The 3LDK ward

Koto is the ward of Toyosu, Kiba and Kameido. Its most traded home is a 70 m² 3LDK, not a studio, and about 37% of condo sales are family-sized, one of the highest shares among the 23 wards. The median 3LDK sold for about ¥64M. Population grew 5.5% between 2020 and 2025, third among the wards, and households grew 12%.

Prices rising faster than before

Condo prices per m² rose about 7% a year over the past five years, faster than the five years before. At about ¥1.2M per m² Koto is a little above the Tokyo average. Benchmark residential land rose 11.5% in the past year.

Station distance matters a lot

Condos within 5 minutes of a station sell for about 26% more per m² than those 11–15 minutes away, one of the biggest gaps in Tokyo. Toyosu, Monzen-Nakacho and Kiyosumi-Shirakawa are the priciest stations at about ¥1.2–1.3M per m². Minami-Sunamachi, often 12 minutes or more from the station, is the cheapest at about ¥750k.

Big earthquake and flood exposure

Koto has the third highest earthquake probability of the 23 wards: about 82% for 6-lower or stronger in 30 years, and about 30% for 6-upper. Much of it is reclaimed land. 93% of benchmark sites are in the worst-case flood zone, and almost half in zones of 3 m or deeper, mainly in the low eastern areas around Kameido and Ojima. Newer towers on the bay are built higher, but check the hazard map for each address.

Renewal

Part of Koto's waterfront is in the Central Tokyo and Waterfront renewal area, which is why Toyosu and Ariake keep adding towers. Vacancy is the lowest of the 23 wards.

Median price per m² by yearHouses are the better deal on space — A m² of house floor space costs about 38% less than a m² of condo, even though the house price includes land. If you need room more than convenience, a house buys considerably more space. That gap has widened over the decade as condo prices pulled ahead.

Price per m² by building age (2021–2025 sales)How condos age here — In recent sales, condos lose about a quarter of their per-m² value by around 20 years old and half by around 39. Prices keep falling by roughly 2% a year even after 25 years, so older condos here are cheap for a reason. Check the repair fund and rebuild plans.Houses bottom out at around 26 years — House prices per m² drop about 42% from new by age 26, then flatten, because by then buyers are mostly paying for the land. A house older than that costs little more than its plot, a good option if you plan to renovate or rebuild.

Condo price per m² by construction periodBuilding age matters less than location — Over the last decade, pre-1981 condos have appreciated at about the same pace as 2000s buildings (around 4.9% a year), so in this market location matters more than building age. Pre-1981 buildings, built before the current earthquake standard, trade about 15% below 1980s–90s buildings.

About this data

Figures are medians of real transactions reported to Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) through its quarterly price survey. House prices per m² divide the total price (land and building) by the floor area. Medians based on fewer than 20 sales are not shown. The latest quarters are preliminary and are revised as more survey responses arrive.
