50-Tsubo Land in Japan: 2026 Prices, House Size & Costs
A 50-tsubo (165.29 m²) residential lot costs roughly ¥141.55 million (approx. USD 943,700) in central Tokyo's 23 wards versus about ¥19.40 million (approx. USD 129,300) in Sapporo — a spread most international buyers cannot check against an MLS-style closed-sale database, because none exists in Japan. This guide uses 2026 Japanese government data to show exact land prices by region, the buildable floor area under Japan's dual coverage-ratio and floor-area-ratio system, total build cost, mortgage tax deduction limits, and how many rental units or parking spaces a 50-tsubo lot supports.
