Iwaizumi Station
was a railway station on the Iwaizumi Line in Iwaizumi, Iwate, Japan, operated by East Japan Railway Company (JR East). Lines Iwaizumi Station was the terminus of the Iwaizumi Line, and was located 38.4 rail kilometers from the starting point of the line at Moichi Station. Station layout The station had a single side platform serving traffic in both directions, connected to a two-story station building. The platform was designed as an island platform as there were plans to connect the station to the Kita Rias Line, but no track was laid on one side of the platform. History Iwaizumi Station opened on 6 February 1972. The station was absorbed into the JR East network upon the privatization of the Japanese National Railways (JNR) on 1 April 1987. Operations on the Iwaizumi Line were suspended from July 2010, due to a landslide, and the line was officially closed on 1 April 2014, owing to declining passenger use. Passenger statistics In fiscal 2010, the station was used by an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Solutional Cave
A solutional cave, solution cave, or karst cave is a cave usually formed in the soluble rock limestone. It is the most frequently occurring type of cave. It can also form in other rocks, including chalk, dolomite, marble, salt beds, and gypsum. Process Bedrock is dissolved by natural acid in groundwater that seeps through bedding-planes, faults, joints and so on. Over geological epochs these openings expand as the walls are dissolved to become caves or cave systems. The portions of a solutional cave that are below the water table or the local level of the groundwater will be flooded. Limestone caves The largest and most abundant solutional caves are located in limestone. Limestone caves are often adorned with calcium carbonate formations produced through slow precipitation. These include flowstones, stalactites, stalagmites, helictites, soda straws, calcite rafts and columns. These secondary mineral deposits in caves are called ''speleothems''. Carbonic acid dissol ...

Tōhoku Region
The , Northeast region, or consists of the northeastern portion of Honshu, the largest island of Japan. This traditional region consists of six prefectures (''ken''): Akita, Aomori, Fukushima, Iwate, Miyagi, and Yamagata. Tōhoku retains a reputation as a remote, scenic region with a harsh climate. In the 20th century, tourism became a major industry in the Tōhoku region. History Ancient & Classical period In mythological times, the area was known as Azuma (吾妻, あづま) and corresponded to the area of Honshu occupied by the native Emishi and Ainu. The area was historically the Dewa and the Michinoku regions, a term first recorded in (654). There is some variation in modern usage of the term "Michinoku". Tōhoku's initial historical settlement occurred between the seventh and ninth centuries, well after Japanese civilization and culture had become firmly established in central and southwestern Japan. The last stronghold of the indigenous Emishi on Honshu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Monument
A natural monument is a natural or natural/cultural feature of outstanding or unique value because of its inherent rarity, representative of aesthetic qualities or cultural significance. Under World Commission on Protected Areas guidelines, natural monuments are level III, described as: :"Areas are set aside to protect a specific natural monument, which can be a landform, sea mount, submarine cavern, geological feature such as a cave or even a living feature such as an ancient grove. They are generally quite small protected areas and often have high visitor value." This is a lower level of protection than level II (national parks) and level I (wilderness areas). The European Environment Agency's guidelines for selection of a natural monument are: * The area should contain one or more features of outstanding significance. Appropriate natural features include waterfalls, caves, craters, fossil beds, sand dunes and marine features, along with unique or representative fauna and flor ...

Flowstone
Flowstones are sheetlike deposits of calcite or other carbonate minerals, formed where water flows down the walls or along the floors of a cave. They are typically found in "solution caves", in limestone, where they are the most common speleothem. However, they may form in any type of cave where water enters that has picked up dissolved minerals. Flowstones are formed via the degassing of vadose percolation waters. Flowstone may also form on manmade structures as a result of calcium hydroxide being leached from concrete, lime or mortar. These secondary deposits created outside the cave environment, which mimic the shapes and forms of speleothems, are classified as " calthemites" and are associated with concrete degradation.Smith, G.K., (2016). “Calcite Straw Stalactites Growing From Concrete Structures”, Cave and Karst Science, Vol.43, No.1, P.4-10, (April 2016), British Cave Research Association, ISSN 1356-191X.

Subterranean Lake
An underground lake or subterranean lake is a lake underneath the surface of the Earth. Most naturally occurring underground lakes are found in areas of Karst topography, where limestone or other soluble rock has been weathered away, leaving a cave where water can flow and accumulate. Natural underground lakes are an uncommon hydrogeological feature. More often, groundwater gathers in formations such as aquifers or springs. The largest subterranean lake in the world is in Dragon's Breath Cave in Namibia, with an area of almost ; the second largest is The Lost Sea, located inside Craighead Caverns in Tennessee, United States, with an area of Characteristics In general terms, an underground lake is any body of water that is similar in size to a surface lake and exists mostly or entirely underground; though, a precise scientific definition of what may be considered a lake is not yet well-established. Underground lakes could be classified as either “lakes” or "ponds", ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caves Of Japan
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganism ...

Landforms Of Iwate Prefecture
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.

Tourist Attractions In Iwate Prefecture
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be domestic (within the traveller's own country) or international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Tourism numbers declined as a result of a strong economic slowdown (the late-2000s recession) between the second half of 2008 and the end of 2009, and in consequence of the outbreak of the 2009 H1N1 influenza virus, but slowly recovered until the COVID-19 p ...
