On May 7th, Tokyo Kantei unveiled the findings of its survey on the resale value (RV) of ten-year-old condominiums in the Greater Tokyo Area (GTA) for 2023.
The survey focused on condominiums aged 9 to 11 years listed in the company's database that were sold as second-hand units in 2023, comparing their initial brand-new sale prices with their resale prices.
The GTA consists of Tokyo, Kanagawa, Chiba and Saitama prefectures.
In the GTA, the survey identified 445 stations where RV could be calculated, with an average RV value of 139.5%.
100% denotes the price per tsubo when brand new, meaning the GTA saw an average capital gain of 39.5% over the past ten years in condos measured.

These properties were sold during a period of market recovery following the Great East Japan Earthquake, resulting in relatively lower initial sale prices.
Out of the 445 stations surveyed, RV exceeded 100% at 437 stations, indicating capital gain over the last ten years at 98.2% of stations measured.
Notably, 121 stations, or 27.2%, saw RV surpassing 150%.
Only 8 stations experienced a decline in RV, with capital losses of less than 10%.

The station with the highest RV among those surveyed was Shin-Ochanomizu station on the Tokyo Metro Chiyoda Line, reaching 295.5%, nearly tripling in price over a decade.
The average price per tsubo (about 3.3 square meters) at the time of construction was 4,248,000 yen, while the resale price per tsubo after 10 years was 12,552,000 yen.
However, it's important to note that the surveyed cases at this station primarily consisted of properties from large-scale tower condominiums, all located on floors 20 or higher, which may have skewed the results upward.
Following closely were Roppongi-Itchome station at 265.7% (new construction: 4,796,000 yen / tsubo, resale: 12,742,000 yen / tsubo), and Iidabashi station at 223.1% (new: 3,938,000 yen / tsubo, RV: 8,784,000 yen / tsubo).
The top 30 stations were all within the 23 wards of Tokyo, with the highest-ranking station outside of the 23 wards being Shin-Yokohama station, ranking 64th with 163.2% resale value.
