Geography
Iyo is situated in the center of Ehime, approximately 10 kilometers southwest of the prefectural capital of Matsuyama. The western portion of the city, from Gunchū in the north down to Futami's Shimonada in the south, hug the coast of the Inland Sea, nestled in the southwestern section of the Dogo Plain. The southeastern portion of the city enters into the mountains in the interior of the prefecture, and the Nakayama area in particular is quite mountainous.
While archaeological artifacts show that the Iyo area has been settled since at least as far back as the Yayoi period, the origins of the present city of Iyo can be traced back to the year 1635, when the Matsuyama han ceded the territory including Iyo to the Ōzu han. The port at Gunchū, the heart of present-day Iyo, became the main commercial port for the Ōzu han and the surrounding community flourished. On January 1, 1955, the town of Gunchū was merged with the villages of Kita-yamasaki, Minami-yamasaki and Minami-iyo to create the first incarnation of the city of Iyo. On April 1, 2005, Iyo absorbed the towns of Nakayama and Futami to create the new and expanded city of Iyo.
Economy
Iyo houses the national headquarters for Marutomo and Yamaki, food manufacturing companies that specialize in dried Bonito flakes. Other main products include mikan and Nakayama chestnuts and other fruits and vegetables. In addition, Futami has had some success in making its sunset a local tourist draw, creating a seaside park, a sunset museum and an annual sunset concert at its Shimonada Station.
The Matsuyama Expressway's Iyo exit provides access to the Matsuyama International Airport and runs through the center of the city, as does Route 56 linking Matsuyama to Ōzu. Route 378, running from downtown Iyo through Futami and towards Nagahama, is a scenic coastal road.
