What the rule says

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

Aerosol cans (general): carry-on and checked baggage
Where	Allowed?	What applies
In the cabin	Yes	Depends what is in it. Cosmetic, medicinal and household aerosols: 0.5 litres or 0.5kg per can, 2 litres or 2kg per person in total, nozzle protected. Anything flammable or toxic beyond that: no.
In checked baggage	Conditions	Same limits.

What that means in practice

The 2 litre allowance is shared between cosmetics, medicines and aerosols together.

Before you get to the checkpoint

On an international flight every container of liquid must be 100ml or less, inside one transparent re-sealable bag of 1 litre or less.
Domestic flights inside Japan have no liquid limit at all.
Medicine, baby milk and special dietary food are exempt — carry them separately and tell the officer.
Take the bag out of your luggage and put it in its own tray.

Why the rule is what it is

It is neither dangerous goods nor something that could be used as a weapon, so neither rule applies to it.

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.

You can buy this in Japan

Where to buy it: Drugstores and hundred-yen shops

Worth weighing against the space it takes in your bag. Most of this is cheaper in Japan than the excess baggage fee, and hundred-yen shops carry the everyday version of almost everything.

What makes an aerosol acceptable

The gas inside and the cap on the nozzle decide it.

Cosmetic, medicinal and household aerosols: 0.5 litres or 0.5kg per can, 2 litres or 2kg per person, shared with cosmetics and medicines.
The nozzle must be capped or protected so it cannot be pressed by accident.
Flammable and toxic gas is refused outright — camping gas, fumigators, pepper spray.
Bleach, mould remover and anything labelled chlorine-based cannot travel in either bag.
