Lady Nijō

Lady Nijō (後深草院二条, Go-Fukakusain no Nijō) was a Japanese noblewoman and diarist. She was a concubine of Emperor Go-Fukakusa from 1271 to 1283, and later became a Buddhist nun. After years of travelling, around 1304–07 she wrote a memoir, Towazugatari ("An Unasked-For Tale", commonly translated into English as [The Confessions][1] of Lady Nijō), the work for which she is known today, and which is also the only substantial source of information on her life.
