Buddhist monk Kyokai, also known as Kyokai or Kyōkai, was an influential figure in Japanese Buddhism during the Heian period (794-1185). He was a disciple of the renowned Buddhist monk Jikaku Daishi (Ennin) and played a vital role in the propagation of Buddhism in Japan. Kyokai is credited with compiling "Nihon Ryouiki" to preserve and disseminate Buddhist teachings and stories in Japan. His work reflects a blend of Buddhist principles with indigenous Japanese beliefs and folklore, making it a valuable source for understanding the cultural and religious landscape of Japan during that period. Kyokai's efforts were instrumental in bridging the gap between Buddhism and native traditions, contributing to the enrichment and diversification of Japanese religious practices during the Heian period.
