Editorial interest 78/100 Selection signal · not a rating of the site

Calculators estimate national housing subsidies for heating equipment, windows, renovations and new homes, alongside a directory of municipal programs.

Landing page captured for the 2026-10-10 issue.

For: Japanese homeowners planning energy-saving work
Worth noticing: The directory lists 81 municipal programs across 42 municipalities, with 65 marked as accepting applications.

Field notes

The homepage separates national-program calculators from municipal listings and budget-status tracking. It gives concrete boundaries for several estimates, including a ¥1 million per-home ceiling for window work and a ¥50,000 minimum combined application; the site cautions that final amounts depend on the work, application timing and remaining budget.
