Can I take dry ice on a plane in Japan?

You can take this in the cabin, but there are conditions. Up to 2.5kg per person, and only if it is cooling something that is not itself dangerous. The container must let the gas escape. In checked baggage: same limit. Tell the airline at check-in.

What the rule says

Japan follows the international rules on dangerous goods, set out by the Civil Aviation Bureau.

Dry ice: carry-on and checked baggage
Where	Allowed?	What applies
In the cabin	Yes, within limits	Up to 2.5kg per person, and only if it is cooling something that is not itself dangerous. The container must let the gas escape.
In checked baggage	Conditions	Same limit. Tell the airline at check-in.

Before you get to the checkpoint

Airlines can be stricter than the national rule. If it matters to your trip, check your airline's own page.
If an item is refused at the checkpoint you cannot go back and check it in — you lose it.
Japanese security staff will ask before opening your bag, and most speak enough English for this.

Why the rule is what it is

The limit is about the liquid, not the food.

If it is refused: You cannot go back and check it in once you are at the screening point. It is taken from you and disposed of, and there is no compensation. Some Japanese airports have a post counter before security where you can mail it to yourself.
Who decides: The officer at the checkpoint, applying the national rules and your airline's own conditions. Where the airline is stricter, the airline wins.

Food and drink on a flight to Japan

Airport security rarely stops food. The Japanese border does.

On the plane, food is only a problem when it is a liquid or has a heat source in it. Sauces, soups and yoghurt count as liquids on international flights.
At the Japanese border the rules change completely: anything containing meat is banned, and so is most fresh fruit and veg.
Eat your in-flight meal on board. Taking a sandwich or cut fruit off the plane counts as bringing it into Japan.
Packaged snacks, biscuits, chocolate and instant noodles without meat are all fine.
