Average required funds are the official total corresponding to average land acquisition and construction costs for the same survey group. Median lot area and average floor area are separate descriptive statistics and do not describe one representative property.

Compare a consistent 100 m² model

The 100 m² model is not the Japanese average; it is a compact hypothetical model used to compare every prefecture under the same conditions. In the FY2025 Flat 35 survey, the national median lot area was 206.1 m² and the average floor area was 110.3 m². This model is separate from the borrower results above and does not determine whether a 100 m² building can be built on an individual lot.
