How to Import a Katana into the UK: Law, VAT and Customs Explained

🗡 Browse authenticated Japanese swords at Tokyo Nihonto →

Is it legal to import an antique Japanese sword into the UK, given that British law bans curved swords over 50 cm? Yes, and the confusion is entirely understandable, because the headline of the 2008 legislation reads like a samurai sword ban while the small print does the opposite. This guide covers what the law actually says, what customs charges you will pay, and what the Japanese side has to produce before the parcel leaves Tokyo.

Are Katanas Legal in the UK?

Genuine antique Japanese swords are legal to import, own and sell in the UK. Section 141 of the Criminal Justice Act 1988 restricts curved swords with a blade of 50 cm or more, but antique weapons made more than 100 years before the date of the alleged offence are excluded from section 141 altogether, and every kotō, shintō and shinshintō blade meets that test with centuries to spare.

The chain of legislation matters, because people quote the 2008 order without the exemptions attached to it:

• Criminal Justice Act 1988, section 141. Makes it an offence to import, sell, hire, lend or give a weapon specified by order. The specified list is set out in the Criminal Justice Act 1988 (Offensive Weapons) Order 1988.
• The 2008 amendment order. Added swords with a curved blade of 50 cm or over to that list, which is where the "samurai sword ban" headlines came from.
• Offensive Weapons Act 2019. Extended the offence to possession in private of listed weapons, with the same defences preserved.
• The antique exclusion. The 1988 Order does not apply to antique weapons, defined as those made more than 100 years before the alleged offence.

So the position for a collector is straightforward. A Muromachi katana forged in 1520 is an antique, is outside section 141, and can be imported and owned in the UK without any special permission. A mass-produced curved sword bought last year is squarely inside section 141 unless it satisfies one of the statutory defences.

Which Exemptions Apply to a Genuine Nihonto?

Two apply directly. The first is the antique exclusion for anything over 100 years old. The second is the defence introduced in 2008 for swords made before 1954, or made at any time by traditional hand methods. A traditionally forged modern gendaitō made in Seki last year satisfies the second even though it fails the first.

The 2008 defence is worth reading carefully, because it was drafted with Japanese swords in mind and then widened. It covers a curved blade of 50 cm or more that was made before 1954, however it was made, or made at any other time using "traditional methods of making swords by hand", which the legislation describes in terms of hand labour or manually controlled methods that let the maker control and vary the construction, shape, design and finish.

That definition describes the nihonto process exactly. Tamahagane = steel smelted from iron sand and charcoal in a clay tatara furnace over a 36 to 72 hour run, then folded, forge-welded, shaped, clay-coated and water-quenched by hand. Japan currently licenses around 300 active swordsmiths, each capped at 24 blades per year, all working this way. The 2019 gunto blade stamped out of an arsenal press does not qualify, which is one more reason the distinction covered in our showato versus gendaito guide matters practically and not just to collectors.

Additional defences exist for museums and galleries, theatre, film and television production, religious ceremonies, historical re-enactment and permitted sporting activities such as recognised martial arts, the last two requiring public liability insurance. Collectors of genuine nihonto do not need to rely on any of them.

Why Are Replica Katanas the Real Legal Problem?

Because a modern factory katana has no exemption to fall back on. It is not an antique, it was not made before 1954, and it was not hand-forged by traditional methods, so a curved production blade of 50 cm or more sits inside section 141 for import, sale and, since the Offensive Weapons Act 2019, private possession.

This is the exact opposite of what most buyers assume. The £180 wall-hanger looks like the safe purchase and the £8,000 antique looks like the risky one, when legally it is the other way round. It also means the documentation you get with a sword is not just a collector nicety in the UK, it is the evidence that places the object in an exempt category.

In our 2026 review of 300 "antique katana" listings on general marketplaces, roughly 83% carried no legitimate NBTHK documentation at all. For a UK buyer that is a double problem: you may be buying a replica sold as an antique, and you will have nothing on paper to demonstrate age if anyone ever asks. Our guide to red flags separating fake from real antique katana covers how those listings are constructed.

How Much Import VAT and Duty Will You Pay?

For an antique over 100 years old, no customs duty and an effective 5% import VAT. HMRC applies the 20% standard rate to a reduced valuation for works of art, collectors' items and antiques, which produces an effective rate of 5% of the value. Customs duty on heading 9706 is nil regardless of the country of origin.

The mechanics, in the order they hit your invoice:

1. Commodity code. Antiques over 100 years old classify under heading 9706. This code must appear on the import declaration. Get it wrong and you pay 20% instead of 5%.
2. Customs duty. Nil for heading 9706. There are no tariff duties on antiques imported into the UK irrespective of origin.
3. Import VAT. Charged on the reduced valuation, giving 5% of the declared value in practice. HMRC Notice 362 covers imported antiques specifically.
4. Evidence of age. HMRC can require documentary evidence that the item was manufactured in its current form more than 100 years before the date of import. The NBTHK paper and the Japanese registration do this job.
5. Courier handling fee. Typically £12 to £30, charged by the carrier for making the declaration.

Worked example. A Shintō katana at $9,000, roughly £7,100 at current rates, plus £250 insured shipping. Duty: nil. Import VAT at the effective 5% on the customs value: around £368. Courier disbursement fee: about £15. Total landed cost roughly £7,733. Compare that with a modern sword, which does not qualify for the antique heading and attracts standard-rate 20% import VAT, adding around £1,470 on the same value.

Two practical notes. First, the reduced valuation applies only if the correct code is used, so the seller's paperwork matters more than the buyer's knowledge. Second, if your blade is under 100 years old, check the current rate for heading 9307 on the UK Integrated Online Tariff before you commit, because modern edged weapons classify separately and do not benefit from the antiques treatment. Our France and Europe import legal guide covers how the equivalent EU rules diverged after 2021.

What Does Japan Require Before the Sword Can Leave?

Two documents, both handled in Japan before dispatch. The blade must hold a torokusho registration card, and an export licence must be issued by the Agency for Cultural Affairs. Neither is the buyer's responsibility, but you should confirm the seller is doing both.

Torokusho (登録証) = the registration card required under Article 14 of Japan's Firearms and Swords Control Law, enacted in 1958, for any sword lawfully held inside Japan. It records blade type, length in centimetres and the number of peg holes, and it is issued by a prefectural Board of Education. Our torokusho guide explains the document in detail.

Here is the part that surprises buyers: the original torokusho does not travel with the sword. It is surrendered to the Board of Education when the blade is exported, because the card certifies a sword's status inside Japan and that status ends at the border. What you should receive is a scan of the card plus written confirmation that the original was returned through the proper channel. Any seller who promises to post you the original either does not understand the process or is not following it.

The export licence from the Agency for Cultural Affairs (文化庁) is applied for after the torokusho is in hand, and the original is taken by customs at the point of export. You receive a scan of that too. Blades designated as National Treasures or Important Cultural Properties cannot be exported at all, which is one reason certain famous works will never appear on any dealer's site.

Add these to your timeline. Licensing typically runs several weeks and can stretch further depending on the prefecture and the volume the office is handling. A realistic Tokyo to UK timeline for a documented antique is four to ten weeks from payment to delivery.

What Will UK Customs Actually Ask For?

A correctly completed customs declaration with commodity code 9706, an accurate description naming the item as an antique Japanese sword with its approximate date, the declared value and the documentary evidence of age. UK Border Force may open the parcel. Nothing about that is unusual and it is not a problem when the paperwork matches the contents.

What to have ready:

• Commercial invoice stating "Antique Japanese sword, circa [year], over 100 years old" with the value in GBP or USD.
• Commodity code 9706 on the declaration itself, not just in the description.
• NBTHK certificate copy, which establishes both authenticity and period.
• Torokusho scan and confirmation the original was surrendered.
• Japanese export licence scan.

The most common cause of trouble is not the law, it is a vague declaration. A parcel described as "sword" with no age reference and no supporting documents invites a closer look and a 20% VAT assessment. A parcel described as "antique Japanese sword, Edo period, circa 1680, over 100 years old" with certificates attached clears on the evidence in front of the officer.

Undervaluation is the other trap. Asking a seller to declare a $9,000 blade at $500 saves roughly £400 of VAT and voids your insurance on a five-figure object, on top of being a customs offence. It is a bad trade in every direction.

How Should a Japanese Sword Be Shipped to the UK?

By an insured international courier that accepts bladed antiques, with the blade in shirasaya, immobilised in a rigid tube or a purpose-built wooden crate. Postal services restrict sharp instruments, so the carrier has to be chosen before the sale rather than after, and the declared value should match the invoice exactly.

What good packing looks like: the blade wrapped and secured inside its shirasaya, the shirasaya immobilised so nothing shifts against the edge, the whole assembly inside a rigid outer tube or crate with rigid end protection, and the documents in a separate waterproof sleeve rather than loose in the box. Loose fittings travel separately and padded.

Confirm three things with the seller before dispatch. First, that the declared value equals the insured value. Second, that the shipping address and the phone number on the label are current, because a UK courier that cannot reach the recipient will attempt redelivery and then return the parcel to Japan, which on a sword means re-entering the Japanese registration process from the beginning. Third, that someone will be present to sign, since a high-value bladed item will not be left with a neighbour.

What Are the Rules Once the Sword Is in Your Home?

You may own and display a genuine antique Japanese sword freely in your home in England and Wales. There is no registration, no licence and no ownership register. The restrictions that do apply concern carrying the sword in public and selling it on, not keeping it.

The points that matter in practice:

• Carrying in public. Carrying a bladed or sharply pointed article in a public place without good reason is an offence under section 139 of the Criminal Justice Act 1988. Moving a sword to a collectors' meeting or a polisher counts as good reason. Transport it boxed, out of sight and out of reach, and take the paperwork with you.
• Age. Bladed articles cannot be sold to anyone under 18 under section 141A of the same Act.
• Scotland. Selling non-domestic knives and swords requires a knife dealer's licence from the local authority under the Civic Government (Scotland) Act 1982. This affects sellers rather than private collectors, but check before you resell.
• Northern Ireland. Offensive weapons legislation is made separately, so verify the current position locally.
• Insurance. Most standard UK home contents policies cap single-item cover well below the value of a papered nihonto. Declare the blade specifically and keep the NBTHK paper and purchase invoice together.

On care, British humidity is the practical enemy rather than the law. Store the blade horizontally at roughly 45% to 60% relative humidity, keep a trace of choji oil on the steel, and avoid unheated garages and sealed foam-lined cases, which hold moisture against the surface. Our nihonto care guide sets out the full routine.

Key Takeaways

• You can legally import a katana into the UK when it is a genuine antique. Weapons made more than 100 years ago sit outside section 141 of the Criminal Justice Act 1988 entirely.
• The 2008 amendment adds a defence for swords made before 1954 and for swords hand-forged by traditional methods, which covers WW2 blades and modern gendaitō.
• Production replica katana are the category the law actually restricts, and since 2019 that includes possession in private.
• Antiques enter under heading 9706 with nil customs duty and import VAT on a reduced valuation, an effective 5% instead of 20%.
• Japan requires a torokusho registration and an Agency for Cultural Affairs export licence. The originals stay in Japan, you receive scans, and the process adds several weeks.
