The skill will ask you for:
- Property address (物件住所)
- Transaction type: 売買 (sale) or 賃貸 (lease)
- Use type: 居住用 (residential) or 事業用 (commercial)
- Whether the property is a 区分所有建物 (condominium unit)
Then it generates a checklist, fetches publicly available data, and outputs an Excel report.

- Flood Hazard (from 国土地理院): 洪水浸水想定区域あり（浸水深0.5〜3.0m）
- Landslide: Outside designated hazard zone (hillside area nearby has yellow/red zones)
- Tsunami / Storm Surge: No risk (inland, elevation ≈40.7m)
