Guide to Disposal and Waste Management of Unwanted Nihonto—From Police Notification to Municipal Collection: Legal Obligations and Practical Procedures for Owners

When you own a Japanese sword, there eventually comes a moment when you think "I want to let go of it" or "I need to dispose of it." Whether you've inherited family heirlooms but can't manage them, want to organize your collection, or find storage difficult in your later years—the reasons vary, but disposing of swords as general household garbage is absolutely prohibited by law. The Firearms, Swords, and Bladed Implements Control Law (hereafter the "Sword Law") stipulates proper disposal procedures, and failure to follow them could make the disposal itself an illegal act. This article explains the concrete steps and precautions for safely and legally disposing of unwanted swords.

Confirming the Presence or Absence of a "Registration Certificate" Before Disposal

The first thing to confirm is whether the sword you wish to dispose of comes with a "Firearms, Swords, and Bladed Implements Registration Certificate" (registration certificate). The registration certificate is an official document issued by the board of education of each prefecture and is a necessary certificate to legally possess a sword.

The procedures differ greatly depending on whether a registration certificate is present or absent.

• Swords with a registration certificate: These are legally possessed items, and you can choose any disposal method—sale, transfer, donation, or destruction.
• Swords without a registration certificate: There is a risk of "illegal possession," so you must promptly report to the police.

Additionally, if you inherit a sword as a family heirloom and cannot immediately locate the registration certificate, you can follow proper procedures by promptly filing a "discovery report" with the nearest police station, receiving a "discovery report receipt," and then applying for new registration with the prefectural board of education within 20 days. While the Sword Law does not stipulate a "two-week" reporting deadline, it is important to act promptly after discovery.

Police Report Procedures

If you possess a sword without a registration certificate, or if you wish to notify the police of a sword's existence regardless of whether you have a registration certificate, file a report with the Community Safety Division (or Regional Division) of your nearest police station. Prepare an identification document (driver's license, My Number Card, etc.), the registration certificate (if you have one), and documents that can explain the circumstances of finding the sword (copies of wills, inheritance documents, etc.), and visit the station's counter.

The officer will examine the sword and record the presence or absence of a registration certificate and the sword's classification. If there is no registration certificate, the sword may be temporarily kept at the police station, undergo examination by the prefectural board of education, and then a registration certificate may be issued (or it may be judged that issuance is not possible). This report is not only to avoid criminal responsibility, but is also the first step in enabling proper subsequent disposal.

Concrete Disposal Methods

There are four main methods for disposing of unwanted swords.

• Handing over to a police station: The simplest method is to bring the sword along with its registration certificate to your nearest police station and request disposal. Simply tell them you want to dispose of it as an unwanted item, and the police will handle it appropriately. While the sword's value will be lost, this is the most straightforward procedure. When bringing it in, wrap the sword securely in cloth and place it in a sword bag or cardboard box in a state where it "cannot be quickly removed."
• Sale or purchase request from sword dealers: If you are considering sale rather than disposal, request an appraisal from a professional sword dealer. If properly maintained, older swords may command high prices. Dealers affiliated with the National Federation of Sword Dealers and Traders are highly trustworthy. When selling, you must complete the registration certificate name change procedure (filing with the relevant prefectural board of education).
• Donation to museums, art galleries, shrines, or temples: For swords with historical or cultural significance, donating to local museums or related shrines and temples is also an option. While acceptance may be difficult in some cases, it is an effective means when you wish to preserve culturally valuable swords for future generations.
• Auction listing: Auctions regularly held by organizations such as the Japanese Art Sword Preservation Association (NBTHK) offer the expectation of fair pricing. Keep in mind that listing fees and appraisal fees will be incurred.

Local Government Sword Retrieval Systems and Cost Estimates

Some municipalities have their own "hazardous materials collection" systems. However, these are primarily aimed at reporting and collecting illegally possessed or unregistered swords, and differ from disposal systems for legally registered swords with registration certificates—note this important distinction.

Be cautious about online businesses advertising "free collection of unwanted swords." We strongly recommend requesting appraisals from multiple dealers and comparing them.

Summary—The Principle of Legal Disposal

The disposal of unwanted swords is based on the premise of "compliance with legal procedures." The registration certificate system defined by the Sword Law is an important system for making sword locations traceable and preventing illegal distribution. Whether disposing or selling, following proper procedures is the responsibility of the owner.

If you are unsure, we recommend first consulting with your nearest police station or the relevant department of your prefectural board of education. From how swords are handled to how they are let go, culture and courtesy accompany every aspect—please proceed with disposal while valuing this spirit.
