Buying Old Properties in Japan: The Hidden Opportunity in Aging Housing Stock
Japan has a housing stock problem that most people see as a liabilityu2014and that smart investors can turn into an asset. An estimated 8 million vacant homes (u7a7au304du5bb6) dot the Japanese countryside and suburbs. More than 6 million residential properties are over 40 years old. Conventional wisdom says avoid these properties. I disagree, and my portfolio is built on them.
Why Old Properties Are Priced So Low (and Why That’s Opportunity)

The books that changed how I think about money, leverage, and long-term wealth.
Japanese buyers overwhelmingly prefer new construction. Cultural bias, financing constraints (many banks won’t lend on pre-1981 properties without seismic upgrades), and the tax depreciation schedule that punishes old buildings all conspire to make used properties cheap relative to their income potential.
Consider: a new 2DK apartment in a mid-size city might rent for 55,000 yen per month and sell as a condo unit for 15 million yenu2014a yield of 4.4%. The 40-year-old wood-frame building down the street might have units renting for 40,000 yen, but the whole building sells for 8 million yenu2014a yield of 24% if fully occupied. Even at 75% occupancy, the old building generates a better return per yen invested.
The key insight: tenants don’t care nearly as much about building age as buyers do. If the unit is clean, functional, and reasonably located, tenantsu2014especially budget-conscious single workers and young couplesu2014will happily rent in an older building at a discount to market rates.

Cheap properties can be cheap for good reasons. My due diligence checklist for pre-1990 properties:
- Seismic standard (u8010u9707u57fau6e96): Built before June 1981? Get a seismic assessment (u8010u9707u8a3au65ad). Buildings that fail the assessment are difficult to finance and insure, and potentially dangerous. The assessment costs 100,000-200,000 yen but is essential.
- Foundation: Is there evidence of settling? Cracks running diagonally at corners? Have a structural engineer look at anything suspicious.
- Termites (u30b7u30edu30a2u30ea): In older wood-frame buildings, termite inspection is mandatory in my process. Termite damage can be severe and expensive. Inspection costs 20,000-50,000 yen.
- Asbestos (u30a2u30b9u30d9u30b9u30c8): Materials containing asbestos were common in Japanese construction through the 1980s. If you’re planning renovation work, have suspected materials tested before cutting or disturbing them.
- Plumbing: Galvanized iron pipe (u4e9cu925bu30e1u30c3u30adu92fcu7ba1) was commonly used through the 1970s-80s and corrodes over time, affecting water quality and pressure. Replacement cost for a small building: 500,000-1,500,000 yen.
- Electrical: Does the panel (u5206u96fbu76e4) have circuit breakers or old fuses? Is the wiring up to modern standards? Outdated electrical systems are both a safety risk and a barrier to getting good tenants.
The Renovation Business Model
My approach to old properties is not to buy them as-is and rent them cheaply. It’s to buy them cheaply, renovate them to a modern standard using my own DIY skills, and rent them at rates close to newer buildings.
A concrete example: I bought a 1983-built wood-frame 4-unit building for 6.5 million yen. The units were dirty, had old kitchen fixtures, and outdated bathrooms. Over 18 months, I renovated all four units during vacancy periods (I kept existing tenants undisturbed). Total renovation investment: 1.8 million yen, mostly done by me with some sub-contracted electrical and plumbing work.
Before renovation: units rented at 38,000-40,000 yen. After renovation: units rented at 48,000-52,000 yen. Annual revenue increase: approximately 480,000 yen. Return on renovation investment: 26.7%. That’s on top of the property’s underlying yield.

Spreadsheet analysis is the difference between a good deal and a disaster.
Akiyau2014abandoned homesu2014are the extreme end of old property investing. Prices can be astonishing: some rural akiya sell for under 1 million yen, and many municipalities offer akiya “banks” (u7a7au304du5bb6u30d0u30f3u30af) where properties are listed for free or nominal cost to encourage use.
I’ve looked at many akiya and bought none. Here’s my concern: the properties are cheap because the economics don’t work. A 500,000-yen akiya in a depopulating rural village requires 5 million yen in renovation and may only rent for 30,000 yen per month in a market with almost no rental demand. The math rarely closes.
Where akiya investing does work: properties close to cities with university or industrial employment bases, where the rental market is real and renovation costs can be recovered through rent. These deals existu2014you just have to search harder to find them.
