Geography

Shikokuchūō is located in eastern Ehime Prefecture, with the Hoō Mountains to the south and the Gulf of Hiuchi of the Seto Inland Sea to the north. Because the plains are narrow, a local wind called "Yamaji" blows down from the mountains toward the sea. To the south of the Hoō Mountains, the Douzan River, one of the Yoshino River's tributaries, flows eastward, and further south are the Shikoku Mountains, which forms the border with Kōchi Prefecture. The Japan Median Tectonic Line runs east-west along the foot of the Hoō Mountains. The city is located 60 kilometers from Kōchi city, 70 kilometers from Takamatsu, 80 kilometers from Matsuyama, Ehime and 100 kilometers from Tokushima.

History

The area of Shikokuchūō was part of ancient Iyo Province. Ruins found within the city limits suggest that the area was first inhabited more than 12,000 years ago. People first lived in the hilly areas along the Kinugawa River, and then spread to the coastal plains from the Jomon period to the Yayoi period. In the middle of the Kofun period, Toguyama Kofun, which is said to be the tomb of Prince Kinashi Karu, was constructed. In the late Kofun period, in the 6th century, burial mounds began to be built in hilly areas. In the first half of the 7th century, the Umamukaiyama Kofun, which has one of the largest stone burial chambers in Shikoku, was built. After the Nara period Taika Reforms, this area came to be called Uma District. The city limits of Uma District and modern Shikokuchūō are almost the same. As Uma is centrally located in Shikoku, it was historically a transportation hub between Shikoku's major cities. Due to its strategic importance, during the Sengoku period Uma was repeatedly invaded by the neighboring warlords.^[7] During the Edo Period, the area as divided between the holdings of Imabari Domain, Saijō Domain and tenryō territory administered on behalf of the Tokugawa shogunate by Iyo-Matsuyama Domain. Industry began to flourish in Uma during the Edo period, and the city grew as a port town. The Tosa kaidō offered access to Tosa Province in the south, so Uma was also a stopping spot, or ‘post station,’ for the Tosa daimyō and travelers to and from Tosa.^[8] Paper making began in Uma around 1750,^[7] and much later grew into the region's major industry.

Following the Meiji restoration, the area was divided into 25 villages with the establishment of the modern municipalities system on December 15, 1889. The villages of Mishima and Kawanoe were raised to town status in 1898. The village of Doi was raised to town status in 1954 and the villages of Shinritsu and Kamiyama merged to form the village of Shingū the same year. Late that year, Kawanoe and Mishima were raised to city status, with Mishima renamed Iyomishima.

Shikokuchūō city was founded on April 1, 2004 when the cities of Kawanoe, Iyomishima, the town of Doi and the village of Shingū merged. The name literally means "Shikoku Central City" and was so named in the hopes of becoming the new capital of the island of Shikoku, should the four prefectures be merged into one state. ^{[citation needed]} However, this name has been roundly criticized for its unoriginality, and is known as one of the "strange city names" throughout Japan. ^{[citation needed]}

The former cities of Kawanoe and Iyomishima (the two largest of the four municipalities that merged) have fought for political control over the new city. ^{[citation needed]}

Government

Shikokuchūō has a mayor-council form of government with a directly elected mayor and a unicameral city council of 22 members. Shikokuchūō contributes three members to the Ehime Prefectural Assembly. In terms of national politics, the town is part of Ehime 3rd district of the lower house of the Diet of Japan.

Economy

Shikokuchūō is one of the major industrial cities in the Ehime and Shikoku regions, and is one of Japan's leading paper manufacturing areas.^[2]

Paper industry

The history of the paper industry in Shikokuchūō extends back to around 1750, when washi was first produced in the Uma area.^[7] The area does not have much flat land, and is ill-suited to rice farming, but as water and paper mulberry (kōzo) are plentiful, it is ideal for paper manufacturing.^[9] The modern paper industry began to flourish when mechanized manufacturing techniques were developed in the Meiji era. After World War II, the paper industry contributed to the city's rapid economic growth.

The city paper museum, Kami no Machi Shiryokan, has exhibits and information on traditional paper making and the modern paper industry.

Education

Shikokuchūō has 18 public elementary schools and six public middle schools and one combined public elementary/middle school operated by the city government. The city has three public high schools operated by the Ehime Prefectural Board of Education.

Local attractions

Junshin-do

The Buddhist monk Junshin dwelt here after he was expelled from Tosa province (modern day Kochi). As is described in the lyrics of the Yosakoi naruko dancing song, Junshin had an illicit affair with a comb-maker's daughter, and the two of them attempted to elope. After they were caught leaving Tosa without permission, Junshin was permanently expelled from Tosa, and the two of them were separated. Junshin lived in this building for the remainder of his life. ^{[citation needed]}

Kawanoe Castle

Kawanoe Castle was built in 1337 at the beginning of the Nanboku-cho period. For the next several hundred years, it was attacked repeatedly by armies from Sanuki, Awa, and Tosa. It fell to the armies of Toyotomi Hideyoshi in 1585, when he conquered Shikoku. The castle was torn down in 1611, and some of it was used for Matsuyama Castle. In 1984, Kawanoe City began a project to rebuild Kawanoe Castle. Construction was completed in 1988.^[10]

Kofun

Many burial mounds, or kofun, were built in the area during the mid to late Kofun period. These include the Toguzan burial mounds, the Kyogaoka burial mounds (circa sixth century AD), and the Umamukaiyama Kofun (early seventh century).^[7] The Toguzan kofun is said to be the grave of crown prince Kinashi no Karu no Miko,^{[citation needed]} son of the nineteenth emperor, who in the Kojiki was banished to Iyo by his brother.

Manabe house

The Manabe house is the oldest extant minka (traditional Japanese house) in Ehime, and is designated as a national cultural treasure. The house was built by the Manabe family, who were descended from members of the Heike clan who fled to Shikoku after the Heike's defeat in the Genpei War. ^{[citation needed]}

Tosa Kaidō

The Tosa Kaidō is a direct route over the mountains between Tosa (modern day Kochi) and Iyo (modern day Ehime) that was used from ancient times to the Edo era. In Shikokuchūō, the road starts in Kawanoe, passes through Shingu, and continues to Sasagamine ridge in Otoyo Town, Kochi. Parts of the road date back to 793, when it was made an official government route of the Daijo-kan (the central government in Kyoto).^[11] The road later fell out of use by the government, but continued to be used by travelers and people in Shikoku for the next nine hundred years. From 1718, the Edo shogunate began to use the road for sankinkotai, the policy of forcing the daimyō of every han to move periodically between Edo and his han.^[8]

In recent years the Tosa Kaidō has been maintained through the efforts of volunteers. Hikers can walk on a footpath from Kawanoe to Otoyo, Kochi. (The path sometimes joins Ehime prefectural road 5.)

Shodo Girls

The 2010 movie Shodo Girls!! Watashi-tachi no Koshien was filmed in Shikokuchūō. The movie is about a high school calligraphy club which prepares to compete in the "Shodo Girls Koshien"—a performance calligraphy event involving teams drawing on 10m x 12m sheets of paper while performing to music. Shodo Girls is based on a true story.
