What to check before you rent or buy

• Not coloured means the Geospatial Information Authority tile has no flood colour here. Some prefecture-managed rivers are missing from that dataset.
• No national liquefaction tile. Check the municipal hazard map before you offer. This screen does not paint liquefaction.
• Straight-line distance, not the walk.
