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.
The name Ehime comes from the Kojiki and means "beautiful maiden."
In 2012, a research group from the University of Tokyo and Ehime University said they had discovered rare earth deposits in the City of Matsuyama in Ehime-ken.
The prefecture includes both high mountains in the inland region and a long coastline, with many islands in the Seto Inland Sea. The westernmost arm of Ehime, the Sadamisaki Peninsula, is the narrowest peninsula in Japan.
As of 1 April 2012, 7% of the total land area of the prefecture was designated as Natural Parks, namely the Ashizuri-Uwakai and Setonaikai National Parks; Ishizuchi Quasi-National Park; and seven Prefectural Natural Parks.
Eleven cities are located in Ehime Prefecture:

The area around Matsuyama has a number of industries, including shipbuilding, chemicals, oil refining, and paper and textile products.
