Step-by-step explanation:
Nichiren Daishonin, a Buddhist monk and philosopher, was exiled and executed in Japan during the Kamakura period in the 13th century. He was exiled to the remote island of Sado due to his rebellious teachings and criticism of the ruling class.
While in exile, he continued to spread his teachings and gained many followers. Eventually, he was pardoned and returned to the mainland, but he faced opposition from other Buddhist sects who viewed his teachings as heretical. He was later executed in 1282.
