I have a friend from my school that hates communism and communists and he is aware that I listen to J-Pop (Japanese pop) and 2 months ago, he warned me that Japan is a communist country and it held a communist party in 1922
an economic ideology that advocates for a classless society in which all property and wealth are communally owned instead of being owned by individuals (according to Google search)
Japan is not a communist country, it has a capitalist government partly based off the U.S government, it does have a communist party with seats in parliament, but it is not a governing party and capitalist policies remain in place.
