Tokyo two-bed new builds: is 50 days really the market pace?

[sailsAndQuill]

I’ve been looking at Tokyo two-bed new-build flats priced from ¥69,160,000 to ¥103,700,000. The active listings suggest they need roughly 50 days to find a buyer.

The outliers mostly seem connected with property tax, but I’m not convinced the live listings are giving a fair picture. Would recent completed sales show the same pace, or am I overweighting homes that remain online precisely because they have not sold? Seasonality may also be involved, although agents have given me conflicting explanations.

The active sample has survivor bias, so I would not treat 50 days as the typical selling period yet. The quicker sales disappear while difficult listings accumulate. You need the original listing dates and outcomes for a fixed group: sold, still available or withdrawn.

Also, how tightly have you drawn the area? A Tokyo-wide figure can blend neighbourhoods with very different buyer pools. Even shifting a boundary slightly may change the result if the sample is modest.

I’d be cautious about attributing the outliers to property tax. Price, exact location, condition at handover and seller motivation could all be moving together. Unless the tax difference is the only meaningful distinction, it may simply be the most visible explanation rather than the decisive one.

Do you have the price history? A flat shown at 50 days may have spent 40 days at an unrealistic price and only 10 at the level buyers accepted. That tells a different story from a correctly priced listing taking 50 days without a reduction.

Buyer financing can blur the timing as well. “Found a buyer” might mean an offer was accepted, financing was settled, or the deal completed. Make sure the completed-sale timeline and the listing timeline use comparable endpoints.

There is another condition issue with new builds: are all of these actually at the same stage? A completed unit available now is not directly comparable with one marketed earlier in the process. I would separate those groups before comparing days, even if both are described as new-build flats.

A simple cohort table would help: listing date, neighbourhood, asking-price changes, current status and final outcome where known. Group listings by the month they first appeared rather than taking one snapshot of what remains online. Withdrawals should stay visible instead of being silently treated as sales or deleted observations.

I disagree slightly that completed deals automatically give the better answer. They are useful, but they may describe an earlier market by the time completion is visible. Current listings show today’s competition. The sensible approach is to use both and be explicit about the lag.

 

[musicAndGate]

For the seasonal question, compare new-listing volume as well as time on market. Fifty days can mean weak demand, but it can also occur while a burst of fresh stock gives buyers more choice. Looking at only the remaining inventory cannot separate those possibilities.

 

[SimpleLane]

Seller motivation is the other missing piece. A withdrawn flat may represent a seller refusing the available price rather than a property nobody wanted. If several units vanished without a completed sale, counting only successful transactions would make the market look faster and more liquid than it was.

 

[lena.voss]

Putting the points together, I’d present 50 days as the age of the current sample, not yet as Tokyo’s normal selling time. The next useful comparison is a fixed cohort within the same neighbourhood boundaries and build stage, with price cuts and withdrawals retained. If its completed sales cluster near 50 days, the estimate gains support; if the quick ones sold and the slow ones remain, the live-listing figure is overstated.
