Three years ago I looked up a property two towns over from one of my own rentals and found it listed in the municipal vacant house registry with a note that it had been empty for 14 years. That single database entry told me more about the risk and the opportunity in that building than the listing photos ever could, and it changed how I evaluate every empty property I come across now.
If you own rental property in Japan, or you are thinking about buying one, understanding how the long-term vacant building registry works is not optional. It affects your tax bill, your relationship with the city office, and in some cases whether you are allowed to keep the building standing the way it is. I have dealt with this system directly on 3 separate properties, and the rules are far more mechanical than most owners realize.
What the Registry Actually Records

Every municipality in Japan is required under the Act on Special Measures for Vacant House Countermeasures (u7a7au5bb6u7b49u5bfeu7b56u7279u5225u63aau7f6eu6cd5) to maintain some form of vacant property database. In practice this is rarely a single searchable website. Most cities keep an internal ledger, called something like akiya daicho (u7a7au304du5bb6u53f0u5e33), that combines utility usage records, resident registration data, and reports from neighbors. Roughly 30 percent of the municipalities I have dealt with across three prefectures also publish a simplified public version, usually just an akiya bank listing addresses that owners have voluntarily submitted. Records in the internal ledger are typically kept for at least 5 years after a property is delisted, which matters a great deal if you plan to resell.
The internal ledger is the one that matters for enforcement. It logs the date the building was first confirmed vacant, the number of inspection visits, and whether the structure has been classified as tokutei akiya (u7279u5b9au7a7au5bb6u7b49), meaning specified vacant house, a designation that unlocks stronger city intervention. I always assume these notices exist even when a seller claims otherwise, because I have been wrong about that assumption before.

Most entries start with a neighbor complaint or a routine utility check. If the water meter shows zero usage for 12 consecutive months, or an inspector notices overgrown vegetation and a collapsed gutter during a drive-by survey, the address goes into the tracking system. In my experience it usually takes only 2 or 3 neighbor complaints within a single fiscal year before an inspector is actually dispatched to look at the building.
I have seen this go wrong twice with properties I later purchased. In both cases the previous owner had moved without updating their address, so three separate notices piled up unanswered before I closed on the deal. The lesson I took from that: always ask the seller directly whether the property has ever received a vacant house notice, and get it confirmed in writing before you sign anything.
The Tax Trigger Every Landlord Should Know
This is the part that actually costs money. Residential land normally qualifies for a fixed asset tax reduction of up to five sixths off the assessed value. Once a building is formally designated tokutei akiya and the owner ignores the city’s improvement request, that reduction can be removed entirely. I watched a colleague’s annual fixed asset tax on a 90 square meter lot jump from roughly 28,000 yen to nearly 170,000 yen the year after his designation notice went unanswered, close to a sixfold increase that hit on the very next tax cycle. Cities are generally required to issue at least one written advisory and wait about 6 months before pulling the reduction, so there is a real window to respond if you catch the notice in time.

Due Diligence Checklists & Guides
Never skip due diligence. These tools help you ask the right questions.
Before making an offer on any property that looks like it has been sitting empty, I take three steps every time:
- Call the city’s akiya taisaku (vacant house countermeasures) desk directly and ask whether the address has an open case file, rather than relying on the seller’s word.
- Request a copy of the fixed asset tax certificate (u56fau5b9au8cc7u7523u7a0eu8a55u4fa1u8a3cu660eu66f8) to check whether the residential land reduction is still being applied.
- Walk the property at two different times of day to look for utility meter movement, mail accumulation, and any posted city notices taped near the entrance.
This process takes me about two hours per property, and it has saved me from at least one purchase where the back taxes and required demolition estimate would have wiped out any profit for the first 4 years of ownership.
Getting a Property Removed From the List
Once a building is in the system, getting it delisted requires documented action, not just a phone call. Across the properties I have brought back from vacant status, the pattern has been consistent: submit a renovation or demolition plan to the city within 90 days of the first formal notice, complete visible exterior work such as roof repair or fence replacement, and then request a re-inspection. One of my properties went from tokutei akiya status to fully delisted in about 7 months, mostly because I kept a paper trail of every receipt and dated photo along the way, which made the re-inspection almost a formality.
What This Means for Your Bottom Line
The registry is not just a bureaucratic curiosity. It is the mechanism that decides whether a vacant property costs you a modest annual tax bill or turns into a demolition order with a bill attached. I check the vacant house ledger on every acquisition now, the same way I check the registry for liens, and it has become as routine as pulling the title report. That’s the approach I use across all 9 of my properties, and it is the first call I make before I ever put in an offer.
