Rishiri Island
is a volcanic island in the Sea of Japan off the coast of Hokkaido, Japan. Administratively the island is part of Hokkaido Prefecture, and is divided between two towns, Rishiri and Rishirifuji. The island is formed by the cone-shaped extinct volcanic peak of Mount Rishiri. Along with Rebun Island and the coastal area of the Sarobetsu Plain, Rishiri forms the Rishiri-Rebun-Sarobetsu National Park. The main industries of Rishiri are tourism and fishing. The island has a population of 5,102 residents. Etymology Rishiri derives its name from the Ainu language, and means "high island", or "island with a high peak", a reference to the altitude of Mount Rishiri above sea level. Geography Rishiri Island is located roughly west of Hokkaido; Rebun Island is a further to the northwest. Rishiri is roughly circular with a coastline of . The island spans from north to south and from east to west. Mount Rishiri rises to an altitude of and provides a good source of fresh water; ...

Mount Rishiri
is a Quaternary stratovolcano located off the coast of Hokkaidō, Japan in the Sea of Japan. It rises out of the Sea of Japan forming Rishiri Island. Because its cone shape resembles Mount Fuji it is sometimes referred to as Rishiri Fuji. It is one of the 100 famous mountains in Japan. Mount Rishiri's opening festival is held annually on July 2 and July 3. This festival officially opens the climbing season. Geology Mount Rishiri is made up of alkali and non-alkali mafic volcanic rock dating from the Late Pleistocene, 130,000–18,000 years ago. Otherwise it is covered in Quaternary volcanic rock debris. Climbing route The ascent of Rishiri is challenging in places and not suitable for novice hikers. There is a campsite partway up the mountain from the dock, and an unmanned hut located a short distance below the summit. There is also a small shrine at the summit. On clear days the view extends to Hokkaidō, the adjacent island of Rebun, and as far as Sakhalin Island in Rus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Cone
Volcanic cones are among the simplest volcanic landforms. They are built by ejecta from a volcanic vent, piling up around the vent in the shape of a cone with a central crater. Volcanic cones are of different types, depending upon the nature and size of the fragments ejected during the eruption. Types of volcanic cones include stratocones, spatter cones, tuff cones, and cinder cones. Stratocone Stratocones are large cone-shaped volcanoes made up of lava flows, explosively erupted pyroclastic rocks, and igneous intrusives that are typically centered around a cylindrical vent. Unlike shield volcanoes, they are characterized by a steep profile and periodic, often alternating, explosive eruptions and effusive eruptions. Some have collapsed craters called calderas. The central core of a stratocone is commonly dominated by a central core of intrusive rocks that range from around to over several kilometers in diameter. This central core is surrounded by multiple generations of lav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Robin
The Japanese robin (''Larvivora akahige'') is a small passerine bird in the family Muscicapidae. This species was formerly named ''Erithacus akahige'', or ''Komadori''. Its range extends from the south of the Kuril and Sakhalin Islands throughout Japan. The name "Japanese robin" is also sometimes used for the red-billed leiothrix (''Leiothrix lutea''). The specific name ''akahige'' is, somewhat confusingly, the common name of its relative '' Larvivora komadori'' in Japanese. The Japanese robin, together with the Ryukyu robin and the European robin, was previously placed in the genus '' Erithacus'' . A 2006 molecular phylogenetic study found that the two east Asian species were more similar to the Siberian blue robin, at the time in '' Luscinia'', than to the European robin. In 2010 a large study confirmed this result and also found that ''Luscinia'' was non-monophyletic. The genus ''Larvivora'' was therefore resurrected to accommodate a clade containing the Japanese robin, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-tailed Gull
The black-tailed gull (''Larus crassirostris'') is a gull native to shorelines of East Asia. Description The black-tailed gull is medium-sized (46 cm) (19 Inches), with a wingspan of 126–128 cm (49.6 - 50.3 Inches). It has yellow legs and a red and black spot at the end of the bill. Males and females have identical plumage and features, although males are larger in size than females. This gull takes four years to reach full adult plumage. As the name suggests, it has a black tail. The bird has a cat-like call, giving it its Japanese name — ''umineko'' (海猫, "sea cat"), and Korean name — ''gwaeng-yi'' gull, which means "cat" gull. In Hachinohe their calls are one of the 100 Soundscapes of Japan. Distribution and habitat The species is resident to coastlines of the East China Sea, Japan, Manchuria and the Kuril Islands. It is a vagrant to Alaska and North America and has been found in the Philippines. In Japan The bird is common in Japan, nesting from Hokkaido ...

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking. History In 1985, following a specific request from the European Economic Community, Birdlife International dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Von Karman Vortices Off Rishiri Island, Japan
The term () is used in German surnames either as a nobiliary particle indicating a noble patrilineality, or as a simple preposition used by commoners that means or . Nobility directories like the often abbreviate the noble term to ''v.'' In medieval or early modern names, the particle was at times added to commoners' names; thus, meant . This meaning is preserved in Swiss toponymic surnames and in the Dutch , which is a cognate of but also does not necessarily indicate nobility. Usage Germany and Austria The abolition of the monarchies in Germany and Austria in 1919 meant that neither state has a privileged nobility, and both have exclusively republican governments. In Germany, this means that legally ''von'' simply became an ordinary part of the surnames of the people who used it. There are no longer any legal privileges or constraints associated with this naming convention. According to German alphabetical sorting, people with ''von'' in their surnames – of nobl ...

Fresh Water
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salt (chemistry), salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include non-salty mineral water, mineral-rich waters, such as chalybeate springs. Fresh water may encompass frozen water, frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ice pellets, sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranea (geography), subterranean subterranean river, rivers and underground lake, lakes. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to sur ...

Ainu Language
Ainu (, ), or more precisely Hokkaido Ainu (), is a language spoken by a few elderly members of the Ainu people on the northern Japanese island of Hokkaido. It is a member of the Ainu language family, itself considered a language family isolate with no academic consensus of origin. It is classified as Critically Endangered by the UNESCO ''Atlas of the World's Languages in Danger''. Until the 20th century, the Ainu languages – Hokkaido Ainu and the now-extinct Kuril Ainu and Sakhalin Ainu – were spoken throughout Hokkaido, the southern half of the island of Sakhalin and by small numbers of people in the Kuril Islands. Due to the colonization policy employed by the Japanese government, the number of Hokkaido Ainu speakers decreased through the 20th century, and it is now moribund. A very low number of elderly people still speak the language fluently, though attempts are being made to revive it. Speakers The term "Ainu" comes from the endonym of the Ainu people, ' (), ...
