Khan Academy: Buddhism in Japan

Buddhism was officially transmitted to Japan in 525, when the monarch of the Korean kingdom of Baekje sent a mission to Japan with gifts, including an image of the Buddha, several ritual objects, and sacred texts. Buddhism's journey from India to China, Korea, and Japan had taken about a thousand years. The arrival of Buddhism created political struggles between pro- and anti- Buddhist groups. Eventually, the adherents of Buddhism prevailed, and the new religion became firmly established under imperial sponsorship.
