Compare municipalities using one 30-tsubo model

The table below is a planning model using 30 tsubo of land and 30 tsubo of floor area, ordered from the highest modeled total. Published transaction counts use each municipality's latest year, generally 2025. It is separate from the prefecture-level borrower results above.
