Four Heavenly Kings (四天王, Shiten'nō?), also called Yorimitsu's Four Heavenly Kings (頼光四天王, Yorimitsu Shiten'nō?), was a group of samurai that operated in Japan during the Heian Period. Their leader was Minamoto no Raikou.
The Four Heavenly Kings was established by Minamoto no Raikou, and consisted of his four retainers, with the duty to protect the imperial capital from all possible threats. Their most famous conflict was the battle against the many Oni of Mt. Ooe, which included Shuten-douji and Ibaraki-douji.
