Saikaidō

Saikaidō (西海道, literally, "western sea circuit" or "western sea region") is a Japanese geographical term. It means both an ancient division of the country and the main road running through it. Saikaido was one of the main circuits of the Gokishichidō system, which was originally established during the Asuka Period.

This name identified the geographic region of Kyūshū and the islands of Tsushima and Iki. It consisted of nine ancient provinces and two islands. The provinces included Chikuzen, Chikugo, Buzen, Bungo, Hizen, Higo, Hyūga, Satsuma and Ōsumi.

Kyushu

Kyushu (九州, Kyūshū, lit. "Nine Provinces") (Japanese pronunciation: [kjɯᵝːꜜɕɯᵝː]) is the third largest island of Japan and most southwesterly of its four main islands. Its alternate ancient names include Kyūkoku (九国^?, "Nine States") , Chinzei (鎮西^?, "West of the Pacified Area") , and Tsukushi-no-shima (筑紫島^?, "Island of Tsukushi") . The historical regional name Saikaidō (西海道, lit. West Sea Circuit) referred to Kyushu and its surrounding islands.

In the 8th century Taihō Code reforms, Dazaifu was established as a special administrative term for the region.

As of 2006, Kyushu has a population of 13,231,995 and covers 35,640 square kilometres (13,760 sq mi).

Geography

The island is mountainous, and Japan's most active volcano, Mt Aso at 1,591 metres (5,220 ft), is on Kyushu. There are many other signs of tectonic activity, including numerous areas of hot springs. The most famous of these are in Beppu, on the east shore, and around Mt. Aso, in central Kyushu. The island is separated from Honshu by the Kanmon Straits.

Okinawa Prefecture

Okinawa Prefecture (Japanese: 沖縄県, Hepburn: Okinawa-ken, Okinawan: ウチナーチン Uchinaa-chin) is the southernmost prefecture of Japan. It comprises hundreds of the Ryukyu Islands in a chain over 1,000 kilometres (620 mi) long. The Ryukyus extend southwest from Kyushu (the southwesternmost of Japan's main four islands) to Taiwan. The Okinawa Prefecture encompasses the southern two thirds of that chain. Naha, Okinawa's capital, is located in the southern part of Okinawa Island.

History

The oldest evidence of human existence on the Ryukyu islands is from the Stone Age and was discovered in Naha and Yaese. Some human bone fragments from the Paleolithic era were unearthed, but there is no clear evidence of Paleolithic remains. Japanese Jōmon influences are dominant on the Okinawa Islands, although clay vessels on the Sakishima Islands have a commonality with those in Taiwan.

The first mention of the word Ryukyu was written in the Book of Sui. Okinawa was the Japanese word identifying the islands, first seen in the biography of Jianzhen, written in 779. Agricultural societies begun in the 8th century slowly developed until the 12th century. Since the islands are located at the eastern perimeter of the East China Sea relatively close to Japan, China and South-East Asia, the Ryukyu Kingdom became a prosperous trading nation. Also during this period, many Gusukus, similar to castles, were constructed. The Ryukyu Kingdom entered into the Imperial Chinese tributary system under the Ming dynasty beginning in the 15th century, which established economic relations between the two nations.
