What happened
Buddhism was introduced into Japan in either 538 or 552 CE, by traditional dating, arriving from the Korean kingdom of Baekje rather than directly from China or India. It received official government support in 587 CE under Emperor Yomei, and its most influential early champion was Prince Shotoku (574-622 CE), who ruled Japan as regent from 594 CE until his death. Shotoku wrote a Seventeen Article Constitution in 604 CE that built Buddhist principles into Japanese governance, and built 46 Buddhist monasteries and temples during his reign, including the still-standing Horyuji. Later Chinese contact deepened Japan's exposure to Buddhist variety: the monk Saicho visited Tang China in 804 CE and studied several branches of Buddhism, including Zen and Tiantai, bringing that range of practice back to Japan.
Why it matters
Buddhism's arrival by way of Korea rather than direct transmission from India or China shows how the religion moved through relay, absorbed and reshaped at each stop before being passed further on, and Prince Shotoku's decision to build Buddhist principles directly into a foundational constitutional document made Japan one of the few places where Buddhism became explicit state doctrine this early.
How we know
Buddhism's introduction to Japan and Prince Shotoku's patronage are documented in early Japanese court chronicles and corroborated by surviving physical evidence, including Horyuji temple itself, still standing among the world's oldest wooden buildings.
