- Because Management Fee was not entered, a monthly amount of JPY 15,194 is estimated from the median per-square-meter amount for 6 same-building records (active listing).
- Because Repair Reserve was not entered, a monthly amount of JPY 14,638 is estimated from the median per-square-meter amount for 6 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.
