Mogami clan

The Mogami kamon.

The Mogami of Dewa Province were descended from the Shiba family and were founded by Shiba Iekane's son Kaneyori; the Mogami increased their influence during the Sengoku Period and reached their peak after the Battle of Sekigahara; they were, however, to lose much of their wealth and influence due to the poor administration of Mogami Yoshitoshi in the early Edo Period.
