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 13,988 is estimated from the median per-square-meter amount for 4 same-building records (active listing).
  • Because Repair Reserve was not entered, a monthly amount of JPY 10,589 is estimated from the median per-square-meter amount for 4 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.

Dates are this site's observation dates. “New” means first seen, while a removed listing does not necessarily indicate a completed transaction and may include withdrawals. Listing duration is an estimate based on the information date, update date, and first observation date, and may differ from the actual listing start date. Days with unconfirmed collection or unit aggregation are treated as missing and are not connected by lines.

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.
