Japanese Sword Laws: Complete Guide to the Firearms-and-Swords Law, Torokusho Registration, Ownership, Trade, and Carrying Penalties

Introduction: Is the Japanese Sword an "Art Object" or a "Weapon"?

Japanese swords are craft works valued worldwide, and many are designated as "Important Cultural Properties" or "Important Art Objects" by the state. However, they are simultaneously dangerous objects as blades capable of harming people. For this reason, Japan has established clear rules governing all aspects of possession, carrying, transportation, and export under the "Firearms and Swords Control Law" (銃刀法). Since unknowingly violating these rules can result in criminal penalties, enthusiasts, collectors, and those who have inherited swords are strongly encouraged to read this article in full.

Scope of the Firearms and Swords Control Law: Which Swords Are Regulated?

Article 2 of the Firearms and Swords Control Law regulates swords with a blade length of 15 cm or more. In the case of Japanese swords, nearly all exceed this standard.

The swords specifically subject to regulation are as follows:

• katana: A standard long sword with a blade length of approximately 60 cm
• wakizashi: Blade length of approximately 30–60 cm
• tanto: Subject to registration even with blade length under 30 cm
• naginata and yari (spear): Subject to similar regulation though with different blade length standards

On the other hand, practice swords (non-authentic swords) or iaido training swords (such as zinc-alloy models) do not fall under the Firearms and Swords Control Law's definition of "swords," but may be subject to separate "blade regulations" if they have a blade length of 15 cm or more.

Registration System: Notification to the Board of Education is Essential

The only legal way to possess a Japanese sword is to obtain a "Registration Certificate." Unregistered Japanese swords are illegal to possess, even if they have value as art objects.

Registration Process

1. Application for Examination: Present or mail the sword to your prefectural Board of Education to undergo registration examination. Examinations are held several times per year (frequency varies by prefecture).
2. Examination Criteria: The examination determines whether the sword is "a Japanese sword with value as an art object or antique." Manufacturing method, shape, and historical context are verified.
3. Issuance of Registration Certificate: Upon passing the examination, a "Registration Certificate" is issued in the name of the prefectural Board of Education. The certificate records the sword's characteristics (length, signature, shape, etc.).
4. Cost: The examination fee varies by prefecture but is generally several thousand yen.

In Case of Inheritance or Transfer

If you inherit or receive a registered sword, you must file a change-of-ownership notification with your prefectural Board of Education within 20 days (Article 17 of the Firearms and Swords Control Law). Failure to file this notification is subject to penalties.

If You Discover an Unregistered Sword

If an unregistered sword is found during estate settlement or warehouse cleanup, it must be promptly reported to the nearest police station. If reported, you will not face charges for possession; however, if left unreported, you may be prosecuted for illegal possession.

Rules for Possession, Carrying, and Transportation

Possession is legal with a registration certificate, but there are clear distinctions between "possession," "carrying," and "transportation."

Home Possession

It is legal to keep a sword at home with its registration certificate. However, theft or loss must be promptly reported to the police.

Transportation (Movement)

Taking a sword outside your home requires proper justification. Examples of recognized justifications include:

• Bringing the sword to a sword shop, appraisal meeting, or museum
• Transporting it to a craftsperson for polishing or repair
• Moving it for sale or transfer
• Bringing it to an iaido or battojutsu dojo (for martial arts purposes)

When transporting, always carry the registration certificate, and keep the sword sheathed in a sword bag or protective case. Carrying an exposed sword is considered "carrying" and is illegal without proper justification.

Prohibition on Carrying in Public

Article 22 of the Firearms and Swords Control Law prohibits carrying blades without proper justification. Walking with a drawn Japanese sword on a public road is illegal regardless of blade length, and arrests have been reported.

Procedures for Taking Swords Abroad

Exporting Japanese swords abroad requires procedures under multiple laws.

Regulations Under the Cultural Properties Protection Law

Swords designated as Important Cultural Properties or Important Art Objects are generally prohibited from being taken out of the country. Even for undesignated swords, export requires an "Antique Art Export Inspection Certificate" from the Agency for Cultural Affairs, Cultural Properties Division 1 (or the Export Examination Section of the Kyoto National Museum). The registration certificate becomes invalid upon export and must be returned to the Board of Education.

Foreign Exchange and Foreign Trade Act

In some cases, such as high-value art and craft works, export declaration to the Ministry of Economy, Trade and Industry under the Foreign Exchange and Foreign Trade Act may be required (this is typically not necessary for most antique Japanese swords).

General Export Procedure

1. Obtain an Antique Art Export Inspection Certificate from the Agency for Cultural Affairs (submit the registration certificate; it must be returned to the Board of Education after export)
2. File an export declaration with customs (at the airport or port) and present the original inspection certificate and a copy of the registration certificate
3. Check the import regulations of the destination country in advance (some countries prohibit or strictly restrict the import of swords)

Important note: Swords cannot be carried in the cabin (they must be checked as baggage with proper packaging), and airline rules for checked blades vary. It is essential to confirm with your airline in advance.

Penalties for Violations

Violations of the Firearms and Swords Control Law are serious crimes that can result in imprisonment, despite appearing minor. Here are the main violations and their penalties:

Actual cases include individuals who kept unregistered swords found in a grandfather's estate without reporting them to police, and those who unknowingly possessed authentic Japanese swords thinking they were replicas. The claim of "not knowing" is not a legal defense, so early reporting is critical.

Summary: Proper Knowledge Protects Swords

Japanese swords can be legally possessed, appreciated, and sold by anyone who follows proper procedures. The two critical points are the presence of a registration certificate and proper justification for carrying or transporting. Regardless of whether you inherit, purchase, or discover a sword, consulting with the Board of Education or police is the best first step. Following the law helps preserve and pass on Japanese swords as cultural heritage to future generations.

What Happens If You Possess a Japanese Sword Without a Firearms and Swords Registration Certificate?

Merely possessing an unregistered sword constitutes a violation of the Firearms and Swords Control Law and is subject to imprisonment for up to 3 years or a fine of up to ¥500,000 (Article 31-16 of the Firearms and Swords Control Law). If an unregistered sword is discovered during inheritance or estate settlement, the legal course is to file a discovery report with the nearest police station before moving it, then obtain a registration certificate through the prefectural Board of Education's registration examination.

Do You Need a License to Store a Japanese Sword at Home?

Unlike firearms, no license is required to possess a registered Japanese sword. However, the registration certificate must be kept with the sword, and you must file a change-of-ownership notification with the prefectural Board of Education each time the sword is transferred, inherited, or sold. Failure to file this notification puts you in a state of non-ownership and exposes you to the same risk of Firearms and Swords Control Law violations.

What Is Illegal About Taking a Japanese Sword Outdoors?

"Carrying without proper justification" is not merely a minor offense under Article 22 of the Firearms and Swords Control Law; hidden carrying is subject to imprisonment for up to 2 years or a fine of up to ¥300,000. Attending appraisals, registration examinations, repairs, or bringing a newly purchased sword home are recognized justifications, but you must be prepared for police questioning with evidence such as protective packaging (with no exposed blade), the shortest route taken, and notes on the destination and time of transport.

What Legal Precautions Should Be Taken When Buying or Selling a Japanese Sword?

The sale itself is legal, but the original registration certificate must be transferred along with the sword, and the buyer must file a change-of-ownership notification with the Board of Education within 20 days. A used-goods dealer license under the Antique Goods Sales Act is required for conducting business through continuous trading, but private transactions between individuals are exempt. Do not overlook that sales to overseas customers require a separate Antique Art Export Inspection Certificate from the Agency for Cultural Affairs, and the registration certificate becomes invalid at export and must be returned to the Board of Education.
