Which ward of Kawasaki has the most tower condominiums? Not Nakahara (Musashikosugi), but Saiwai, west of Kawasaki Station (2026 list by ward)

Units: Japanese statistics express prices in 万円 (units of ¥10,000) and often use the tsubo (about 3.31 m²) as a unit of area. In this article, ¥5.48 million per tsubo corresponds to 548万円 in the Japanese original.

Ask about “tower condominiums in Kawasaki” and most people think of Musashikosugi. But when we counted every condominium of 20 floors or more in Kawasaki, building by building, the ward with the most was not Nakahara but Saiwai, which spreads out west of Kawasaki Station.

Which ward of Kawasaki has the most tower condominiums?

Counting buildings of 20 floors or more, Saiwai Ward has the most with 20, and Nakahara Ward has 16. Kawasaki as a whole has 49 (completed buildings, as of October 2026).

Saiwai’s 20 include one UR (Urban Renaissance Agency) rental building, Urbane Bio Kawasaki. Counting only condominiums sold to owners, Saiwai still has 19, more than Nakahara.

How many floors does a building need to be a tower condominium?

There is no legal definition. This article uses the threshold common in industry statistics: 20 floors or more above ground.

Some 20-floor buildings are long, slab-shaped blocks rather than towers, but we counted them regardless of shape. If you want to compare slender, tall towers, the 30+ and 40+ columns are a better guide.

Why, then, is Musashikosugi called “the tower condominium town”?

Because slender high-rise towers are packed closely around the station. Of the 11 buildings in Kawasaki with 40 floors or more, 9 are in Musashikosugi.

Saiwai’s towers are spread across the west side of Kawasaki Station, Shin-Kawasaki, Tode and Yako, and 9 of them have 20 to 22 floors.

How different are closed prices for towers around Musashikosugi and Kawasaki Station?

Over the most recent year, the average closed price was about ¥5.48 million per tsubo (about ¥1.66 million per m²) around Musashikosugi Station, and about ¥4.34 million per tsubo (about ¥1.31 million per m²) around Kawasaki Station.

A year earlier (2024), the averages were about ¥4.46 million per tsubo (about ¥1.35 million per m²) around Musashikosugi Station and about ¥4.28 million per tsubo (about ¥1.29 million per m²) around Kawasaki Station, so the gap widened sharply over the year.

We compiled transactions from the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) contract price data (April 2025 to March 2026) in districts (町) where tower condominiums stand, for buildings with the same year of construction as those towers. Some sales in low- and mid-rise buildings in the same district and of the same year are included.

Are more tower condominiums on the way?

Ten residential towers of 20 floors or more are under construction or planned, including three in Musashikosugi due for completion between 2027 and 2029.

If all are completed as planned, Saiwai will have 21 and Nakahara 19, so the ranking by number of buildings will not change. The size and timing of planned projects may change.

How we counted

• Scope: residential buildings in Kawasaki with 20 or more floors above ground, completed as of October 2026. Both owner-occupied and rental buildings are included, regardless of shape (tower or slab).
• Counting: where a development has several buildings on one site, we counted only those with 20 floors or more, one by one (for example, of the nine residential buildings in Park City Shin-Kawasaki, only the two 30-floor buildings are counted).

Note: The counts and lists in this article are based on our own research using publicly available information, and we cannot guarantee that every building is included. If you notice an omission or error, please let us know through our contact form. Closed prices were compiled and processed by us using the contract price data (API) of the MLIT Real Estate Information Library. This service uses the API of the MLIT Real Estate Information Library, but the currency, accuracy and completeness of the information provided are not guaranteed.
