A widowed nun rode from Kyoto to Kamakura in 1279 to sue her stepson for her son's estate, and her son's family still owns the archive she fought for

Fujiwara no Tameie headed the Mikohidari house of court poets, heir to his father Fujiwara no Teika. Around 1252 he took as his late partner a lady-in-waiting known later as the nun Abutsu. They had three sons, including Tamesuke, born in 1263. In his old age Tameie gave Tamesuke the Hosokawa estate in Harima province and the family's poetry documents. His eldest son, Tameuji, by an earlier wife, disputed the transfer. Abutsu moved the house's inherited manuscripts to her own residence. Tameie died in 1275. On the 16th day of the 10th month of 1279 Abutsu left Kyoto for Kamakura to bring the case before the shogunate's court. Her diary of the journey and her stay became the Izayoi Nikki, named for the moon of that night. It ends with a long poem praying at Tsurugaoka Hachimangū for the case. She died in the 4th month of 1283 before judgment. She has graves in both Kyoto and Kamakura. The suit was eventually decided in Tamesuke's favour. He founded the Reizei house, which kept the documents for about 800 years, including Teika's own diary, the Meigetsuki. Since 1981 they have been held by the Reizei-ke Shiguretei Bunko foundation in the family's Kyoto house, designated an Important Cultural Property in 1982.
