JapanHow to use will storage at Legal Affairs Bureau?
You can deposit a notarized will with the Legal Affairs Bureau for secure, official storage; it requires submission in person with identification and payment of a fee.
What the Law Says
Japan’s Civil Code and the Notarization Act govern wills, but no statute explicitly mandates or regulates will storage at the Legal Affairs Bureau. Instead, the practice is authorized under the Ministry of Justice’s administrative rules for notarial services.
Only notarized wills (kōshō shōsho) may be deposited — handwritten (shinseki) or secret (himitsu) wills are ineligible. The Bureau does not review validity but confirms formal compliance before acceptance.
Once deposited, the will is sealed and stored indefinitely; access is restricted until the testator’s death and verification of inheritance proceedings.
What to Do
Visit your local Legal Affairs Bureau with the original notarized will, valid ID (e.g., My Number card or passport), and ¥3,900 fee.
Complete the deposit application form onsite; staff will verify documents, seal the will, and issue a deposit certificate.
