# Buying a kitchen knife in Japan: where to buy, how to choose, and can you take it on a plane?

> As of October 2026, kitchen knives and petty knives can't go in your carry-on; they must be checked (Japan Ministry of Land, Infrastructure, Transport and Tourism list of restricted items). Choose the blade type first: a santoku (165–180mm) if you're buying just one, a gyuto if you're used to a Western kitchen, then decide between one-piece stainless and Damascus or clad steel depending on how much care you'll give it. Electronics megastores, department store kitchen sections and specialist knife shops all sell them. Some destinations ban certain knife types (the UK bans flick knives and swords, for example), though kitchen knives generally aren't among them; check your destination's rules before you fly.

## The short answer

- **Flying**: kitchen knives, petty knives and gyuto **can't go in your carry-on**; they must be **checked**.
- **Choosing**: buy a santoku if you only want one knife; a gyuto if you prefer a Western chef's knife; add a petty knife for fruit.
- **Care**: one-piece stainless is the easiest; Damascus and clad steel need more care, so dry them after use and don't leave them soaking.
- **Arrival**: kitchen knives can usually come home as personal items, but some places ban certain knife types, so check your destination's rules.

## Choosing a blade type

| Type | Japanese | Typical blade length | Best for |
| --- | --- | --- | --- |
| Santoku | 三徳包丁 | 165–180mm | Vegetables, meat and fish; the one to get if you're buying just one |
| Gyuto | 牛刀 | 180–210mm | Western chef's knife, large cuts of meat, long slicing strokes |
| Petty knife | ペティナイフ | 120–150mm | Fruit and small ingredients, alongside a main knife |

Check the blade length (刃渡り) in the model name or on the box. Longer blades suit large ingredients but take more space, so choose a shorter one for a small kitchen.

## Steel and care

- **One-piece stainless** (blade and handle in one piece): few joints and easy to clean, such as Seki Magoroku Shoso and GLOBAL.
- **Damascus pattern** (layered steel): a layered pattern on the blade, such as Seki Magoroku Damascus and Sakai Takayuki 33-layer.
- **Clad steel (割込, warikomi)**: a hard steel core wrapped in softer steel, such as Tojiro's DP series.

Whether a knife is dishwasher-safe depends on the maker: KAI's official store lists the Seki Magoroku Shoso santoku as dishwasher-safe, while GLOBAL's official guidance recommends hand-washing.

## Where to buy

- **Electronics megastores and department store kitchen sections**: big brands like KAI and GLOBAL are usually in stock, and you can combine them with other tax-free purchases.
- **Specialist knife shops and kitchenware streets**: such as Kappabashi Dougu Street in Tokyo, and the knife-making towns of Seki in Gifu and Sakai in Osaka, with wide selections; some shops engrave names.
- **Prices**: we list the lowest online price on Kakaku.com (excluding shipping); store prices may differ, so go by the actual price tag.

From November 1, 2026, Japan's tax-free system changes to paying tax first and getting a refund after confirmation at departure. You must spend at least 5,000 yen (excluding tax) at the same store on the same day, so one entry-level knife may not be enough; buying it with other items makes the threshold easier to reach. See [Japan's 2026 tax-free changes](/en/q/tax-free-2026/).

## Packing it for the flight

1. **Check it**: knives can only go in checked baggage. Wrap the blade in a sheath or the original box, then pack it between clothes.
2. **Confirm tax-free items before check-in**: tax-free purchases made from November 1, 2026 must be confirmed at the airport tax-free kiosk before you check your bags.
3. **Transfers**: if you have to collect and re-check your bags on a transfer, the knife still can't go in your carry-on.

## What to watch for on arrival

- The UK government says it's illegal to bring listed knives and weapons into the UK, including flick (automatic) knives, butterfly knives, disguised knives and swords; kitchen knives aren't on the banned list. Carrying a knife in public without a good reason is illegal in the UK, so take knives straight home in your luggage.
- We haven't verified other countries' and regions' knife rules yet, so check your destination's customs rules and laws before you travel.
- If knives plus your other purchases abroad exceed your destination's duty-free allowance, declare them; see [duty-free allowances by destination](/en/q/duty-free-allowance-by-country/).

## Frequently asked questions

### Can a knife go in my carry-on if it's still in the box?

No. In the MLIT list of restricted items, kitchen knives are marked × for carry-on and ○ for checked baggage, whether or not the box is sealed. If security finds one, you'll have to give it up or go back to the check-in counter to check it.

### What if my ticket has no checked baggage?

Low-cost carrier base fares often exclude checked baggage, so add it before you buy a knife. You can also have the store or an international courier ship it home; whether it can be shipped and how much it costs depends on the courier's rules.

### Can I put it in the dishwasher?

Follow the maker's guidance. KAI's official store lists the Seki Magoroku Shoso santoku as dishwasher-safe, while GLOBAL's official guidance says a dishwasher can cause rust and recommends hand-washing with mild detergent. If the maker doesn't say, hand-wash to be safe.
