Location & Neighborhood

Investment Perspective
Building depreciation: In Japan, buildings depreciate significantly over time. Wood-frame houses depreciate to near-zero value at around 22 years, while RC structures depreciate more slowly but still lose value. At 34 years old, much of the building's value has already depreciated — the price largely reflects land value and location premium.
Scale advantage: With 52 units, this is a relatively large condominium. Larger buildings typically benefit from lower per-unit maintenance and repair reserve costs.
Key cultural note: Unlike the US where properties typically appreciate over time, Japanese buildings depreciate while the underlying land tends to hold or gain value. This means buyers should evaluate the land-to-building value ratio carefully.
