* Image is for illustrative purposes only.When a foreign collector visiting Japan thinks "I want to buy a real nihontō here in Japan," there is one important fact they need to know first.
Purchasing a nihontō is legal even for foreigners — however, the proper procedures must be followed. Conversely, ignoring the procedures carries the risk of having the sword confiscated upon returning home.
This article explains in detail everything from the legal requirements for inbound foreign visitors purchasing a nihontō at a domestic sword dealer in Japan to a practical shopping guide and the procedures for bringing the sword home.
In Japan, under the Act for Controlling the Possession of Firearms or Swords and Other Such Weapons (Jūtōhō), possessing a nihontō requires a "registration certificate (torokusho)."
What is a registration certificate: A document issued by the Board of Education of each prefecture (Article 14 of the Jūtōhō; Act for Controlling the Possession of Firearms or Swords and Other Such Weapons (e-Gov Law Search)) that certifies that a specific sword "has been properly registered as a work of art." Swords with a registration certificate may be legally possessed and bought or sold.
Foreign collectors and registration certificates:
Note: Swords that have not been registered (unregistered swords) may not in principle be purchased or possessed (Article 3, Paragraph 1 of the Jūtōhō). Trustworthy sword dealers always sell swords with a registration certificate.
When an inbound foreign visitor purchases a nihontō, the most important thing is "choosing a reliable shop."
How to identify a reliable shop:
Major sword dealer districts by area:
The following shows approximate price ranges for inbound foreign visitors actually considering a purchase.
| Category / Quality | Price Range (approximate) | Features |
|---|---|---|
| Entry class (Hozon Tōken, gendaitō) | 50,000–300,000 yen | With NBTHK Hozon kanteisho; mass-produced to unsigned swords in good condition |
| Mid-range class (Tokubetsu Hozon, renowned Edo-period smiths) | 300,000–1,500,000 yen | Authentic works by well-known tōkō or notable Edo-period signed pieces |
| High-end class (Jūyō Tōken and above) | 1,500,000–over 10,000,000 yen | Pieces designated Jūyō Tōken or Tokubetsu Jūyō Tōken |
| Kokuhō, jūyō bunkazai | Tens of millions to hundreds of millions of yen | Do not in principle come onto the market |
For a foreigner making their first purchase, the 50,000–300,000 yen "Hozon Tōken" class is a realistic option that keeps risks low while still acquiring a genuine sword with a kanteisho.
The following describes how the process actually unfolds from visiting a sword shop to completing a purchase.
Step 1: Entering the shop and viewing
Step 2: Checking the registration certificate
Step 3: Price negotiation
Step 4: Purchase and documentation
Several procedures are required to bring a purchased nihontō back to one's home country.
Procedure 1: Applying to the Agency for Cultural Affairs for an antique arts export inspection certificate When taking a nihontō registered as a work of art (an antique art object) overseas, an application to the Agency for Cultural Affairs is required under the Act on Protection of Cultural Properties. At the time of application, a copy of the registration certificate and other documents are submitted to obtain an "antique arts export inspection certificate." For standard export of art swords, the procedures of the Ministry of Economy, Trade and Industry (METI) and the Foreign Exchange and Foreign Trade Act do not apply.
Where to apply: Agency for Cultural Affairs (apply by mail; the address and forms can be confirmed on the Agency for Cultural Affairs website) Required documents: application form, photographs of the sword (both sides of the entire blade and the nakago), a copy of the front of the registration certificate, a return envelope for the certificate From application to issuance of the certificate: apply with ample time to spare
Procedure 2: Confirming that the sword is not a kokuhō, jūyō bunkazai, or jūyō bijutsuhin Swords designated as kokuhō (National Treasure) or jūyō bunkazai (Important Cultural Property), and swords recognized as jūyō bijutsuhin (Important Art Object), may not in principle be exported (Act on Protection of Cultural Properties, etc.). Whether a sword falls into these categories is verified by the Agency for Cultural Affairs through the antique arts export inspection certificate in Procedure 1 (Agency for Cultural Affairs, "Antique Arts Export Inspection Certificate"). An NBTHK kanteisho is a private appraisal and does not indicate a national designation or recognition.
Procedure 3: Customs declaration At customs upon departure, present the antique arts export inspection certificate (the original is submitted to customs), the registration certificate, and the sword to make an export declaration. Once the sword is taken out of Japan, the registration certificate becomes invalid at that point, and must be returned to the Board of Education of the prefecture where it was registered (Tokyo Metropolitan Board of Education, "When Exporting Firearms, Swords, and Similar Items").
Procedure 4: Procedures in the destination country When bringing the sword back home, the weapons import regulations of the destination country must be followed. Depending on the country, advance permission may be required (check requirements for the EU, the United States, Australia, and other countries).
An important note: nihontō may absolutely not be brought onto an aircraft as carry-on baggage.
Recommended transportation methods:
Reliable sword shops often have a network of shipping carriers and can be asked for transportation support at the time of purchase.
The following useful English expressions will help with communication at a sword shop.
Here is a summary of the key points for inbound foreign visitors to purchase a nihontō safely, legally, and with satisfaction.
By following the correct procedures, foreigners too can legally purchase a genuine nihontō in Japan and bring it home. Preparation in advance and choosing a reliable shop are the surest paths to the best possible sword-buying experience.
