Ehime Prefecture (愛媛県, Ehime-ken) is a prefecture of Japan located on the island of Shikoku. [3] 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 Kōchi Prefecture to the southeast.


Matsuyama is the capital and largest city of Ehime Prefecture and the largest city on Shikoku, with other major cities including Imabari, Niihama, and Saijō. [4]


Until the Meiji Restoration, Ehime Prefecture was known as Iyo Province. [5] 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 shōgun gave the area to his allies, including Katō 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". [6]

In 2012, a research group from the University of Tokyo and Ehime University said they had discovered rare earth deposits in Matsuyama. [7]


Located in the northwestern part of Shikoku, Ehime faces the Seto Inland Sea to the north and is bordered by Kagawa and Tokushima in the east and Kōchi in the south.

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 31 March 2020, 7 percent 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 Hijikawa, Kinshako, Okudōgo Tamagawa, Sadamisaki Hantō-Uwakai, Saragamine Renpō, Sasayama, and Shikoku Karst Prefectural Natural Parks.
