Ehime has the fifth longest coastline in Japan, measuring over 1,625 km. 
The prefecture stretches from northeast to southwest, with industry 
concentrated on the east coast. The center, including Matsuyama, serves 
as the political and economic base, with fruit cultivation and marine 
products industries concentrated in the south. In Japan, Ehime is the 
largest producer of citrus fruit, such as the mandarin orange, and is 
also a leading producer of pearls and fish. Ehime utilizes its 
environmental characteristics to give its industries a unique status.
