Saiin (priestess)

Saiin or Itsuki no In (斎院) were female relatives of the Japanese emperor (termed saiō) who served as High Priestesses in Kamo shrines. Saiin princesses were usually elected from royalty (内親王, naishinnō) or princess (女王, joō). In principle, Saiin remained unmarried, but there were exceptions. Some Saiin became consorts of the Emperor, called Nyōgo in Japanese. The Saiin order of priestesses existed throughout the Heian and Kamakura periods.

Saiin is also the name given to the palace where the Saiin Priestesses lived and served the Shinto deities.

Saiin in Literature
In The Tale of Genji, a famous work of Japanese literature, there is a story about a man named Hikaru Genji who yearned for a Saiin Princess named Asagao, but Asagao maintained a platonic relationship with Genji.

The 11th century story Sagoromo Monogatari tells the story of an unrequited love between the protagonist and Genji no Miya, who later becomes the Kamo Saiin.

Princess Shikishi (式子内親王)
Princess Shikishi (Shikishi Naishinnō), 3rd daughter of Emperor Go-Shirikawa and Fujiwara no Seishi, was appointed High Priestess of Kamo shrine in 1159, at the age of six. She resigned her position in 1169 due to illness. After her resignation Shikishi went on to become an accomplished poet. 399 of her poems remain in existence today.
