A Guide to Japanese Real Estate Inheritance: When to Consult a Judicial Scrivener, Tax Accountant, or Attorney

Inheriting real estate in Japan is a distinctively different challenge from inheriting cash or securities. A house or a piece of land cannot simply be split three ways the way a bank balance can — someone has to get a professional appraisal, someone has to update the legal ownership record, and someone has to file the right tax paperwork, often all at once. As Japan's population ages and inheritance cases multiply, an increasing number of perfectly ordinary families — not just wealthy ones — are ending up in what is sometimes called sōzoku arasoi (争族), a wordplay on sōzoku (相続, “inheritance”) and arasoi (争い, “conflict”) that Japanese media use to describe inheritance disputes among relatives.

This Is a Uniquely Japanese Problem: Why Do Property Inheritance Disputes Happen So Often in Japan?

Unlike cash, which divides cleanly among heirs, real estate in Japan almost never does — and that indivisibility, combined with family emotion, is exactly what fuels sōzoku arasoi. The more heirs there are, the higher the risk: a sibling who was never told about a half-brother or half-sister from an earlier marriage may suddenly surface as a co-heir, or a sibling who provided years of unpaid elder care may insist, understandably but without clear legal footing, on a larger share of the estate. The common assumption that “our family isn’t wealthy enough for this to become a problem” is, in practice, backwards — modest, single-property estates cause proportionally more disputes in Japan than large, diversified ones, precisely because there is only one asset to fight over and no cash cushion to equalize shares. For an overseas reader used to jurisdictions where an executor or a single estate attorney can walk an estate from probate to distribution, it is worth noting up front that Japan handles this very differently, splitting the process across three separate licensed professions with non-overlapping authority — which is the subject of the rest of this guide.

Why Should You Consult a Professional at All for a Japanese Real Estate Inheritance?

A Japanese inheritance case sits at the intersection of three separate legal disciplines — civil law, tax law, and the real property registration system — and no single professional license in Japan covers all three. Handling it yourself on the basis of what you think you know is a genuine risk, because Japan's inheritance-related statutes are revised with some regularity, and a family member's prior experience settling an estate five or ten years ago may no longer reflect current law. The mandatory inheritance-registration rule discussed later in this guide is itself a recent example: it did not exist at all before April 2024. For a foreign heir living outside Japan, or an overseas investor who has acquired Japanese property through inheritance, this matters even more, because remote administration adds language, notarization, and cross-border tax questions on top of the domestic complexity.

Where Should You Turn for Advice on a Japanese Real Estate Inheritance?

In contrast to the US or UK model, where a single probate attorney (or a licensed estate agent) typically manages the entire inheritance file from start to finish, Japan legally separates this work among three distinct, non-substitutable professions. Knowing which one to call — and when — is the single most useful piece of practical knowledge in this guide.

Judicial Scrivener (shihō shoshi, 司法書士): Best for Title Transfers and Registration Procedures

A shihō shoshi (司法書士, literally “judicial document writer,” roughly analogous to a licensed conveyancer in common-law systems but with a narrower, registration-focused mandate) holds the legal authority to file real estate registration applications on a client's behalf. Their work covers the transfer of ownership registration, court-based verification (kenin, 検認) of a will where required, and the paperwork that changes the name on title. Resolving a dispute between heirs falls outside their legal authority, so a shihō shoshi is the right first call when the family is not in conflict and the task is purely administrative — get the property correctly and promptly re-registered in the heirs' names.

Tax Accountant (zeirishi, 税理士): Best for Inheritance Tax Filing and Property Valuation

Valuing the inherited real estate, drafting the estate division agreement (isan bunkatsu kyōgisho, 遺産分割協議書) for tax purposes, and — critically, whenever an inheritance tax filing is required — filing that return, are all zeirishi (税理士, “tax accountant,” Japan’s licensed profession for tax filings, distinct from a general accountant) territory. Because the appraised value assigned to a property can vary meaningfully depending on which zeirishi handles the case, and that valuation directly changes the tax bill, choosing a zeirishi with a strong specific track record in inheritance tax — not simply a generalist who also does inheritance work occasionally — is one of the highest-leverage decisions in the entire process.

Attorney (bengoshi, 弁護士): Best for Resolving Disputes Among Heirs

When an heir refuses to negotiate, stops responding, or otherwise will not cooperate, a bengoshi (弁護士, Japan's licensed attorney, the only one of the three professions authorized to represent a client in court) becomes essential for mediation (chōtei, 調停) or, if necessary, a family court ruling. A bengoshi can also draft the estate division agreement, but their fees typically run higher than a shihō shoshi's or zeirishi's — reflecting the fact that they are the only professional of the three licensed to litigate if a settlement cannot be reached.

What Should You Expect to Pay for a Consultation?

• Judicial scrivener or tax accountant: for a consultation only, roughly ¥5,000 per hour (approx. $32 USD at 155 JPY/USD) is a typical benchmark.
• Attorney: roughly ¥10,000 per hour (approx. $65 USD at 155 JPY/USD) is a typical benchmark — reflecting the broader scope of authority described above.
• Free municipal consultation counters: useful for getting oriented on general direction, but time-limited and not well suited to a detailed case review.

Beyond the hourly consultation fee, registering an inheritance triggers Japan's registration and license tax (tōroku menkyo zei, 登録免許税), and a tax filing brings its own separate costs. These are not one-time expenses either: once the property passes to the heirs, it continues to generate an annual fixed asset tax (koteishisan zei, 固定資産税) — Japan's recurring municipal property tax, roughly comparable to a US property tax bill but assessed and billed differently — and if the heirs later sell the property, income tax (shotokuzei, 所得税) on any capital gain applies as well. An overseas investor evaluating whether to keep or sell an inherited Japanese property should budget for this full lifecycle of cost, not just the initial registration fee.

FAQ: Common Questions About Consultation Options for Japanese Real Estate Inheritance

Q. Do I need to consult a professional even if the family isn't in conflict?

A. Yes. Consulting a shihō shoshi or zeirishi is recommended even without any dispute, simply because of how procedurally complex the process is and how often the underlying law changes.

Q. How do I know whether inheritance tax applies at all?

A. A filing is required once the total estate value exceeds the basic exemption (kiso kōjo, 基礎控除): ¥30 million (approx. $193,500 USD at 155 JPY/USD) plus ¥6 million (approx. $38,700 USD) multiplied by the number of statutory heirs. Confirming the property's appraised value with a zeirishi is essential, since real estate valuation for tax purposes is rarely as simple as market price.

Q. What if one of the heirs refuses to cooperate?

A. Mediation or a family court ruling through a bengoshi is the most reliable path to resolution when direct negotiation has broken down.

Q. By when does the property title need to be transferred?

A. Since April 2024, inheritance registration has been made legally mandatory in Japan — a genuinely new requirement, since before this date there was no legal deadline at all for updating the title. Heirs must file within three years of becoming aware that they inherited the property, and unlike the discretionary, unenforced norm that existed for decades beforehand, missing this deadline can now carry a financial penalty.
