Is headline yield enough to judge a Tokyo property investment?

更新日: 2026-09-02 / 最終確認日: 2026-09-02

Answer

No. Headline yield is only a starting point. Actual investment performance also depends on management fees, repair reserves, property tax, leasing costs, vacancy and repairs.

Numbers to check

  • Expected annual rent
  • Annual fixed and variable costs
  • Vacancy and arrears assumptions
  • Purchase price and exit assumptions

Using official data

Use MLIT transaction and land-price data to test whether the acquisition price is reasonable, while calculating returns from the property’s own income and expense figures.

Sources and verification

This Q&A uses the same MLIT primary sources as the related Regional Guide and was verified as of September 2, 2026. Recheck current data and property documents for an individual investment.
