Self-heating meals on flights in and from Japan

The rule for self-heating meals comes from the Civil Aviation Bureau's list of restricted items and is the same on domestic and international flights.

Heating agents, MREs and ration heaters: how each list words it

Few lists name this item, and the ones that do use different words for it.

The heating agent is what Japan's entry names
Japan's list of restricted items gives this entry among its examples of dangerous goods, marked as refused in the cabin and in checked baggage. The words in brackets carry the meaning: a bento with a heating agent, a drink with a heating agent. A boxed meal with no heating agent is not in that entry and is judged as ordinary food.
What sits beside it on the list
The row directly above it refuses oil-filled pocket warmers and platinum (hakkin) warmers in the cabin and in checked baggage, just like the self-heating bento. Neither row carries a quantity figure, so the size of the pack and the bag it travels in make no difference.
The list's note on safety data sheets
Japan's list opens with a note that covers every dangerous goods example on it. An item shown as an example can be carried without restriction when a safety data sheet (SDS) or a document issued by the maker shows it is not dangerous goods. On whether a product counts as dangerous goods, the list tells passengers to ask the airline, which may apply stricter rules of its own.

Each row comes from that authority's own page. Airlines can be stricter, and the screening officer has the final say.

If security in Japan will not let self-heating meals through

What to do
Self-heating meals cannot go in checked baggage either. Leave them behind or hand them to someone who is not flying. Narita Airport states that anything given up at the checkpoint is discarded and cannot be returned.
If it gets on board
Taking an item that is restricted from the cabin onto an aircraft is punishable under Japan's Civil Aeronautics Act: up to 2 years' imprisonment or a fine of up to 1,000,000 yen.
