Ehime Prefecture (愛媛県, Ehime-ken) is a prefecture of Japan located on the island of Shikoku.  Ehime Prefecture has a population of 1,342,011 (1 June 2019) and has a geographic area of 5,676 km² (2,191 sq mi). Ehime Prefecture borders Kagawa Prefecture to the northeast, Tokushima Prefecture to the east, and Kochi Prefecture to the southeast.
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.
In 2012, a research group from the University of Tokyo and Ehime University said they had discovered rare earth deposits in Matsuyama. 
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 April 1, 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:
These are the towns in each district:
The coastal areas around Imabari and Saijō host a number of industries, including dockyards of Japan's largest shipbuilder, Imabari Shipbuilding. Chemical industries, oil refining, paper and cotton textile products also are a feature of the prefecture. Rural areas mostly engage in agricultural and fishing industries, and are particularly known for citrus fruits such as mikan ( mandarin orange), iyokan and cultured pearls.
