Prince Shotoku (February 7, 572 – April 8, 622), also known as Prince Umayado or Prince Kamitsumiya, is a semi-legendary regent and a politician of the Asuka period in Japan who serves under Empress Suiko.

He is a son of Emperor Yomei and his younger half-sister Princess Anahobe no Hashihito.

The primary source of the life and accomplishments of Prince Shōtoku comes from the Nihon Shoki.

Over successive generations, a devotional cult arises around the figure of Prince Shotoku for the protection of Japan, the Imperial Family, and for Buddhism.

Key religious figures such as Saicho, Shinran and others claimed inspiration or visions attributed to Prince Shotoku.
