空き家ナビ

This is a free resource to help you decide what to do with your inherited family home.

This is a private service based on public data, not an official service from the national or local government.

The reason people get stuck deciding what to do with their family home isn't because they lack information, but because researching price, taxes, and demolition costs separately doesn't give them a complete picture. Vacant House Navi allows you to simply select a city or town and tap on a house on the map, and all the necessary information will be displayed on a single page. No text input is required.

■ All You Need to Know in One Sheet
• How Much Is This House Worth? — A price "range" with justification, based on official transaction price information and land price announcements.
• What Risks Are There? — Flood, landslide, and tsunami scenarios are overlaid on a map.
• Is Rebuilding Possible? — A preliminary assessment based on zoning, building coverage ratio, floor area ratio, and road access.
• What Needs to Be Done and By When? — The 3-year deadline for inheritance registration and the 30 million yen special deduction deadline are shown in days.
• Available Systems — Systems from your local government and the national government.
• Estimated Profit and Loss for 5 Options — Sell / Rent / Live In / Demolish / Keep It As Is

■ We Won't Lead You to a Conclusion
We present the five options using the same scale, showing the "initial costs," "annual burden," and "amount remaining" as a range. We don't offer recommendations. The decision is yours.

■ No Sales Calls
This is not a bulk appraisal service. There is no mechanism for sending information from our service to businesses. You can create your consultation message using the app, but you will send it from your own email software.

■ Things We Do Not Ask For
• Bank account number, credit card number
• My Number (Social Security Number)
• Identification documents such as a driver's license
• Phone number

There are no fields to enter this information. We will not send SMS messages from this service. This is to avoid using the same methods as scams targeting owners of vacant properties.

■ Deadline Notifications
We will notify you of the application deadline for inheritance registration, the deadline for the 30 million yen special deduction, and the application period for local government subsidies 90 days, 30 days, and 7 days in advance. Since subsidies may close before the deadline if the budget is reached, this prevents you from realizing "it's over before I knew it."

■ No Membership Registration Required
You don't need an account or email address to view the reports. If you want to share with family, simply send them the URL, and they can view the same content and add comments without registering.

Vacant House Navi is a private service unrelated to the national or local government.

We do not provide real estate appraisal, valuation, brokerage, application document preparation, or tax return filing services. All displayed amounts are reference ranges based on public data; for final confirmation, please consult with local governments, legal affairs bureaus, tax offices, and qualified professionals such as judicial scriveners, tax accountants, and real estate agents.

We do not charge users. We operate through advertising. Advertisements do not affect the content or order of the report. We do not use browsing history, so we will not request permission for tracking.
