Six years. That’s how long an empty house sat two doors down from one of my rental properties before the city finally stepped in. The roof had partially caved in, weeds were taller than the fence, and the owner living in Osaka simply stopped answering calls. When the local government designated it a tokutei akiya (specially designated vacant home), the owner’s property tax bill jumped by roughly 6 times overnight. That single number is the whole reason Japan’s vacant home rules matter to any landlord here, including me.
I’ve managed 9 rental properties across two decades, and at various points I’ve owned or inherited buildings that could easily have slid into vacant home status if I hadn’t acted. Understanding how the tax incentives and penalties work has saved me over 2 million yen in avoidable costs on a single property. Here’s what I’ve learned from actually dealing with the system, not just reading about it.
Why Japan Cracks Down on Vacant Homes

Japan currently has more than 8 million vacant residential units nationwide, and that number keeps climbing as the population shrinks and ages. Empty houses attract pests, become fire hazards, and drag down the value of every property around them, mine included. Back in 2015 the national government passed the Act on Special Measures for Vacant House Policy, which gave municipalities the legal authority to inspect, warn, and eventually penalize owners of neglected buildings. Before this law, there was actually a strange incentive to leave a house standing and empty: residential land normally gets up to a 1/6 reduction on fixed asset tax (kotei shisanzei) compared to vacant land. Owners would let a house rot for decades just to keep that tax break. The 2015 law closed that loophole for the worst offenders.

If a municipality inspects your vacant property and finds it dangerous, unsanitary, or badly neglected, they can label it a tokutei akiya. Once that happens, you lose the residential land tax discount entirely, and your fixed asset tax can rise by roughly 6 times for the land portion alone. In my area, that took one owner’s annual bill from about 45,000 yen to over 270,000 yen. You typically get a formal warning first, with a window of around 90 days to fix the problem before the designation and tax change actually take effect. I’ve seen owners ignore that warning letter because it looked like a routine notice, which is the single most expensive mistake I’ve watched a neighbor make.
The Incentive Side: Demolition and Renovation Support
The flip side of the penalty is real money on the table if you act early. Most municipalities now offer demolition subsidies for vacant homes, and in the towns where I own property, that support has ranged from about 300,000 to 1,000,000 yen depending on the building size and how long it’s been vacant. Some cities also offer renovation grants, typically covering 30 to 50 percent of renovation costs up to a set cap, if you convert the vacant house into a rental or bring it back into livable condition within a set timeframe. There’s also a capital gains tax special deduction available when you sell an inherited vacant home after demolishing it or after making it meet current earthquake resistance standards, which can shave up to 30 million yen off the taxable gain in qualifying cases. I used a version of this deduction on a property I inherited from a relative, and it turned what would have been a tax headache into a manageable one.

Due Diligence Checklists & Guides

Three years ago I picked up a small single-story house near one of my other rentals. It had been empty for about 4 years before I bought it, sitting right on the edge of tokutei akiya territory. Instead of waiting, I applied to the local government’s renovation subsidy program within the first 2 months of ownership. The application process took about 6 weeks, and I received 480,000 yen toward a roughly 1.5 million yen renovation that included a new roof section, updated wiring, and insulation work. That grant alone covered nearly a third of the job. I now rent that unit out for 62,000 yen a month, and because I moved before any designation, my fixed asset tax stayed at the standard reduced residential rate the entire time.
A Practical Checklist Before You Buy or Inherit a Vacant Property
Whether you’re picking up a cheap akiya as an investment or you’ve inherited one from family, run through these steps before the clock starts working against you:
- Check with the local city or town office whether the property has already received any vacant home warning notices.
- Confirm the current fixed asset tax classification and whether the residential land discount still applies.
- Ask about demolition and renovation subsidy programs specific to that municipality, since amounts and eligibility rules vary a lot by area.
- Get a structural inspection within the first month, especially for anything vacant longer than 2 to 3 years.
- Set a firm renovation or demolition timeline, ideally within 6 to 12 months, rather than letting the property sit while you decide.
Mistakes I’ve Watched Other Landlords Make
The biggest one is treating the first warning letter as optional. It isn’t. The second most common mistake is assuming every municipality offers the same subsidy amount; I’ve seen neighboring towns with subsidy gaps of over 400,000 yen for what is basically the same size demolition job, so it pays to call the actual city office rather than relying on general advice online. The third mistake is holding onto an inherited vacant house for sentimental reasons without running the tax math, because that 6 times tax jump doesn’t care about sentiment. If a property has been sitting empty for more than a couple of years, get moving on either fixing it up or tearing it down before the city makes that decision for you.
That’s the approach I use across all 9 of my properties: check the vacant home status first, apply for whatever subsidy is on the table, and never let a building sit empty long enough for the city to notice before I do.
