Greater Tokyo existing condo transactions rise for 10 straight months in August 2025

The Real Estate Information Network for East Japan (REINS) released data on September 10th showing continued momentum in the Greater Tokyo Area’s (GTA) existing real estate market in August 2025.

The GTA consists of the following prefectures; Tokyo, Kanagawa, Chiba and Saitama.

All percentages illustrate Year-on-Year (YoY) percentage changes; in other words, August 2024 compared to August 2025.

Transaction records in Japan are voluntarily reported rather than legally mandated.  While the transaction upward trend is clear, to what extent agents in 2025 are reporting more transactions versus actual buyer demand is unclear.

For agents, the more transactions that are recorded, the cheaper the cost is to use the broker-accessed only MLS.
