The Kitamatsuura Peninsula ( 北松浦半島 , Kitamatsuura Hantō ) is a peninsula located in northwest Kyūshū , projecting northwest from an imaginary line drawn between Imari in Saga Prefecture and Sasebo in Nagasaki Prefecture , Japan . The peninsula is bounded by the Sea of Japan on the west, southwest and the north. Most of the peninsula is within the boundaries of the city of Hirado and Nagasaki Prefecture. The general area of and near the peninsula is commonly called the Hokushō Region ( 北松地方 , Hokushō Chihō ) .
20-486: Kitamatsuura Peninsula has many bays, inlets, and other coastal features along its shores. Imari Bay is located on the north, the Hirado Strait is located to the west between Hirado Island and the peninsula, and Sasebo Bay is found on the southwest. The peninsula is mainly basalt which forms a gently-sloping tableland and pediment , though it features many small hills and uneven terrain as well. The borders of
40-683: A fish market and handles the largest volume in Japan of Japanese jack mackerel and related fish . The area of the Kitamatsuura Peninsula includes part or all of several municipalities , including Imari in Saga Prefecture, as well as Sasebo (formerly Shikamachi and Kosaza ), Hirado (formerly Tabira), Matsuura, and Saza in Nagasaki Prefecture. The main rail transportation on the Kitamatsuura Peninsula
60-546: Is designated the Hokushō Prefectural Natural Park ( 北松県立自然公園 , Hokushō Kenritsu Shizen Kōen ) . Saikai National Park ( 西海国立公園 , Saikai Kokutei Kōen ) and Genkai Quasi-National Park ( 玄海国定公園 , Genkai Kokutei Kōen ) are located on the north side of the peninsula. Due to the rugged coastline, the fishing industry is very active on Kitamatsuura Peninsula. Tsukinokawa Port in Matsuura hosts
80-438: Is greatly moderated by the surrounding sea, resulting in reduced seasonal and diurnal temperature variations. Horst (geology) In physical geography and geology , a horst is a raised fault block bounded by normal faults . Horsts are typically found together with grabens . While a horst is lifted or remains stationary, the grabens on either side subside . This is often caused by extensional forces pulling apart
100-461: Is handled by the Nishi-Kyūshū Line , a rail line operated by Matsuura Railway . National Route 204 , which carries traffic between Karatsu in Saga Prefecture and Sasebo in Nagasaki Prefecture, and National Route 498 , carrying traffic between Kashima in Saga Prefecture and Imari. The Hirado Bridge ( 平戸大橋 , Hirado Ōhashi ) , part of National Route 383 , operates a bridge connecting
120-597: Is highly indented and feature a large cliffs along the entire north-west coast facing East China Sea , except for river mouths. The Hirado Island port was the primary departure point for the Japanese missions to Sui China and Japanese missions to Tang China in 7th-9th centuries. 16 October 1274, the Hirado Island was invaded by the detachment of the Mongol army as the part of Mongol invasions of Japan . During
140-476: The tsuyu ( 梅雨 , tsuyu , "plum rain") — the rainy season — occurring between early June (average:Jun.7) to late July (average:Jul.21). The island's weather is affected by the nearby Liman current [ ja ] while being shielded from the warm Kuroshio Current by the Kyushu island, resulting in wetter and colder climate than should be expected at lower 30's latitudes. The climate of Hirado Island
160-499: The Ikitsuki Island . The island is served by the national Route 383 . Ferries are available for transfer to the lesser inhabited islands nearby. Hirado Island is located in the humid subtropical climate zone ( Köppen Cfa ), with four distinct seasons. The island rarely sees snowfall during the winter. Spring in Hirado Island starts off mild, but ends up being very humid. The summer tends to be Hirado's wettest season, with
180-613: The Russian Plain , Arabia , India and Central South Africa . This is in distinction to folded regions such as some mountain chains of Eurasia . The Midcontinent Rift System in North America is marked by a series of horsts extending from Lake Superior to Kansas . The Rwenzori Mountains in the East African Rift are an upthrown fault block, and are the highest non-volcanic, non-orogenic mountains in
200-611: The Table , Jura , the Dole mountains and the Rila – Rhodope Massif including the well defined horsts of Belasitsa (linear horst), Rila mountain (vaulted domed shaped horst) and Pirin mountain – a horst forming a massive anticline situated between the complex graben valleys of Struma and that of Mesta . Larger areas where the continent remains stable with horizontal table-land stratification can be considered horsts, such as
220-699: The 2nd invasion of 1281, the island was an important rear base for the Mongols until being abandoned after the invasion failed. Since Muromachi period in 14th century, the island had become the hub for the Wokou pirates. In the development of the Nanban trade with Europe, the Portuguese trade station was operational on the island in 1550-1561 period. In 1584, the Spanish, British and Dutch traders started visiting

#1732772623692240-463: The closure of many of the mines in the area. The coastline of Kitamatsuura Peninsula is constantly changing due to erosion from the wind, rain, and ocean waves. The western area of the peninsula is a very wide and flat drowned river valley filled with many small islands including the Kujūku Islands . Much of the area is part of Saikai National Park . The coastal area between Tabira and Matsuura
260-639: The crust. Horsts may represent features such as plateaus, mountains, or ridges on either side of a valley. Horsts can range in size from small fault blocks up to large regions of stable continent that have not been folded or warped by tectonic forces. The word Horst in German means "mass" or "heap" and was first used in the geological sense in 1883 by Eduard Suess in The Face of the Earth. Horsts may have either symmetrical or asymmetrical cross-sections. If
280-518: The island once again. The Hirado Domain was established and Hirado Castle built under leadership of the Matsuura clan in 1599. The castle was razed in 1613 and re-built in 1704. In 1609–1641, a Dutch trading post was established on Hirado Island before being transferred to Dejima . From 1613, the ships of William Adams started operating from Hirado Island too, but the British trade mission
300-472: The island's total area. Hirado Island was formed as a horst elevated from the sea in Pliocene period. Its bedrock features a mixture of the sea sedimentary rocks of Tertiary period, mixed and overlaid by the recent igneous rock . Due to being relatively young, the island is very hilly with large fraction of area over 200 meters elevation, and flat land is limited to marginal coastal plains. The coastline
320-484: The normal faults to either side have similar geometry and are moving at the same rate, the horst is likely to be symmetrical and roughly flat on top. If the faults on either side have different rates of vertical motion, the top of the horst will most likely be inclined and the entire profile will be asymmetrical. Erosion also plays a significant role in how symmetrical a horst appears in cross-section. Horsts can form structural petroleum traps . In many rift basins around
340-581: The peninsula to Hirado Island. Hirado Island Hirado Island ( 平戸島 , Hiradoshima ) (also previously named Hiranoshima and Firando Island) is the 4th largest island in Nagasaki Prefecture , located in the Sea of Japan . The entire island and the part of the nearby Kyushu mainland is administered as part of Hirado city. The island's highest peak is Mount Yasumandake 535 m (1,755 ft). Saikai National Park comprise 24% of
360-578: The tableland are very steep. There is abundant evidence of ancient landslide activity throughout the peninsula. Much of the land is covered in rice fields , irrigated largely by abundant reservoirs . Within the stratum laid down during the Tertiary period , abundant coal deposits are found. These resources were developed following World War II , creating rapid economic growth in the Hokushō Region. However, alternative energy activism has led to
380-825: The world, the vast majority of discovered hydrocarbons are found in conventional traps associated with horsts. For example, much of the petroleum found in the Sirte Basin , Libya (of the order of tens of billions of barrels of reserves) are found on large horst blocks such as the Zelten Platform and the Dahra Platform and on smaller horsts such as the Gialo High . The Vosges Mountains in France and Black Forest in Germany are examples of horsts, as are
400-437: Was closed in 1623. In 2005, the city merged with the neighboring towns of Tabira , Ikitsuki , forming Hirado city , compromising all of Hirado Island as well as part of Kyushu. The Hirado Bridge traverses the over-570-meters-wide strait that connects the Hirado Island to Kyushu . The bridge was completed in 1977 and the transit fee was cancelled in 2010. Also, Ikitsuki Bridge (completed in 1991) connects Hirado Island to
