Published residential-land transactions are aggregated across 4 full neighborhoods whose representative points lie within 1.5 km straight-line distance of the station. The neighborhood breakdown appears below.
| Neighborhood | Median / m² | Latest year · samples |
|---|---|---|
| Yamaguchi | JPY 90,750 / m²JPY 90.75K / m² | 2025 · 12 |
| Arahata | JPY 77,138 / m²JPY 77.138K / m² | 2025 · 8 |
| Kotesashiminami | JPY 117,975 / m²JPY 117.975K / m² | 2025 · 3 |
| Kotesashidai | JPY 169,400 / m²JPY 169.4K / m² | 2024 · 1 |
Each neighborhood uses its most recent transaction year within the five-year dataset, which may differ from the station-area year shown above. The 1.5 km rule uses representative-point distance.
The green circle is a 1.5 km radius; orange points are neighborhood representative points.

Directions use each neighborhood representative point relative to the station. They do not classify individual transaction coordinates.
Valley lowland is a broad terrain classification. Use it as context for drainage and ground conditions, not as a property-level safety determination.
The elevation range within 250 m is about 8.5 m. Absolute elevation alone does not determine flood risk; compare the property with nearby roads and mapped inundation.
AVS30 (278 m/s) indicates average ground stiffness to 30 m depth. The amplification factor (1.36) compares shaking tendency; neither determines a building's seismic performance or need for ground improvement.
At the station representative point, mapped flood status is outside and landslide-warning status is outside. Verify the exact property on official maps because conditions vary within the 1.5 km area.
These values describe the Shimo-Yamaguchi Station representative point, not every property in the station area. Check official hazard maps, disclosure documents and plot-specific ground investigations before purchase.
