2nd option: Changing Stalin's policies.
The term "de-Stalinization" refers to the political reforms enacted by Nikita Khrushchev.
The reforms eradicated Stalin's influence on the Soviet Union. Khrushchev condemned his predecssor's (Stalin's) actions, and his image as this infalliable leader. Khrushchev promised to revert the Soviet Union back to its self-proclaimed socialist society.
One reason why Japan has such a distinctive culture is because it was closed off from the world from 1623 to 1641. The Tokugawa Shogunate closed Japan because they were afraid of all the new ideas and cultures that came from trading. Because of this period of isolation, Japan created their own unique culture without being influenced by any western ideas.
