Kira Tsuneie
Kira Tsuneie was a warrior of the Kamakura period (1185–1333) and the third head of the Oshu, or Musashi, branch of the Kira clan, the early Tojo Kira. A note in the Sonpi Bunmyaku gives him the style Fujitani; he is said to have held the Fujitani estate in Adachi district of Mutsu province and taken the Fujitani name.
Tradition also credits him with building Yotsuhongamatsu Castle there, but the estate's location is unknown and the story is unconfirmed, perhaps confused with his son Sadaie, the powerful Oshu kanrei.
