Used House Appraisals in Tokyo Surge 33.8% in Under Two Years, Averaging Over 62 Million Yen—Data Analysis Reveals "Price Polarization"

Survey Report: Price Trends in the Used House Market

Speee, Inc. (HQ: Minato-ku, Tokyo; Representative Director: Hideki Otsuka; TSE Standard: 4499), the provider of the real estate appraisal system "Tsunagaru Online Assessment," has conducted a survey on national house price trends from May 2024 to February 2026, utilizing over 200,000 appraisal data points (including 20,000 in Tokyo). This survey clearly demonstrates a "polarization" in the real estate market, where rapid price surges in Tokyo are driving the national average, while downward trends are observed in regional areas.

*Note: To ensure comparative validity, all appraisal figures in this survey are calculated based on a floor area of 70 square meters.*

### 18.6% Increase Recorded in National Average

During the survey period (May 2024–February 2026), the average appraised value of used houses nationwide rose by approximately 18.6%, from 19.44 million yen to 23.05 million yen. While there are monthly fluctuations, the rise in new home prices—driven by increased material and labor costs—has spread to the used housing market, resulting in a Compound Monthly Growth Rate (CMGR) of +0.78%.

### Polarization Between Tokyo and Regional Areas

The national average is heavily driven by the surge in Tokyo. The average appraisal in Tokyo climbed from 46.62 million yen to 62.36 million yen (a 33.8% increase, CMGR +1.33%). In contrast, regions excluding Tokyo saw an increase of only 2.76%. Specifically, Hokkaido, Tohoku, and Shin-etsu regions experienced declines, with Hokkaido seeing a 16.7% drop from 12.42 million yen to 10.35 million yen. This widening real estate gap between urban and regional areas underscores the increasing importance of location selection.

### Structural Background of Price Increases

The survey identifies three structural factors behind the rise in national real estate prices: 1. **Surging Material Costs:** Inflation has driven up new home prices, boosting demand for used properties as an alternative. 2. **Rising Interest in Used Housing:** Due to a focus on cost-performance and the growth of the renovation market, preference for used homes has increased. 3. **Low Interest Rates and Tax Benefits:** Historically low interest rates and tax incentives for used real estate have fueled market demand.
