Site | OpenAPI |
Japan rules index (machine-readable)
One file with the thresholds, fees, effective dates and official sources behind every Japan rule tool: /rules.json (human-readable: /rules.md). It is copied from each tool's own /api/rules, which stays the live source of truth; rebuild with python3 scripts/build-rules-index.py. Educational summaries, not legal, tax or immigration advice.
