Adopt national as-of-right building codes.
The key concept I'm describing is often called “as-of-right” development or “by-right” permitting. In Japan specifically, this works through:
- Yōto chiiki (用途地域) — the 12 (now 13) nationally standardized zoning categories that define what's allowed in each district.
- Kenchiku kakunin (建築確認) — a “building confirmation” process, which is a ministerial/technical check that the plans comply with the code, not a discretionary permit. If your building meets the code for its zone (use, height, floor-area ratio, setbacks, etc.), confirmation must be issued. There's no public hearing, no neighbor veto, no discretionary review.
So while permits technically are required, they're non-discretionary.
