# Can I take outdoor gear bought in Japan on a plane? What about gas canisters, knives, trekking poles and power banks?

> According to the Japan Ministry of Land, Infrastructure, Transport and Tourism (MLIT) list of restricted items (as of October 2026), stove gas canisters (screw-on OD canisters and cassette CB canisters) are banned in both carry-on and checked baggage. Knives, multi-tools and trekking poles can't go in the cabin and must be checked, while power banks must be carried on and never checked; those up to 100Wh generally need no approval, and since April 2026 Japan limits each passenger to two and bans charging them or charging from them on board. A stove burner with no fuel left can go in carry-on or checked baggage, but airlines may be stricter, so check your airline's notices before you fly.

## Gas canisters: the most common wasted purchase

Whether it's a Snow Peak or JETBOIL screw-on canister or a cassette stove canister from a convenience store, it's banned in both carry-on and checked baggage. If you camp in Japan, buy canisters locally and use them up. You can take a stove burner home and buy canisters there, but mind the connection type: the SOTO ST-310 uses cassette (CB) canisters, and the Snow Peak GigaPower uses screw-on (OD) canisters.

## Knives and trekking poles: remember to check them

Japan doesn't allow knives or trekking poles in the cabin. If you're flying home with only a carry-on bag, or your budget airline ticket has no checked bag allowance, think twice before buying. If you're connecting, also check the rules at your transit airport.

## Power banks and battery lanterns

- Carry-on only; never put them in checked baggage.
- Up to 100Wh generally needs no approval. A 10,000mAh power bank is usually under 40Wh, but go by the rating printed on the device.
- Since April 2026, Japan limits each passenger to two power banks and bans charging a power bank on board or using it to charge your phone.
- Lanterns that can charge a phone, such as the mont-bell Power Bank Lantern (パワーバンク ランタン), count as power banks.
- If you connect to a domestic flight within mainland China, the Civil Aviation Administration of China requires power banks to have CCC (3C) certification, which ones bought in Japan usually lack. Check in advance. See [Lithium battery rules for flights](/en/q/lithium-battery-flight/).

## Arriving home

Outdoor gear can be expensive, so check your own country's duty-free allowance before you buy. (For mainland China, purchases over 5,000 yuan must be declared; see [the 5,000-yuan rule](/en/q/china-customs-5000/).) Flight tips for specific models are on the [outdoor gear category page](/en/c/outdoor/).
