How long do I have to renounce an inheritance in Japan?

Three months. The courts state that the application must be made within three months from the time you learn that the inheritance has commenced — which is not necessarily the date of death, an important distinction if you were told late. This is general information rather than legal advice, so confirm your own deadline with the family court concerned or a qualified professional.

Which court handles inheritance renunciation in Japan?

A family court. Jurisdiction lies with the family court covering the deceased's last place of residence in Japan — not the court nearest the property, and not one near where you live. If you are overseas, this is one reason heirs usually work with a professional in Japan.

Can I renounce only the house and keep the rest of the estate?

No. Renunciation in Japan is all-or-nothing: you give up the entire estate, cash and property alike. If the estate has valuable assets alongside an unwanted house, renouncing means losing both, so the arithmetic is worth doing carefully before you file.

What happens if I miss the 3-month renunciation deadline in Japan?

In general, the opportunity to renounce is lost and you are treated as having accepted the inheritance, along with its obligations — including any debts and the ongoing duties of owning the property. Because the consequences are serious and circumstances vary, seek advice from a lawyer or judicial scrivener as early as possible rather than waiting until the window has closed.

Does renouncing an inheritance make the Japanese property disappear?

No. Renunciation removes you from the line of succession, but the property passes to the next heir in order. It does not dissolve the estate or transfer the house to the state automatically, which is why families usually discuss renunciation together rather than deciding individually.

Do I have to register a house I inherited in Japan?

Yes. Since April 1, 2024, inheritance registration (相続登記) is mandatory. You must register within 3 years of learning of the inheritance, on penalty of a fine of up to ¥100,000. Inheritances that occurred before April 2024 must be registered by March 31, 2027.

Can I refuse to inherit just the house and keep the rest?

No. Renunciation (相続放棄) is all-or-nothing — you give up the entire estate, including cash and other assets. It must be filed with the family court within 3 months of learning of the inheritance.

What is Japan's land-to-state program (相続土地国庫帰属制度)?

A system introduced in 2023 that lets heirs transfer inherited land to the national government. Conditions are strict: no buildings (houses must be demolished first), no contamination, and no disputes. It costs a ¥14,000 examination fee per parcel plus a burden payment starting around ¥200,000 if approved.

What tax do I pay if I sell an inherited house in Japan as a non-resident?

Capital gains are taxed at 15.315% for long-term holdings (the deceased's ownership period counts toward yours). If the original purchase records are lost, the acquisition cost is deemed to be 5% of the sale price, making roughly 95% of the proceeds taxable. A special deduction of up to ¥30 million may apply to qualifying older vacant houses sold within about 3 years of inheritance.

What happens if I leave an inherited Japanese house empty and do nothing?

Taxes continue to accrue with penalties, and the municipality can designate a deteriorating house as 管理不全空家 (poorly managed) — revoking the residential land tax break and raising fixed asset tax up to 6×. In serious cases the municipality can demolish the house and bill the owner. All warnings arrive by physical mail in Japanese.

Inherited a House in Japan from Overseas? Your 4 Options

Every year, thousands of people living outside Japan inherit a family home they never planned to own — often a rural house that has been empty for years. Since 2024, ignoring it is no longer a legal option: Japan has made inheritance registration mandatory, and municipalities now have real power to penalize neglected houses.

This guide walks through the mandatory first step, then compares your four realistic options.

Step Zero: The Deadlines You Cannot Skip

Inheritance registration (相続登記) is mandatory since April 1, 2024. You must register within 3 years of learning of the inheritance, on penalty of an administrative fine of up to ¥100,000. Inheritances that occurred before April 2024 must be registered by March 31, 2027.
Renunciation has a much shorter window. If you intend to refuse the inheritance entirely (see Option 4), the family court filing must be made within 3 months of learning of the inheritance.
Overseas heirs must register a Japan-based contact (国内連絡先) in the property registry when registering — a requirement in force since April 2024.
Japanese inheritance tax may also apply, with a filing deadline of 10 months from death.

With the paperwork underway, here are your options.

Option 1: Sell

The cleanest exit for heirs with no plans to use the property.

What to expect:

Capital gains tax: as a non-resident you pay 15.315% on long-term gains (the holding period includes the deceased's ownership). See our capital gains guide for non-resident sellers.
The 5% trap: if the original purchase contract is lost — common for houses bought decades ago — the acquisition cost is deemed to be 5% of the sale price, meaning roughly 95% of the proceeds are treated as taxable gain. Search hard for the old records before you sell.
A special deduction may help: the vacant-house inheritance deduction (相続空き家の3,000万円特別控除) can exempt up to ¥30 million of gain for qualifying older homes sold within about 3 years of inheritance — conditions are strict (pre-1981 construction, demolition or seismic retrofit, sale price ≤ ¥100 million), so confirm eligibility with a tax professional.
Rural liquidity is poor. In depopulating areas, finding a buyer can take years. Municipal akiya banks widen the audience at low price points.

Best for: heirs who want closure and whose property has a real market.

Option 2: Rent It Out

Turning the house into income sounds attractive — and sometimes is — but go in with clear numbers.

Renovation first: houses empty for years typically need ¥2–10 million of work before they are rentable. See our guide to managing Japanese contractors from overseas.
Withholding tax: rent paid to a non-resident owner is generally subject to 20.42% withholding, and an annual Japanese tax return is required.
You will need local management — tenant relations, repairs, and rent collection cannot be done from another country.
Run the yield honestly: in many rural markets, achievable rent does not justify the renovation cost. In tourist or regional-city locations, it can.

Best for: properties in locations with genuine rental demand, owned by heirs willing to invest upfront.

Option 3: Keep It — as a Second Home or for the Future

Many heirs keep the family home for visits, retirement plans, or simply because parting with it feels wrong. That is a legitimate choice — as long as you budget for it and stay compliant.

Annual carrying costs to budget:

Fixed asset tax and city planning tax
Fire and earthquake insurance
Basic utility contracts and periodic maintenance (Japan's humidity is merciless to closed-up houses)
A management arrangement — someone must check the house, and you must be reachable for official mail

Compliance duties for non-resident owners: appoint a tax representative (納税管理人), register your Japan-based contact, and keep your registered address current (mandatory from April 2026). Every official notice arrives as physical mail in Japanese.

Best for: heirs with an emotional or future stake in the property who can commit to the running costs.

Option 4: Give It Up

Two formal routes exist for heirs who want neither the property nor its obligations: renouncing the inheritance, or handing inherited land to the state.

Renunciation (相続放棄): the 3-month court deadline

Renunciation is an application made to a family court — not a form you send to a city office, and not something you can do by simply ignoring the estate.

The deadline is 3 months. According to the courts, the application must be made within three months from the time you learn that the inheritance has commenced — that is, from when you find out, which is not always the date of death. For an overseas heir told late about a relative's passing, that distinction matters.
Which court: the family court with jurisdiction over the deceased's last place of residence in Japan — not the court nearest the property, and not one near you.
It is all-or-nothing. You renounce the entire estate. You cannot keep the savings and refuse the house.
Renouncing passes the estate on. It does not make the property disappear; it moves to the next heir in line, which is worth discussing with your family before you file.
Possession carries duties. If you are already in possession of the property, a duty to preserve it can continue until the next heir or an administrator takes over.

The practical trap for overseas heirs is time. Three months disappears quickly when you are gathering documents from another country, arranging translations, and deciding as a family — so if renunciation is a serious possibility, get advice early rather than at the end of the window.

The land-to-state program (相続土地国庫帰属制度)

Since 2023, inherited land can be transferred to the national government if it meets strict conditions — no buildings (the house must be demolished first), no contamination, no disputes. Expect an examination fee of ¥14,000 per parcel and, if approved, a burden payment starting around ¥200,000.

Best for: estates where the property is a pure liability — but the 3-month renunciation window means you must decide fast.

Please note: this section is general information, not legal advice. Deadlines, required documents, and court procedures depend on your individual circumstances, and the consequences of renunciation are permanent. Confirm the details with the family court concerned, or consult a qualified professional such as a lawyer or judicial scrivener, before acting.

The One Option That Does Not Exist: Doing Nothing

Before 2023, many overseas heirs simply left the house alone. The rules have closed that path:

Unregistered inheritance now carries fines — and an unregistered house cannot be sold later without untangling the title.
A deteriorating house can be designated 管理不全空家 (poorly managed vacant house), stripping the residential land tax break and raising fixed asset tax up to 6× — the process is explained in our akiya guide.
In serious cases the municipality can demolish the house by administrative execution and bill the owner.
Meanwhile, every warning letter arrives at an address where nobody is reading it. That is how unmanaged properties spiral.
