Hoshunin, the birth mother of the lord of the Sendai Clan, DATE Masamune, is the daughter of MOGAMI Yoshimori, the lord of Yamagata Castle (Yamagata Prefecture), and the sister of MOGAMI Yoshiaki.
She married DATE Terumune who was the lord of Yonezawa Castle (Yamagata Prefecture) and had their first son Masamune (Bontenmaru) and their second son Kojiro (Sakumaru).
After the death of Terumune, she became a buddhist nun in her mourning and changed her name to Hoshunin.
Hoshunin paricularly loved her younger son Kojiro.
She attempted to poison Masamune in 1590 to support Kojiro but failed.
Masamune defeated Kojiro and then Hoshunin left for her parents' house in Yamagata.
Even after this incident, Masamune continued to have written correspondence with Hoshunin, and when her lands were confiscated due to the Mogami clan's succession conflict, Masamune welcomed her to Sendai.
In 1623, Masamune was informed of Hoshunin's death in Kyoto.
