- The Thirty-Six Female Immortals of Poetry: ''Nyōbō Sanjūrokkasen'' (女房三十六歌仙) , composed in the Kamakura period, refers to thirty-six female immortals of poetry: Ono no Komachi Ise Nakatsukasa Kishi Joō Ukon Fujiwara no Michitsuna no Haha Uma no Naishi Akazome Emon Izumi Shikibu Kodai no Kimi Murasaki Shikibu Koshikibu no Naishi Ise no Taifu Sei Shōnagon Daini no Sanmi Takashina no Kishi Yūshi Naishinnō-ke no Kii Sagami Shikishi Naishinnō Kunai-kyō Suō no Naishi Fujiwara no Toshinari no Musume Taikenmon'in no Horikawa Gishūmon'in no Tango Kayōmon'in no Echizen Nijō In no Sanuki Kojijū Go-Toba-in no Shimotsuke Ben no Naiji Go-Fukakusa In no Shōshōnaishi Inpumon'in no Tayū Tsuchimikado In no Kosaishō Hachijō-in Takakura Fujiwara no Chikako Shikikenmon'in no Mikushige Sōhekimon'in no Shōshō
