Ehime: The Japanese Prefecture Named After a Lovely Princess
In short: Located on the island of Shikoku, Ehime Prefecture is a region defined by its deep maritime history, industrial prowess, and ancient traditions. From the oldest hot springs in Japan to the birthplace of Nobel laureates, this prefecture balances a rugged, mountainous landscape with a long, storied coastline.
Historically known as Iyo Province until the Meiji Restoration, the region derives its modern name from the Kojiki, where it is mythologically referred to as Ehime, meaning lovely princess. Long before modern development, the area was a stronghold for fishermen and sailors who were instrumental in defending Japan against pirates and various invasions. Following the Battle of Sekigahara, the Tokugawa shōgun granted the territory to his allies, including Katō Yoshiaki, who constructed Matsuyama Castle, the foundation for the prefecture's capital city.
Today, Ehime is a hub of both heavy industry and natural beauty. The coastal regions around Imabari and Saijō are home to major dockyards, including those of Japan's largest shipbuilder, Imabari Shipbuilding, alongside chemical and textile industries. The prefecture also plays a critical role in energy production through the Ikata Nuclear Power Plant. Beyond industry, the region is celebrated for its agricultural output, particularly citrus fruits like mikan and iyokan, as well as its cultured pearls.
The prefecture is perhaps best known for its cultural depth. It hosts Dōgo Onsen, the oldest extant hot spring in Japan, which has been in use for over two thousand years and is mentioned in the Nihon Shoki. The region has also produced three Nobel Prize winners: Kenzaburo Oe, Shuji Nakamura, and Syukuro Manabe. With a geography ranging from the narrow Sadamisaki Peninsula to high inland mountains, Ehime continues to blend its ancient heritage with modern international engagement, including hosting the Velo-city conference in 2027.
