Japan's isolationist policy during the Edo period limited contact with the outside world but allowed for the development of unique cultural practices and traditions.

Neon Genesis Evangelion, created by Hideaki Anno in 1995, is a popular anime series that explores themes of psychology, philosophy, and spirituality, and has become a cult classic.

Karate, another martial art that originated in Japan, has also become a popular sport and is practiced by millions of people around the world.
