From the listing

Two deteriorated properties: a former guesthouse and adjacent house. Photography dated May 2, 2026. Guesthouse built 1970, adjacent house built 1982. Guesthouse closed in 1994. No sales conditions attached. Located in the center of a tourist area; from the 2nd floor, you can see the sea pavilion and enjoy the sound of waves and starry sky. The newly renovated Ashizuri Marine Museum (nickname "SATOUMI") reopened in July 2020, suggesting demand for accommodation, restaurants, and cafes. Vacant since 2018. Significant deterioration and many repairs needed. The adjacent house was built with quality materials (owner's father worked for the forestry service). The field has a non-agricultural land certificate, so non-farmers can purchase. Issues: two roof leaks (near guesthouse entrance and kitchen of upper house); floor sagging in two locations (left-side room of guesthouse entrance and around center of upper house 2F); back hill is a landslide warning zone. Reinforcement from 2006 has cracking; wood portions have rotted and collapsed due to aging. Foundation cracks in approximately two locations; no changes observed to date.

The price in context

The nearest official land-price benchmark is about 13,800 yen per sqm, down about 8% over five years (15,000 to 13,800), which the survey classes as declining.

The asking price works out at about 2,751 yen per sqm of land, 80% below the nearest residential benchmark of about 13,800 yen per sqm. The benchmark is for bare land; akiya prices usually bundle a worn building, so a large gap is normal and does not by itself mean a bargain.

Official records

Area and hazard data

2 checks clear, 4 to know about. Each check is against a government map for this exact point. Where a map is missing or we can't use it, we say so; that never means there's no risk.

Hazards and ground
Earthquake code
Caution
Built before the 1981 earthquake code. Expect a structural survey, harder mortgages, and a retrofit budget; towns often grant part of that cost.

Source: Estimated from year built

Strong-earthquake chance
Warning
About 78% chance of a strong quake (shindo 6-lower or above) in 30 years, high for Japan, where most places sit between 3% and 26%

Source: National earthquake-hazard model

Landslide risk
Checked, clear
Checked: no designated landslide zone at this location. Zone edges are approximate, and this is not a legal property disclosure document.

Source: Government hazard map

Flood risk
Checked, clear
Checked: outside a mapped flood area. The maps cover designated rivers only, so this is not a promise of no flooding.

Source: Government hazard map

Tsunami risk
Warning
In a tsunami inundation zone, expected depth at least 10.0 m

Source: Government hazard map

Liquefaction
Note
Moderate liquefaction susceptibility. Ask for a ground report before major work.

Source: National landform survey

A pre-1981 build predates Japan's current earthquake code, which can matter for insurance and renovation. We flag the era from the year built where we have it.
