Investment Perspective
Seismic standards: Built in 1973, this property predates Japan's 1981 New Seismic Design Standards (新耐震基準). Buildings constructed before June 1981 were built to older earthquake resistance codes. Buyers should consider seismic retrofit status.
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 53 years old, much of the building's value has already depreciated — the price largely reflects land value and location premium.
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.
