Why should hazard review happen early?
Hazard exposure is a filtering condition, not just a final checkbox.
Even when a property is inexpensive, flood or landslide exposure can change insurance, renovation priorities, resale confidence, and whether the property works for day-to-day living.
Which hazard signals matter first?
For many rural homes, the practical first pass is flood, landslide, and steep-slope exposure. After that, region-specific checks such as earthquake, tsunami, or storm surge can be layered in.
- Flood: river proximity and low-lying land
- Landslide: hillside and valley-edge exposure
- Steep slope: immediate slope adjacency

FAQ
Should buyers automatically reject properties with hazard flags?
Not automatically, but they should not justify the risk with price alone. Hazard exposure changes the property decision in practical, financial, and lifestyle terms.
Can Akiyama hazard data replace official maps?
No. It helps with comparison and prioritization, but official municipal maps and source verification remain the final reference.
