Mt. Aso 9DK Group Villa — 528㎡, Dual Frontage, Caldera Views at ¥8M
9-room group villa near Aso Caldera. 528㎡, dual road frontage 7.6m+5m, 2 bathrooms. ¥8M. Aso: $193 ADR, $29K median revenue, +58.9% YoY.
At ¥8M (US$54K), this 9-room 192㎡ house in Aso City's Imamachi district represents the highest room-count-per-yen ratio in the portfolio. Nine separate rooms across a 2-story 528㎡ lot — with two bathrooms (one per floor) and dual road frontage (7.6m + 5m) for multi-vehicle group arrivals — makes this the most operationally scalable property for group STR pricing. At Aso's $193 ADR for the median listing, a 9-room group-rate property can realistically charge 3-4× the median per-stay — ¥30,000-50,000/night as a whole-house group booking is common in the caldera market. Mt. Aso (阿蘇山) is one of the world's largest calderas, spanning 25km × 18km, with an active volcano (Nakadake) visible from the property and hot spring access within 10 minutes. AirROI 2025–2026 records $193 ADR and $29,023 median annual revenue across 36 active Aso City listings, growing +58.9% YoY — the fastest growth rate in the Kyushu portfolio. Total investment ¥11.7–14.9M. Gross yield 37.0%, payback 2.7–3.4 years. Confirm sewage type and minpaku permit with Aso City before purchase.
Minpaku (short-term rental) status not confirmed. Verify with the municipal office and your agent before completing purchase. STR operation may be restricted to 180 days/yr or prohibited.
