is a small peninsula town located in Nishiuwa District, Ehime Prefecture, Japan. , the town had an estimated population of 8,497 in 15638 households and a population density of 90 persons per km2. The total area of the town is

Following a recent merger with the neighboring towns of Misaki and Seto, the town now spans the mountainous Sadamisaki Peninsula, the narrowest peninsula in Japan and the westernmost point on the island of Shikoku.

This geography has influenced Ikata's growth. On the one hand, it has presented challenges to urban development that were not overcome until recently in the town's long history. On the other, the peninsula is what gives the town its mountain and ocean scenery which, bolstered by significant investments in infrastructure and tourist facilities, has formed the basis for a burgeoning tourism industry.

In addition to the beauty of its rugged, natural landscape, Ikata has long been known for fishing and mikan orange farming. In recent years Ikata has also become a hotspot of modern energy production—the Ikata Nuclear Power Plant produced much of Shikoku's electricity until it was shut down in 2012 following the 2011 Tōhoku earthquake and tsunami (before being reactivated in 2018), and the town's windy mountains are dotted by dozens of windmills.

Geography

Ikata is on the Sadamisaki Peninsula, Japan's narrowest peninsula and the westernmost point on the island of Shikoku. The peninsula is extremely mountainous, with steep cliffs and precious little usable flat land. To combat this, the town's bays and ponds have seen vigorous coastal reclamation efforts dating back to the early Meiji period (late 1800s). Ikata's mountainsides are covered with terraced mikan fields, and natural forest in the undeveloped areas.

The various neighborhoods of Ikata are found nestled among the foothills of the mountains, connected only by winding coastal roads and a single highway, Route 197. The biggest of the neighborhoods and the administrative center of Ikata is Minatoura, near the eastern edge of the town.

Ikata is surrounded on three sides by ocean—the Iyo Sea (part of the Inland Sea) to the north, the Uwa Sea (Pacific Ocean) to the south, and the Hōyo Strait (separating Shikoku from Kyūshū) to the west.

Climate The climate in Ikata is warm, with an average year-round temperature of and more than of yearly rain. The coldest parts of winter remain above freezing ( on average), with snowfall seen only once or twice per year. Rain is concentrated in the rainy season in June and July, and also in September.

The length of the peninsula makes accurate weather prediction difficult for the town; when driving down Melody Line, it is not uncommon to find it sunny between one set of tunnels, rainy between another, and foggy between yet another. Ikata's position, stretching out into the ocean, also makes it a frequent target for typhoons.

Demographics

Ikata is a small town, with a population of 8,196 as of June 30, 2023. The total land area of the town is 94.37 km2, making the population density 113 persons per km2. However, much of the land on the peninsula is quite mountainous and not suited for development; the population density of the individual settlements, which are squeezed into the small bay areas in the foothills of the mountains, is much higher. Extrapolating from data based on the most recent land survey, 国土交通省地籍調査 伊方町 only 3.21% of the town's land is inhabited; this puts the population density at a much higher 3,510 persons/kilometer-squared.

Like much of rural Japan, Ikata faces a rapidly declining and aging population. According to the Ikata website, roughly 40% of the town's population is 65 or older.Town of Ikata: Statistics. Furthermore, many elementary and middle schools have closed since the 1970s. Those that remain have very small student populations. For example, Ikata Elementary School is Ikata's largest elementary school; there were 303 students in 1987, 162 in 2006, and 128 in 2014; Toyonoura Elementary was Old Ikata's smallest school; it had 51 students in 1987, and only 14 in 2007. before it closed in 2010. Currently, Futami Elementary is Ikata's smallest Elementary school with 21 students. However, plans are in effect to close the school at the end of the current fiscal year (April, 2015).

This population issue was a significant part of the impetus for the recent merger of Old Ikata with Seto and Misaki. While Old Ikata is geographically more accessible, and has enjoyed the economic benefits of the Ikata Nuclear Power Plant, Seto and Misaki have experienced even more severe aging and decline of their populations. In 2000, Seto's working-age population dipped below 50% of its total.

Ethnically Ikata is extremely homogeneous with only a handful of non-Japanese residents, most of whom are either temporary farm laborers from China, or English educators on the JET Programme.

Per Japanese census data,Ikata population statistics the population of Ikata has been decreasing steadily since the 1950s, and is now less than third of what it was a century ago.

History

Prehistory The Sadamisaki Peninsula area has been inhabited since at least the Jōmon period (10,000–300 BC), as evidenced by the discovery of stone tools and earthenware pots in the Misaki and Kushi neighborhoods.

In 1963 a local man discovered a stone ax dating to the mid-Yayoi period (300 BC–250 AD) in his farm plot in the Kawachi neighborhood. Upon further investigation by the Japan Archaeological Society in 1986, the area was recognized as containing the remains of a . This is a type of settlement usually located several tens of meters above the surrounding area on mountainsides, and is peculiar to the Yayoi period.

Classical era After the Taika Reform of 646, Ikata and the greater surrounding area became known as the Uwa District in 701. The Uwa District covered the entire Nanyo region (map) until it was split in two in 866. Since districts were defined by population, one can infer that the area was underdeveloped and sparsely populated at the time.

Feudal era

Towards the end of the Heian period, the Yawatahama and Ikata area became known as . As ownership of farmlands became increasingly concentrated in the hands of local ruling families, control of the Yano area was given to Taira no Tadamitsu, a member of the Heike clan.

Some members of the Heike family secretly settled in the Seto area in 1185 after being defeated in the Genpei Wars. Ikata-Seto-Misaki Merger Conference No. 9 Reference Material, September 29, 2005 (PDF).

Entering the Edo period and the Tokugawa shogunate, the Uwa District came under control of the . From 1610 to 1612, the first Uwajima feudal lord, Tomita Nobutaka, gathered farmers from the local area to dig a canal through the thinnest part of the Sadamisaki Peninsula, Seto's Mitsukue neighborhood. The project was soon canceled due to insufficient funds. By this time, the name can be seen in records of taxes paid to the feudal lords. The Mitsukue neighborhood prospered as a port town during the feudal period, as it was used as a port of rest for daimyō on their way to and from the capital as part of the sankin-kōtai system. This traffic was likely the source of the demand for Nobutaka's abortive attempt to create a shortcut through the peninsula.

Modern era

A decade after the Meiji Restoration, in March 1878 the Uwa District was divided into the current Kitauwa, Minamiuwa, Higashiuwa, and Nishiuwa districts (North-, South-, East-, and West-Uwa, respectively). Ikata was designated a in 1889 with the establishment of the modern municipalities system, and other neighborhoods along the peninsula soon followed suit, many merging to reduce the number of independent settlements from 26 to 6.

More recently, Seto's Mitsukue Bay was used for submarine training operations by the Imperial Japanese Navy leading up to World War II, as the bay's shape is similar to that of Pearl Harbor. Hotta Construction Corp. "Memories of Past Construction Projects" No. 10 (March 2007). A monument named stands in Suka Park in Mitsukue as a memorial dedicated to the nine young men (ages 21–28) who were stationed in the Mitsukue area for these exercises. According to the plaque on the monument, the men were quite friendly with the locals, and stories are still told about them in the neighborhood to this day. The men died on December 8, 1941, during one of the initial attacks on Pearl Harbor.

In 1955 another round of mergers corresponding to the Great Shōwa Merger reduced the number of municipal entities to three.

In 1977 the Ikata Nuclear Power Plant began operation as the first nuclear power plant on the island of Shikoku.

On April 1, 2005, Ikata merged with the nearby towns of Misaki and Seto to create the new town of Ikata, which spans the Sadamisaki Peninsula.

The installation of many new windmills in 2006 and 2007 solicited a significant amount of noise complaints from nearby residents."Around Japan / Ikata, Ehime Prefecture: Noisy wind turbines stir up protests", Asahi Shimbun, May 15, 2007. Reproduced at Wind-Watch.org.

In March 2014, national attention turned to Ikata as the towns elections near. Many wondered if Ikata would approve the restart of its nuclear power generators.New York Times: Warily Leading Japan's Nuclear Awakening

Government and politics Ikata has a mayor-council form of government with a directly elected mayor and a unicameral city council of 13 members. Ikata together with Yawatahama, contributes two members to the Ehime Prefectural Assembly. In terms of national politics, Ikata is part of Ehime 3rd district of the lower house of the Diet of Japan. Prior to 2022, the town was part of Ehime 4th district.

Ikata experienced significant political turbulence leading up to and immediately following the April 1, 2005 merger with Seto and Misaki. To begin with, multiple potential merger plans were put forth, one of which was for all of the contiguous Nishiuwa District towns (Misaki, Seto, Old Ikata, and Honai) to merge. However, when Honai announced that it would merge with the nearby city of Yawatahama, polls indicated that Misaki residents still preferred to merge with Honai and Yawatahama, rather than Seto and Old Ikata, despite their being discontiguous (a Misaki-Honai-Yawatahama merger would make Misaki an exclave). Ultimately this was found to be impractical, and the Misaki-Seto-Ikata merger was approved with some grumbling over the naming of the new town. Once the merger was decided upon, suggestions for the new town's name were solicited from the residents. Despite the many other reasonable suggestions Naming suggestions for the new town of Ikata. and the seeming unfairness toward Seto and Misaki, the "new" name was chosen to be "Ikata."
