-9.7% vs. latest actual
Japan’s housing-starts market is recovering from a low base. YHS-FE places FY2026 at 747,928 homes, +5.2% year over year. The next-month forecast is +6.5% year over year, while the six-month point is 59,991 homes, -9.7% versus the latest actual. This looks more like stabilization and rebound than a broad economic boom.
This classifies the housing-starts market, not the broader economy. Fixed four-signal count: 3 positive, 1 negative, 0 neutral.

Current Reading
Japan recorded 66,439 housing starts in July 2026, including 39,547 wooden units. YHS-FE places the national total near 64,000 one month ahead, 69,000 at three months, and 60,000 at six months.
The Japanese model draws more information from the recent mix of owner-occupied, rental, and for-sale starts than from one leading indicator. The twelve-month result remains close to a simple persistence forecast.
Japan also has a separate wooden-housing branch and a 47-prefecture panel. Medium-term prefectural values remain research candidates with only one complete temporal holdout.

Short-horizon figures are monthly wooden starts; medium-term figures are annual averages. Select a prefecture name to update the chart above.
The prefectural panel beat the seasonal benchmark at every tested horizon. At twelve months, RMSE improved by 5.3%, but sMAPE was 21.0% over only 20 target months. Accuracy is lower than at one month, and medium-term values have only one independent temporal holdout.

These wooden-housing scenarios anchor to the 2024–2028 annual average and apply the 2024 IPSS prefectural household projection. They are conditional sensitivities, not validated long-term point forecasts. The higher-rate case is a fixed 5% downside stress. The faster-decline case doubles household losses versus 2025. Neither is an estimated causal effect.

year over year
year over year
The U.S. housing market remains soft under high financing costs. The latest starts reading was -12.4% month over month and -13.5% year over year, while permits were +3.1% year over year. YHS-FE places the next month at 1,275 thousand SAAR, but -1.3% year over year does not yet signal a clear upswing.
This classifies the housing-starts market, not the broader economy. Fixed four-signal count: 1 positive, 3 negative, 0 neutral.
Official actuals: U.S. Census Bureau, New Residential Construction
Current Reading
From the July 2026 release, YHS-FE places U.S. housing starts near 1.274 million SAAR one month ahead, 1.272 million at three months, and 1.283 million at six months.
Permits were the clearest short-run signal in the historical test. The wider supply-pipeline model improved the one-month RMSE again, but the advantage did not survive at three, six, or twelve months.
The strict first-release-vintage backtest ends in August 2013. I update the current model each month, but I do not describe the post-2013 period as an equivalent real-time accuracy record.

Terms and Reading Guide
- RMSE
- Forecast error measure that penalizes large misses more heavily. Lower is better.
- sMAPE
- A symmetric percentage error scaled by the forecast and actual values.
- SAAR
- Seasonally Adjusted Annual Rate, the monthly pace expressed at an annual rate.
- Reference MoM
- A YHS display transformation using month factors estimated from Japan’s trailing 120 observations. It is not an official seasonal adjustment.
- Forecast revision
- The change from a previously stored forecast for the same target month. Different target months are not compared.
- Empirical frequency
- The share of historical backtest residuals meeting the current condition. It is not a guaranteed or calibrated probability.
- Breadth indicator
- Japan uses the share of prefectures above one year earlier; the U.S. uses the share of four starts-and-permits signals above one year earlier.
- 80% forecast range
- An empirical range based on the 10th and 90th percentiles of historical backtest residuals.
