Japan Rent Monitor, 2026Q2: Greater Tokyo Singles' Rent Tops ¥100K Then Slips Two Months; Family Units Hit Record ¥161K

This launches our quarterly Japan Rent Monitor, tracking listed rents in greater Tokyo and Kansai as a gauge of living costs and buy-to-let conditions. June 2026 delivered a split verdict. Greater Tokyo single-type rents averaged ¥100,574, up 19.2% year on year — but after first breaking the ¥100,000 barrier in April (a record since data began in January 2020) and peaking at ¥101,250, they have now fallen two months running. Family-type units, by contrast, hit a fresh record ¥161,230, up 16.4%. In Kansai, single-type rents reached a record ¥65,726 (+10.6%) while family-type came in at ¥90,459 (+10.3%), the second-highest on record — Kansai still runs at roughly 65% of Tokyo-area levels. The six-year arc is steep: comparing each June, single-type rents have climbed 38.2% since 2020 and family-type 66.6%, with most of the gain packed into the past two years. One caveat matters: these are asking rents on new listings. Renewal rents and the housing component of official price statistics move far more slowly, so this series measures what a new mover faces today, not the average tenant's bill — and the gap between old and new contracts keeps widening. For movers, the two-month slip in singles' asking rents suggests a friendlier second half; for investors, record family-type rents versus a topping singles' market makes unit selection matter more than timing.
