Listing checked 2026-10-21

An owner-change unit is offered for sale with a tenant in place, with the listing explicitly marked “owner change” or “currently rented.” The buyer cannot move in immediately. In this list, 1 units fall into this category and are excluded from the price range and median above. The sale valuation reflects the estimated level for an ordinary vacant unit. Current rent and gross yield are shown only when stated in the listing (“approx.” means current rent × 12 ÷ asking price).

The difference from the sale valuation shows how far the asking price is above (+) or below (−) the estimated sale value. Asking prices normally exceed estimated sale values because they precede reductions and negotiation. Overall INDEX is the composite TOWERS SELECT INVESTMENT INDEX score, a 50-point-based relative assessment of all currently listed units.(calculated 2026-10-21）. A breakdown is provided on each unit page. This does not guarantee the closing price or future value.

Because Management Fee was not entered, a monthly amount of JPY 21,559 is estimated from the median per-square-meter amount for 3 same-building records (active listing).
Because Repair Reserve was not entered, a monthly amount of JPY 15,052 is estimated from the median per-square-meter amount for 3 same-building records (active listing).
Because no direction was entered, the estimate uses the model's neutral value.
Because corner-unit status is unknown, the estimate uses standard-unit conditions.
The estimate assumes a vacant sale or rental. It does not reflect interior condition, views, or individual lease terms. If the unit is renovated, select that optional condition to include it in the sale estimate.
This is an indicative estimate based on the entered conditions. It does not identify a specific active listing and may differ from the estimate on a unit page.

How to Read the Figures, Calculation Method, and Sources

Indicative nearby land value: Prices for the listed points are weighted by the inverse of each point's stored distance from the building. For points with verified coordinates, map and list distances are straight-line measurements from the building's current coordinates. If those coordinates were updated, they may differ from the distances used in the calculation. This is not a site valuation adjusted for land use or road conditions.
Change from previous year: Year-on-year changes at the same locations are weighted by distance. “—” means no comparable value is available.
5-year annual average (CAGR): This converts the change since five years ago into an annual rate, assuming the same rate each year. It is not the total five-year increase. Only comparable points are weighted by distance.
