Mount Yōtei
is an active stratovolcano located in Shikotsu-Toya National Park, Hokkaidō, Japan. It is also called , "Ezo" being an old name for the island of Hokkaido, because it resembles Mount Fuji. The mountain is also known as . It is one of the 100 Famous Japanese Mountains, 100 famous mountains in Japan. Geology Mount Yōtei is mostly composed of andesite and dacite. The stratovolcano is symmetrical, adding to its resemblance to Mount Fuji. Eruptive history Tephrochronology indicates two eruptions at Mount Yotei. The most recent circa 1050 BC from a cone emerging from the northwest flank of the mountain at . The earlier eruption is dated from circa 3550 BC. Climate Avalanches On March 11, 2024, two backcountry skiers from New Zealand died after they were caught along with four others in an avalanche along the volcano's slopes. A third person from the group was injured. Etymology Mount Yōtei is also known as Ezo Fuji because of its almost perfectly conical shape resembling Moun ...

Meiji Era
The was an Japanese era name, era of History of Japan, Japanese history that extended from October 23, 1868, to July 30, 1912. The Meiji era was the first half of the Empire of Japan, when the Japanese people moved from being an isolated feudalism, feudal society at risk of colonization by Western world, Western powers to the new paradigm of a modern, industrialized nation state and emergent great power, influenced by Western scientific, technological, philosophical, political, legal, and aesthetic ideas. As a result of such wholesale adoption of radically different ideas, the changes to Japan were profound, and affected its social structure, internal politics, economy, military, and foreign relations. The period corresponded to the reign of Emperor Meiji. It was preceded by the Keiō era and was succeeded by the Taishō era, upon the accession of Emperor Taishō. The rapid modernization during the Meiji era was not without its opponents, as the rapid changes to society cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Hokkaido
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains t ...

Volcanoes Of Hokkaido
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is stretching a ...

Stratovolcanoes Of Japan
A stratovolcano, also known as a composite volcano, is a typically conical volcano built up by many alternating layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and explosive eruptions. Some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and solidifies before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high to intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less viscous mafic magma. Extensive felsic lava flows are uncommon, but can travel as far as 8 km (5 mi). The term ''composite volcano'' is used because strata are usually mixed and uneven instead of neat layers. They are among the most common types of volcanoes; more than 700 stratovolcanoes have erupted lava during the Holocene Epoch (the last 11,700 years), and many older, no ...

Active Volcanoes
An active volcano is a volcano that is currently erupting, or has the potential to erupt in the future. Conventionally it is applied to any that have erupted during the Holocene (the current geologic epoch that began approximately 11,700 years ago). A volcano that is not currently erupting but could erupt in the future is known as a dormant volcano. Volcanoes that will not erupt again are known as extinct volcanoes. Overview There are 1,350 potentially active volcanoes around the world, 500 of which have erupted in historical time. Many active volcanoes are located along the Pacific Rim, also known as the Pacific Ring of Fire. An estimated 500 million people live near active volcanoes. ''Historical time'' (or recorded history) is another timeframe for ''active''. The span of recorded history differs from region to region. In China and the Mediterranean, it reaches back nearly 3,000 years, but in the Pacific Northwest of the United States and Canada, it reaches back less tha ...

Ainu People
The Ainu are an Indigenous peoples, indigenous ethnic group who reside in northern Japan and southeastern Russia, including Hokkaido and the Tōhoku region of Honshu, as well as the land surrounding the Sea of Okhotsk, such as Sakhalin, the Kuril Islands, the Kamchatka Peninsula, and the Khabarovsk Krai. They have occupied these areas, known to them as "Ainu Mosir" (), since before the arrival of the modern Yamato people, Yamato and Treaty of Aigun, Russians. These regions are often referred to as and its inhabitants as in historical Japanese texts. Along with the Yamato and Ryukyuan people, Ryukyu ethnic groups, the Ainu people are one of the primary historic ethnic groups of Japan. Official surveys of the known Ainu population in Hokkaido received 11,450 responses in 2023, and the Ainu population in Russia was estimated at 300 in 2021. Unofficial estimates in 2002 placed the total population in Japan at 200,000 or higher, as the near-total Cultural assimilation, assimilatio ...

Rumex
The docks and sorrels, genus ''Rumex'', are a genus of about 200 species of annual, biennial, and perennial herbs in the buckwheat family, Polygonaceae. Members of this genus are very common perennial herbs with a native almost worldwide distribution, and introduced species growing in the few places where the genus is not native. Some are nuisance weeds (and are sometimes called dockweed or dock weed), but some are grown for their edible leaves. ''Rumex'' species are used as food plants by the larvae of a number of Lepidoptera species, and are the only host plants of '' Lycaena dispar'' and '' Lycaena rubidus.'' Description They are erect plants, usually with long taproots. The fleshy to leathery leaves form a basal rosette at the root. The basal leaves may be different from those near the inflorescence. They may or may not have stipules. Minor leaf veins occur. The leaf blade margins are entire or crenate. The usually inconspicuous flowers are carried above the leaves in clus ...

Empress Kōgyoku
, also known as , was the 35th and 37th monarch of Japan,Kunaichō 斉明天皇 (37)/ref> according to the traditional order of succession. Both her reigns were within the Asuka period. Kōgyoku's reign spanned the years from 642 to 645. Her reign as Saimei encompassed 655 to 661. In other words, * 642: She ascended the throne as Kōgyoku''-tennō'', and she stepped down in response to the assassination of Soga no Iruka (see: Isshi incident). * 645: She abdicated in favor of her brother, who would become known as Emperor Kōtoku. * 654: Kōtoku died and the throne was vacant. * 655: She re-ascended, beginning a new reign as Saimei''-tennō''. * 661: Saimei ruled until her death caused the throne to be vacant again. The two reigns of this one woman spanned the years from 642 through 661. In the history of Japan, Kōgyoku/Saimei was the second of eight women to take on the role of empress regnant. The sole female monarch before Kōgyoku/Saimei was Suiko''-tennō''. The six f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abe No Hirafu
was a Japanese military commander, strategist, and politician of the Asuka period. Some sources say he lived from c.575-664 Biography Events in his life are accounted in the Nihon Shoki and Kojiki, both written several decades after his death. His father's name and origin are unknown, as the written sources contradict one another, and may have been altered to glorify the genealogy of then-living clans. After reaching adulthood, Abe was a governor of Koshi Province. In 658, he defeated the Mishihase in "Watarishima" (which may mean Tsugaru Peninsula or Hokkaido) at the request of the native inhabitants. His men continued to raid and plunder in Hokkaido and Okushiri Island until 660, bringing numerous trophies and prisoners to court. His trophies included at least 2 live bears, 70 bear hides, and 353 prisoners. In March 660, local allies asked for his military assistance at Ishikari River in Hokkaido, where he was victorious again. In 662 his lord (soon to become the Emp ...

Nihon Shoki
The or , sometimes translated as ''The Chronicles of Japan'', is the second-oldest book of classical Japanese history. It is more elaborate and detailed than the , the oldest, and has proven to be an important tool for historians and archaeologists as it includes the most complete extant historical record of ancient Japan. The was finished in 720 under the editorial supervision of Prince Toneri with the assistance of Ō no Yasumaro and presented to Empress Genshō. The book is also a reflection of Chinese influence on Japanese civilization. In Japan, the Sinicized court wanted written history that could be compared with the annals of the Chinese. The begins with the Japanese creation myth, explaining the origin of the world and the first seven generations of divine beings (starting with Kuninotokotachi), and goes on with a number of myths as does the , but continues its account through to events of the 8th century. It is believed to record accurately the latter reig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
