Before you buy a Japanese sword from Japan, the single most important thing to confirm is how your own country treats it on arrival. The Japanese export side is routine for ordinary art swords, but the import and ownership rules differ enormously from one jurisdiction to the next. This hub gives a verified one-line summary for six countries and links to a dedicated page for each, so you can read the detail and check the primary sources yourself.
Sword Ownership Laws by Country
The table below summarises how each country treats a genuine traditionally made nihonto, both for owning it and for bringing it in. Each claim links the relevant government source. The rules are general and can change, so treat this as a starting point and always verify against the current law before you buy. Where the law is set at the state or provincial level, the summary is necessarily hedged.
In the six countries covered here, owning a genuine traditionally made nihonto is broadly lawful, but the conditions differ. The UK restricts curved swords while exempting traditionally made and antique blades, and in Australia ownership is set state by state, so a katana can be prohibited in some states without an exemption. Always check the specific country page and your local law before buying.
Do I need a licence to own a Japanese sword?
Usually no. The US, Canada, Germany, and France do not require a licence to own a sword as an adult, and the UK allows traditionally made and antique nihonto under an exemption. Australia is the main exception, where some states require an exemption or permit. A licence-type requirement is far more common for importing or carrying than for simply owning at home.
Can I carry a sword in public?
Almost universally, no, not freely. Germany and France allow ownership but restrict carrying a sword in public without a legitimate reason such as a sporting, cultural, or professional purpose, and Canada similarly expects a lawful reason. Treat a sword as something to keep and display at home rather than carry, and check local rules for any transport.
Is a replica treated the same as a genuine antique sword?
Often not, and sometimes the replica faces the stricter rule. The UK exemption, for example, protects traditionally made and antique swords but not cheap mass-produced reproductions. Authentication papers such as NBTHK certificates and the Japanese registration history are the evidence used to show a blade is a genuine nihonto rather than a replica.

A few patterns are worth noting before you dig into any single country. In the United States there is no federal statute banning ownership of a sword; the federally regulated bladed category is switchblades, and U.S. Customs and Border Protection does not list traditional swords as prohibited imports, though individual states regulate carry and sale. In Canada the federal position is similar, with the Criminal Code prohibited-weapons list aimed at automatic, gravity, and concealed-blade knives rather than swords, so a katana is admissible on a routine customs declaration. Germany and France both separate ownership from public carry: an adult may freely own the sword, but carrying it in public is restricted and generally needs a legitimate reason. The United Kingdom bans cheap curved swords yet carves out a specific exemption for traditionally made blades, which is the most important rule for nihonto collectors and is covered next. Australia is the outlier: the main barrier is state possession law, not the import step, since the federally controlled bladed categories are double-edged daggers and concealed or disguised blades such as cane swords, while a traditional single-edged katana with a visible scabbard is generally admissible on a customs declaration.
What Makes Authentic Nihonto Different Legally
The clearest illustration of why authenticity matters legally is the United Kingdom. The Criminal Justice Act 1988 (Offensive Weapons) (Amendment) Order 2008 added "a sword with a curved blade of 50 centimetres or over in length" to the list of weapons it is an offence to sell, import, or manufacture. That measure was aimed at the flood of cheap, mass-produced "samurai swords" used in violent crime. Crucially, the schedule as amended by SI 2008/2039 provides a defence where the weapon "was made before 1954 or was made at any other time according to traditional methods of making swords by hand," as set out in the Criminal Justice Act 1988 (Offensive Weapons) Order 1988 schedule. Note the wording is country-neutral — the defence turns on age or traditional hand-forging, not origin — so a genuine traditionally made nihonto falls squarely within it on either branch, while a cheap reproduction does not. Antiques over 100 years old are also separately exempt from the underlying offence under the same 1988 Order.
This is the legal heart of the matter across most jurisdictions: the law often treats a genuine, traditionally made or antique sword very differently from a modern replica or wall-hanger, and sometimes the replica faces the *stricter* rule. Being able to prove authenticity is therefore not just about value, it can be the difference between a lawful import and a prohibited one.
This is where authentication papers earn their place. Most quality nihonto carry papers from the NBTHK confirming the blade is genuine traditionally made nihonto, and many also have a documented history through the Japanese registration card (登録証) system. Together these are the evidence a collector relies on to demonstrate that a sword is the real thing rather than a reproduction. Our NBTHK certificate guide explains what these papers say and why they matter.
A practical caution follows from all of this. Replicas, modern decorative reproductions, and unsharpened practice pieces are not genuine nihonto and frequently sit under entirely different, occasionally stricter, rules than a papered antique. Do not assume that because a real sword is allowed, a lookalike is, or the reverse.
Before You Buy
Start on the Japan side by understanding how the sword actually leaves the country: deregistration of the registration card, the Agency for Cultural Affairs export certificate, and insured shipping. Our how to buy from Japan guide walks through that process in full. The export of an ordinary art sword is handled by the seller as a matter of routine.
Then confirm the import and ownership rules for where you live by reading the dedicated page for your country and checking it against your own customs and police authorities, because rules change and the summaries here are general. If you are unsure which sword suits your situation, you can ask through our consultation window or submit a search request. This page is general information, not legal advice, so verify the current rules before you commit.
