Can you bring paint on a plane?

In Japan paint and thinner cannot go on a plane at all, in carry-on or checked bags. Carry-on: No. House paint, thinner and varnish are not allowed, and paint sprays are banned from both bags. Artists' paints are the exception: Japan's liquids list names watercolours, and Narita Airport accepts oil paints, in containers of 100ml or less in the liquids bag on international flights. Checked baggage: No for house paint, thinner and varnish. Artists' oil paints can be checked; the thinning oil cannot.

Paint and thinner on flights in and from Japan

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

Paint and thinner: carry-on and checked baggage in Japan
WhereAllowed?What applies
In the cabinNoNo. House paint, thinner and varnish are not allowed, and paint sprays are banned from both bags. Artists' paints are the exception: Japan's liquids list names watercolours, and Narita Airport accepts oil paints, in containers of 100ml or less in the liquids bag on international flights. The oil used to thin oil paints is banned.
In checked baggageNoNo for house paint, thinner and varnish. Artists' oil paints can be checked; the thinning oil cannot.

Narita Airport adds that paints of some colours fall within the goods prohibited from transport, and tells passengers to confirm with the airline.

Narita AirportNarita says oil paints follow the liquid rule on international flights (100 ml containers in a 1-litre bag, otherwise checked), but the oil for dissolving them is a dangerous good banned from carry-on and checked baggage.Narita International Airport FAQ

Watercolours, oil paints, spray cans and thinner are separate cases

Japan's list says no to paint, but other Japanese documents name paints that can fly and sprays that never can.

Watercolours and ink count as ordinary liquids
Japan's liquids list for international flights names Watercolors, and the Japanese version puts them in the same line as correction fluid, fountain-pen ink and sumi ink. They may be taken into the cabin in containers of 100 ml or less inside the 1 litre bag. The × × row for paint belongs to the separate list of dangerous goods.
Spray paint is refused in both bags
The same liquids list has a short group of aerosols that cannot travel at all, and Paint sprays head it; the Japanese version adds sprays for model kits. The TSA marks Spray Paint No for carry-on and No for checked bags, CASA flags it Item Not Permitted, and Hong Kong's CAD forbids aerosol paint and spray paint.
Some oil colours are barred, Narita says
Narita Airport's answer on artists' oil paints carries one more caution: paints of some types of colours fall within the scope of goods prohibited from transport, and it tells passengers to confirm with their airline. It does not say which colours. Japan's list has one pigment rule of its own: luminous paint is allowed only as the paint on a watch and is × × otherwise.
Flammable or not: the test in Hong Kong and Australia
In Hong Kong and Australia the dividing line is flammability. Hong Kong's CAD says manufacturers may indicate on the packaging whether a product is flammable, toxic, corrosive or hazardous, and to consult them if in doubt. CASA sorts artists' paint into non-flammable kinds that may fly and flammable kinds that may not, and files linseed oil with the non-flammable ones.
A finished painting is not paint
A dry, finished painting is a different item. The TSA has an entry for Paintings, marked Yes for carry-on and Yes for checked bags, and another for Printer Ink with the same answers. On Japan's list the cosmetic relatives of paint, nail polish and nail polish remover, sit in the toiletries table and are allowed within its quantity limits.

If security in Japan will not let paint and thinner through

What to do
Paint and thinner 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.
