## The Worsening Vacant House Problem and the Expansion of Demolition Subsidies
According to the Ministry of Internal Affairs and Communications' Housing and Land Survey (2023), the number of vacant houses nationwide reached approximately 9 million, with a record-high vacancy rate of 13.8% (Source: Ministry of Internal Affairs and Communications Housing and Land Survey 2023). Under the revised Act on Special Measures concerning Vacant Houses enacted in December 2023, a new category of 'Poorly Managed Vacant Houses' was established in addition to the traditional 'Specific Vacant Houses'. If designated as a poorly managed vacant house, the special provision for residential land regarding fixed asset tax (reduced to a maximum of one-sixth) may be revoked. Against this backdrop, an increasing number of owners are considering the option of demolishing buildings to create vacant land. A major burden in doing so is the demolition cost. For wooden houses, the standard is generally 30,000 to 50,000 yen per tsubo (approx. 3.3 sqm), meaning a 30-tsubo house would cost around 900,000 to 1.5 million yen. Meanwhile, many municipalities have established subsidy systems for demolition costs as part of their vacant house countermeasures, but the names, eligibility requirements, maximum limits, and application deadlines for these subsidies vary greatly by municipality. While based on the Ministry of Land, Infrastructure, Transport and Tourism's comprehensive support project for vacant house countermeasures, some municipalities have set up their own additional systems, making it difficult to collect comprehensive information.
## How the Target Checker Works
The Target Checker displays a list of applicable subsidy systems by simply inputting three pieces of information.
**Input Items**
- Building location (prefecture, city/ward/town/village)
- Building structure (wooden/steel frame/RC)
- Building age (approximate is acceptable)
**Output Results**
The following information regarding the applicable municipal subsidy system is displayed:
- System name
- Maximum subsidy amount (e.g., up to 500,000 yen, within 1/2 of the cost)
- Main eligibility requirements (conditions for vacant house certification, owner requirements, building age requirements, etc.)
- Application acceptance period and submission destination
- Points to note (a note stating that many systems end as soon as the budget limit is reached)
Since the details of subsidy systems may change each fiscal year, the data is updated regularly. The information displayed is strictly an overview, so please confirm the official requirements at the respective municipal office.
## Use Case 1: Considering Disposal of an Inherited Vacant House
When deciding whether to 'demolish or sell' a vacant house inherited from parents, knowing the difference between the demolition cost and the subsidy amount beforehand can serve as a factor in the decision. For example, if the estimated demolition cost is 1.2 million yen and a municipal subsidy of 500,000 yen is available, the actual burden is 700,000 yen. By comparing this with the expected sale price of the land after clearing it, one can judge whether it is economically rational. By combining this with the diagnosis function of 'Demolition Cost AI', you can perform everything from cost estimation to subsidy confirmation in a one-stop manner. The deadline for filing inheritance tax is 10 months from the occurrence of inheritance, and the application period for the 30 million yen special deduction for capital gains on a vacant house is for transfers within 3 years from the occurrence of inheritance (Source: National Tax Agency Special Measures to Suppress the Occurrence of Vacant Houses). Because these are time-sensitive decisions, it is crucial to grasp the overall cost picture at an early stage.
## Use Case 2: Considering Rebuilding an Aging Home
If you live in a wooden house that is over 40 years old, it may not meet seismic standards. For buildings that received building confirmation before May 1981 (old seismic standards), some municipalities offer demolition cost subsidies separate from seismic retrofitting. By checking for subsidies using the Target Checker and incorporating the subsidy into the total rebuilding budget, the accuracy of your financial planning will increase.
## Use Case 3: Purchasing Decisions by Real Estate Businesses
When real estate businesses purchase land with an old house, the demolition cost directly impacts the purchasing cost. By researching the subsidy system in the property's location beforehand, it can be utilized as material for purchasing decisions. When comparing multiple candidate properties, the presence or absence of a subsidy often sways the decision.
## Regarding the Accuracy of Subsidy Data
The subsidy information published in this tool is based on official information announced by each municipality. However, subsidy systems may close applications mid-year depending on budget execution status. Also, the revision or abolition of systems...
