Problems
Does any of this sound familiar?
Every one of these is something we set out to solve.
No way to tell how far the work should go
The tenant does not speak Japanese at the walk-through
One small job, three different trades to book
Extra work appears behind the wall, and starts before you agree
Our Way
How wework
Quality of finish, and knowing where things stand at any point.We keep the work running that way on purpose.
- 01
If extra work is needed, we ask before we start
There is always something you only find once the wall comes off. When extra work is needed, we send you the photos and wait for your decision before starting.
- 02
If the schedule may slip, we say so at the time
If it looks like we may not finish as planned, you hear it then — not at the last minute — and we rework the schedule with you. We do not carry on quietly.
- 03
We are still here after handover
If something bothers you after the work is done, we come back and put it right. That is why so many of the property managers and owners we work with stay with us.
- 04
We can work across languages
Starting with our president, we speak English, Tagalog and Japanese directly, and other languages through translation where needed. We take on the conversations that tend to go wrong over language, like who pays for what.
SERVICES
From a vacated unitto one you can rent again
Wallpaper and flooring, swapping fixtures, carpentry, electrical work through partners, full strip-out for offices — you do not need to find a different contractor for each trade. We take on jobs from a single room or a single spot.
SYSTEM
We built the system soyou never wait for an update

Extra work — your call
We found damage to the substrate. Please check the photos and let us know whether to proceed.
Photos from site, how far the work has got, a question about extra work. What owners actually want to know is always the same: where does it stand right now? So that nobody has to dig through phone calls and email threads, we built our own business app, anken.ai, and we use it on real jobs, every day.
anken.ai puts jobs, schedules, estimates, invoices and orders in one place. We build it ourselves — the same people who run the jobs — so anything awkward to use, we can fix. We are also making it available to other contractors and property managers with the same problem. If that interests you, say so in the chat.

Interior materials are not arriving: the lead-time problem that followed the price rises (August 2026)
The July price revisions went ahead, and nearly every interior materials maker has now announced one. But what is actually holding up work on site is not the price — it is getting hold of the goods. One maker has suspended new orders for adhesive. Crude oil keeps swinging up and down, so there is no sign of prices coming back down either.
Project
A stain under the fridge: overlaying 5 mm poly plywood, half a day and about 12,000 yen
We moved the fridge and found a stain underneath it. Replacing the whole base board would have cost far more, so we laid a 5 mm melamine-faced plywood over the existing one. Half a day, a few thousand yen in materials.

When will interior material prices settle? Four reasons, seen from the site (August 2026)
The weak yen, expensive oil, the Middle East. Plenty of reasons get listed, but from site the order of importance looks different. Our own reading of the 2026 price rises.

Why are interior contractor websites full of illustrations? Four reasons the photos never appear
Put the websites of restoration and interior firms side by side and you see the same soft illustrations of people, in much the same form. Here is why we think that happens, and what we did on our own site.

Interior materials up 18-30% (July 2026): what it does to a restoration estimate
In July 2026 the two largest interior material suppliers revised their prices one after the other. Here are the rates, the products covered, and how it actually feeds through to a restoration estimate.

Why the going rate for restoration work is not reliable: three things to check in an estimate
You will not find a table here saying "wallpaper, ¥XX per sqm". Here is why we left it out, and three things worth checking whenever you take an estimate.

Wallpaper paste and floor adhesive are not arriving: the 2026 order suspensions and shipping limits
Wallpaper paste, floor adhesive, sealant. The ancillary materials that never take the lead role have been hit through 2026 by temporary order suspensions and shipment limits. What is behind it, and what it means on site.

The website of OS K.K., a restoration (genjo-kaifuku) contractor in Katsushika, Tokyo, is now live. We will carry on writing about what we went back and forth on while building it, and about what we deliberately left out.
