Until the Meiji Restoration, Ehime Prefecture was known as Iyo Province. Since before the Heian period, the area was dominated by fishermen and sailors who played an important role in defending Japan against pirates and Mongolian invasions.
After the Battle of Sekigahara, the Tokugawa shà Âgun gave the area to his allies, including Katà  Yoshiaki who built Matsuyama Castle, forming the basis for the modern city of Matsuyama.
The name Ehime comes from the kuniumi part of the Kojiki where Iyo Province is mythologically named Ehime, "lovely princess".
In 2012, a research group from the University of Tokyo and Ehime University said they had discovered rare earth deposits in Matsuyama.
