Dealing with inheritance procedures as a foreigner in Japan can feel overwhelming, especially when you are grieving and still navigating a language barrier. Whether you have inherited property, bank accounts, or other assets in Japan — or someone overseas has left you assets that cross borders — this guide walks you through the key legal requirements and practical steps. Think of this as a starting point: always confirm the latest rules with a qualified professional or official source, as procedures and tax thresholds can change.
Who Can Inherit in Japan? Basic Rules for Foreign Residents
Japan's inheritance law does not exclude foreigners. Under Japanese law, heirs are generally determined by the nationality of the deceased, not the heir. This means:
- If the deceased was a Japanese national, Japanese inheritance law (Civil Code) applies to assets located in Japan, regardless of whether the heirs are foreign nationals.
- If the deceased was a foreign national, the law of their home country may govern who inherits — but Japanese law typically applies to real estate physically located in Japan.
- Foreign residents in Japan can both inherit and be subject to Japanese inheritance tax on assets they receive.
Because cross-border estates can involve two countries' legal systems at once, it is strongly recommended to consult a licensed judicial scrivener (shiho shoshi) or a lawyer (bengoshi) with experience in international estate matters.
Key Steps for Inheritance Procedures in Japan
Step 1 — Obtain the Death Certificate
As soon as possible after the death, a death notification (shibo todoke) must be filed at the local municipal office within seven days (14 days if the death occurred overseas). This generates the official death record. You will need certified copies of this record for almost every subsequent step.
Step 2 — Gather the Family Register Documents
The Japanese family register (koseki) is central to proving family relationships and identifying all legal heirs. You will need to collect the complete family register history of the deceased — going back far enough to confirm all potential heirs. Request these from the municipal office where the deceased was registered.
If you are a foreign national heir, you will typically need to provide:
- Your passport (certified copy)
- A certificate of residence (zairyu card or juuminhyo)
- Documents proving your relationship to the deceased (birth certificate, marriage certificate, etc.), often with a certified Japanese translation
Step 3 — Check for a Will
Japan recognises several types of wills. If the deceased left a notarised will (kosei shosho yuigon), it is stored at the Legal Affairs Bureau and can be searched nationally. A handwritten will (jison shosho yuigon) must go through a family court process called ken'in (will verification) before it can be acted upon. If there is no will, heirs must agree on how to divide the estate through a written agreement called a 遺産分割協議書 (estate division agreement).
Step 4 — Reach an Estate Division Agreement
If there is no will, all legal heirs must sign a formal estate division agreement. This document needs to be agreed upon unanimously — even one heir living overseas must participate. For foreign residents or overseas heirs, a notarised signature and apostille (or equivalent authentication) from their home country may be required. A judicial scrivener can help draft this document correctly.
Step 5 — Transfer Assets into Your Name
Once the agreement or will is confirmed, you can transfer assets:
- Real estate: Register the change of ownership at the Legal Affairs Bureau (homukyoku). From April 2024, registration of inherited real estate is legally mandatory in Japan within three years of learning of the inheritance.
- Bank accounts: Each bank has its own procedure. You will generally need the death certificate, family register documents, the estate division agreement, and your own identification. Contact the bank directly and ask for their inheritance procedure documents (sozoku tetsuzuki shorui).
- Securities and other assets: Contact the relevant financial institution with similar documentation.
Step 6 — File an Inheritance Tax Return if Required
Japan's inheritance tax can apply to foreign residents depending on their visa status and how long they have lived in Japan. The rules are complex and have changed in recent years — the general threshold and rates vary based on the total value of the estate and the number of heirs. As a guide, if the total inherited assets exceed the basic deduction (calculated as a base amount plus a per-heir amount), a tax return must be filed within 10 months of the date of death. Confirm the current thresholds with the National Tax Agency (nta.go.jp) or a certified tax accountant (zeirishi).
Common Documents You Will Need
| Document | Where to Get It |
|---|---|
| Death certificate / death notification copy | Municipal office where death was registered |
| Complete family register of deceased | Municipal office (may require multiple offices) |
| Your residence certificate (juuminhyo) | Your local municipal office |
| Your passport (certified copy) | Your own records; certification at a notary if needed |
| Relationship documents (birth/marriage certificate) | Your home country, with Japanese translation |
| Estate division agreement | Drafted with a judicial scrivener or lawyer |
| Seal or signature authentication | Notary public (in Japan or your home country) |
Practical Tips for Foreign Residents
- Act within the deadlines. The 10-month tax filing deadline and the new 3-year real estate registration requirement are strict. Mark these dates early.
- Get translations done officially. Any foreign-language document submitted in Japan usually needs a certified Japanese translation. Keep originals safe.
- Consult a bilingual professional. Many judicial scriveners and tax accountants in major cities offer English-language consultations. The Japan Legal Support Center (Houterasu) can refer you to affordable legal help.
- Transferring inherited money overseas? If you need to send inherited funds from a Japanese bank account to your home country, services like Wise or Remitly can be cost-effective options. Check current transfer limits and fees on each platform's official site, as rates change frequently.
- Be patient with banks. Japanese banks can take several weeks to process inheritance claims, even with complete paperwork. Follow up politely and keep records of every submission.
Summary: What to Remember About Inheritance Procedures for Foreigners in Japan
Inheritance procedures as a foreigner in Japan involve several moving parts — confirming legal heirs through the family register, reaching a signed estate division agreement, transferring assets, and meeting tax deadlines. The good news is that foreigners are fully entitled to inherit in Japan, and the process, while document-heavy, is manageable when you take it one step at a time.
Start by gathering the death certificate and family register documents, consult a bilingual judicial scrivener or lawyer early, and keep a close eye on the 10-month tax deadline. For anything involving real estate, note that mandatory registration is now the law. With the right professional support and a clear checklist, you can work through this process even with limited Japanese. You are not alone — many foreign residents have navigated this successfully, and help is available.
