed move-in or opening date.
Certain structural changes, commercial fit-outs, and exterior work require permits or building-management approval in Tokyo — requirements vary by ward and by building type (rental mansion vs. owned house vs. commercial lease). We handle this as part of project management, including coordinating with landlords or management companies where needed.
Look for a contractor with in-house trades rather than fully subcontracted crews — it usually means better quality control and fewer scheduling gaps. Ask for a clear written quote before work begins, confirm you'll have a single point of contact for the full project, and check whether they handle permits and final walkthroughs as part of the service.
Expect some noise, dust containment, and temporary disruption to the space — a good contractor minimizes this with proper containment and a realistic day-by-day schedule. Regular check-ins (even brief ones) help catch small issues before they become expensive changes, and a final walkthrough before handover should be standard, not optional.
