Shimane Prefecture (島根県, Shimane-ken) is a prefecture of Japan located in the Chūgoku region of Honshu.^[1] Shimane Prefecture is the second-least populous prefecture of Japan at 665,205 (February 1, 2021) and has a geographic area of 6,708.26 km². Shimane Prefecture borders Yamaguchi Prefecture to the southwest, Hiroshima Prefecture to the south, and Tottori Prefecture to the east.

Matsue is the capital and largest city of Shimane Prefecture, with other major cities including Izumo, Hamada, and Masuda.^[2] Shimane Prefecture contains the majority of the Lake Shinji-Nakaumi metropolitan area centered on Matsue, and with a population of approximately 600,000 is Japan's second-largest metropolitan area on the Sea of Japan coast after Niigata. Shimane Prefecture is bounded by the Sea of Japan coastline on the north, where two-thirds of the population live, and the Chūgoku Mountains on the south. Shimane Prefecture governs the Oki Islands in the Sea of Japan which juridically includes the disputed Liancourt Rocks (竹島, Takeshima). Shimane Prefecture is home to Izumo-taisha, one of the oldest Shinto shrines in Japan, and the Tokugawa-era Matsue Castle.

History[]

Early history[]

The history of Shimane starts with Japanese mythology. The Shinto god Ōkuninushi was believed to live in Izumo, an old province in Shimane. Izumo Shrine, which is in the city of Izumo, honors the god.^[3]　At that time, the current Shimane prefecture was divided into three parts: Iwami, Izumo, and Oki.^[4] That lasted until the abolition of the han system took place in 1871. During the Nara period, Kakinomoto no Hitomaro read a poem on Shimane's nature when he was sent as the Royal governor.^[5]

Later on in the Kamakura period, Kamakura shogunate forced emperors Go-Toba and Godaigo into exile in Oki. Emperor Go-Daigo later escaped away from Oki and began rallying supporters against the shogunate, which succeeded.^[6]

Middle Ages[]

During the Muromachi period, Izumo and Oki were controlled by the Kyogoku clan. However, after the Ōnin War, the Amago clan expanded power based in Gassantoda Castle and the Masuda clan dominated Iwami Province. The Iwami Ginzan Silver Mine was located between Amago territory and Masuda territory, so there were many battles between these clans for the silver. However, in 1566 Mōri Motonari conquered Izumo, Iwami, and Oki.^[6] After over 30 years of Mori control, in 1600 Horio Yoshiharu entered Izumo and Oki as the result of Battle of Sekigahara, which Mori lost. Following the change, Horio Yoshiharu decided to move to build Matsue Castle instead of Gassan-Toda, and soon after Yoshiharu's death the castle was completed. Later in 1638, the grandson of Tokugawa Ieyasu, became the ruler because the Horio clan had no heir, and his family ruled until the abolition of the han system.

The Iwami area was split into three regions: the mining district, under the direct control of the Shogunate, the Hamada clan region, and the Tsuwano clan region. The Iwami Ginzan, now a UNESCO World Heritage Site produced silver and was one of the nation's largest silver mine by the early 17th century. The Hamada clan was on the shogunate's side in the Meiji Restoration, and the castle was burned down. The Tsuwano clan, despite then being ruled by the Matsudaira, was on the emperor's side in the restoration.^[7]

Modern Age[]

In 1871, the abolition of the han system placed the old Shimane and Hamada Provinces in the current area of Shimane Prefecture. Later that year, Oki became part of Tottori. In 1876, Hamada Prefecture was merged into the Shimane Prefecture. Also, Tottori Prefecture was added in the same year. However, five years later, in 1881, the current portion of Tottori Prefecture was separated and the current border was formed.^[7]

Geography[]

Shimane Prefecture is situated on the Sea of Japan side of the Chūgoku region. Because of its mountainous landscape, rice farming is done mostly in the Izumo plain where the city of Izumo is located.^[8] Another major landform is the Shimane peninsula. The peninsula is located across the Sea of Japan from Izumo to Sakaiminato, which is located in Tottori prefecture. Also, the peninsula created two brakish lakes, Lake Shinji and Nakaumi. The island of Daikon is located in Nakaumi. Off the main island of Honshū, the island of Oki belongs to Shimane prefecture as well. The island itself is in the Daisen-Oki National Park.^[8] Shimane also claims the use of Liancourt Rocks, over which they are in dispute with South Korea.^[9]

As of 1 April 2012, 6% of the total land area of the prefecture was designated as Natural Parks, namely Daisen-Oki National Park; Hiba-Dōgo-Taishaku and Nishi-Chūgoku Sanchi Quasi-National Parks; and eleven Prefectural Natural Parks.^[10]

Most major cities are located either on the seaside, or along a river.^[8]

Cities[]

Eight cities are located in Shimane Prefecture, the largest in population being Matsue, the capital, and the smallest being Gōtsu. The cities Masuda, Unnan, Yasugi, and Gōtsu had a slight population increase due to the mergers in the early 2000s.^[11]

Demographics[]

One-third of the prefecture's population is concentrated in the Izumo-Matsue area. Otherwise, over two-thirds of the population is on the coastline. The reason is that the Chūgoku Mountains make the land inland harder to inhabit. The capital, Matsue, has the smallest population out of all the 47 prefectural capitals. Shimane has also the largest percentage of the elderly.^[11] The province had an estimated 743 centenarians per million inhabitants in September 2010, the highest ratio in Japan, overtaking Okinawa Prefecture (667 centenarians per million).^[16]
