Found a Japanese Sword in an Estate: First Steps
Estate clearances sometimes turn up Japanese swords—in closets, storerooms, or ancestral family collections. When possession transfers through inheritance, the Firearms and Swords Control Law (Juto-ho) creates legal obligations. The first question is always: does a registration certificate (torokusho) exist?
A torokusho is the document issued by a prefectural Board of Education proving lawful possession of a specific sword. It's typically stored with the sword, but may be filed elsewhere in the home.
When a Registration Certificate Exists
If a valid torokusho exists and the recorded details (blade length, curvature, signature) match the actual sword, the heir should take the following steps.
1. Notification of ownership change (recommended, not strictly required)
The Juto-ho does not explicitly require updating the registered owner's name on the torokusho. However, to avoid complications in future sales or transfers, voluntarily notifying the prefectural Board of Education is strongly advisable. Submit both the deceased's and heir's information using the Board's prescribed form.
2. Inter-prefectural transfers
If relocating the sword to a different prefecture (e.g., when moving house), notification to the destination prefecture's Board of Education may be required. Confirm requirements with the relevant Board.
3. Inheritance tax valuation
Nihonto included in an estate must be declared at fair market value as of the date of death. Obtain a valuation certificate from a specialist sword dealer or an appraisal organization such as the NBTHK. For Important Cultural Properties, valuations from the Agency for Cultural Affairs or national museums may be referenced.
When No Registration Certificate Exists: Required Procedure
Possessing an unregistered sword is a violation of the Juto-ho. Legal obligations arise the moment an unregistered sword is discovered through inheritance. The correct procedure:
- Secure the sword in a location where it cannot be easily accessed
- Report to the nearest police station (Community Safety Division) promptly after discovery—ideally within 14 days
- Police will inspect the sword and guide you through the registration application process
- Apply to sit the certification examination (torokusho shinsakai) at the prefectural Board of Education
- Upon confirmation as a genuine sword, a torokusho is issued
The shinsakai uses specialist appraisers to confirm authenticity. Pre-modern genuine swords are typically approved. Replicas and poor-quality pieces may be denied registration.
Risk of non-reporting: Illegal possession of an unregistered sword can constitute a violation punishable by up to 3 years imprisonment or a ¥500,000 fine. Prompt police reporting is essential.
Selling or Disposing of Inherited Swords
For selling an inherited sword (with a valid torokusho), consult a licensed sword dealer (kobutsu-sho) as the safest route. Licensed dealers operate under the Antique Dealing Act, minimizing legal risk for both parties.
An unregistered sword cannot be sold until after the police reporting and registration examination process is complete.
Summary
Inheriting a Japanese sword involves the intersection of inheritance tax law, the Firearms and Swords Control Law, and cultural property protection. Confirm torokusho existence first; proceed with voluntary notification and tax valuation if registered, or immediate police reporting if unregistered. For complex cases, consult the prefectural Board of Education or a lawyer specializing in sword law.
