Minato rents are nearly twice the 23-ward average
East Japan REINS data for April through June 2026 recorded 18,218 apartment rental transactions across Tokyo's 23 wards, with an average monthly rent of ¥132,000, average floor area of 33.96 square meters and contracted rent of ¥3,899 per square meter. Minato Ward recorded 695 transactions at an average ¥246,000 per month, 41.00 square meters and ¥5,994 per square meter. The figures demonstrate how sharply rental economics differ even within Tokyo. Ward, station, building age, floor area and building grade can all materially affect attainable rent, making citywide averages insufficient for underwriting a specific investment property.
Contracted rent is more useful than advertised rent
Property portals make asking rents highly visible, but investors should base income assumptions on the level at which leases actually close. A landlord can advertise an aggressive rent, yet one or two additional months of vacancy may reduce annual income enough to offset the higher monthly figure. This effect is particularly important for premium central-Tokyo units because each vacant month represents a large absolute amount of lost rent. Overseas owners should obtain comparable contracted rents, typical marketing periods, renewal conditions and incentives such as free-rent periods from their property manager rather than relying exclusively on public listing prices.
Higher rents do not guarantee higher investment yields
Tokyo rents are high, but acquisition prices for investment apartments are also elevated. If property values rise faster than rents, gross yields can compress even while monthly rent increases. Net income is further reduced by management charges, reserve-fund contributions, leasing management fees, property tax, equipment replacement, restoration costs and vacancy. A high-rent location such as Minato should therefore not be treated as automatically producing a superior yield. For investors in 2026, the more useful framework is to compare actual contracted rent with acquisition price and sustainable occupancy, then deduct the full cost of ownership before evaluating the return.
