Can you take snacks on a plane? Rules by country

Snacks on flights in and from Japan

The rule for snacks comes from the Civil Aviation Bureau's list of restricted items. On international flights its liquids list applies as well.

Snacks and sweets: carry-on and checked baggage in Japan
Where	Allowed?	What applies
In the cabin	Yes	Yes, in any quantity. Candies, chocolate, cookies, cakes and doughnuts are not treated as liquids. Pudding, milk shakes, smoothies and ice cream are: on international flights they fall under the 100ml liquid limit.
In checked baggage	Yes	Yes.

Airport security is only half of it. Snacks that contain meat, such as jerky or meat floss, cannot be brought into Japan at all.

Daifuku, dorayaki, pudding: which sweets count as liquids

Japan's list sorts sweets by form. Candies, cookies, cakes and Japanese sweets such as daifuku are on the unrestricted side, and a group of desserts is not.

Souvenir sweets named as unrestricted: The Japanese-language edition of Japan's liquids list spells out its confectionery row at length. It names rice crackers, potato chips, popcorn, chewing gum and caramel, fresh sweets such as dango, daifuku, ohagi and cream puffs, and half-fresh sweets such as dorayaki, manju, monaka, castella and baumkuchen. All of them sit outside the liquid restriction on international flights.
Desserts on the restricted side: The dessert and yogurt row is where the line falls. Besides pudding it lists jelly, mousse, bavarois, mitsumame, anmitsu, oshiruko, zenzai, annin tofu and kuzukiri, and the ice cream row adds shaved ice. In carry-on on an international flight these need containers of 100 ml or less. Mizu-yokan, by contrast, is named in the unrestricted confectionery row.
Bean paste and honey sold on their own: A filling is judged differently once it is packed by itself. The row for confectionery ingredients restricts honey, starch syrup and bean paste that come canned, jarred or in plastic containers or tubes. The Japanese-language edition adds gum syrup, cake syrup and smooth bean paste (koshi-an). Finished sweets such as manju and daifuku stay in the unrestricted row.
Fresh sweets kept cold with dry ice: Narita's FAQ answers a traveller taking fresh sweets abroad as a gift. Dry ice may go in both carry-on and checked baggage for the purpose of cooling perishable food including fresh sweets, up to 2.5 kg per person in principle, and airlines may set different limits or require labelling.

Frequently asked questions

Can you take snacks on a plane?

On flights in and from Japan: Yes, in any quantity. Candies, chocolate, cookies, cakes and doughnuts are not treated as liquids. Pudding, milk shakes, smoothies and ice cream are: on international flights they fall under the 100ml liquid limit. In checked baggage: Yes.

Do you have to take snacks out of your bag at airport security?

Not under Japan's liquids list. It says the unrestricted items, confectionery among them, do not have to be offered to the screener at the security checkpoint, whatever the quantity. In the US the TSA says officers may instruct travelers to separate foods from carry-on bags, because they can clutter the bag and obstruct clear images on the X-ray machine.

Can you bring chocolate on a plane in your carry-on?

Yes, when it is solid. Japan's liquids list names chocolate in its unrestricted confectionery row, while the Japanese-language edition puts chocolate cream and custard cream in the spreads row with peanut butter. The TSA draws the same line with a pair of entries: Chocolate (Solid) is allowed in carry-on, and Chocolate (liquid) is limited to 3.4oz/100 ml.

Snacks and candy are solid food and are allowed in carry-on and checked bags. Liquid or gel food items larger than 3.4 oz are not allowed in carry-on bags.
