Aren't Japan and China very similar? They are all societies where the group is valued as more important than the individual.
I would say Chinese society values the family… people don’t really give a shit about others outside of family or friends.
My feeling on Japan is that they value their society and country much higher.
But I’m neither Chinese nor Japanese so take that with a grain of salt.
I would estimate that Japanese differ from Chinese to a similar degree that Russians differ from Spaniards.
