Katori Sea
The refers to the vanished inland sea formerly located in the eastern part of the ancient Kantō Plain connected to the Pacific Ocean, between the prefectures of Ibaraki and Chiba in Japan. Inland sea In the Jōmon period part of the Kantō Plain was covered by the sea, due to the Holocene glacial retreat, which peaked about 6,000 years ago. After thousands of years the land rose and the sea receded, and in the Yayoi period and the Kofun period much of the area was covered by wetlands, lakes and lagoons. Over the centuries the sea decreased in size, a further cause of which was the deposition of volcanic ash from the nearby mountains and around Kantō. The volcanic ash fell in great quantity, and was also carried by the wind, by the rain, spilled into the rivers, from where it reached the Katori Sea and the Pacific Ocean. Additionally the sediments and rocks that flowed in the rivers influenced the decrease in size of the Katori. Later the Lake Kasumigaura was formed fr ...

Jōmon Period
The is the time in Japanese history, traditionally dated between 6,000–300 BCE, during which Japan was inhabited by a diverse hunter-gatherer and early agriculturalist population united through a common Jōmon culture, which reached a considerable degree of sedentism and cultural complexity. The name "cord-marked" was first applied by the American zoologist and orientalist Edward S. Morse, who discovered sherds of pottery in 1877 and subsequently translated it into Japanese as ''Jōmon''.Mason, 14 The pottery style characteristic of the first phases of Jōmon culture was decorated by impressing cords into the surface of wet clay and is generally accepted to be among the oldest in the world. The Jōmon period was rich in tools and jewelry made from bone, stone, shell and antler; pottery figurines and vessels; and lacquerware.Imamura, K. (1996) ''Prehistoric Japan: New Perspectives on Insular East Asia''. Honolulu: University of Hawaii Press It is often compared to pr ...

Holocene Glacial Retreat
The Holocene glacial retreat is a geographical phenomenon that involved the global retreat of glaciers (deglaciation) that previously had advanced during the Last Glacial Maximum. Ice sheet retreat initiated ca. 19,000 years ago and accelerated after ca. 15,000 years ago. The Holocene, starting with abrupt warming 11,700 years ago, resulted in rapid melting of the remaining ice sheets of North America and Europe. Geographical alterations Antarctica Radiocarbon dating has been used to date the start of glacial retreat on Alexander island 18,000 years ago. The outermost locations like Marguerite Bay were fully deglaciated 12,000 years ago and the further inland locations continued deglaciating for an additional 3,000 years. The Larsen ice shelf was formed in the early Holocene at a latest estimation of 10,700 years ago. Certain segments of the ice shelf have collapsed as recently as 1995 for Larsen A and a large segment of Larsen B collapsed in 2002. Europe The many valleys ...

Edo Period
The or is the period between 1603 and 1867 in the history of Japan, when Japan was under the rule of the Tokugawa shogunate and the country's 300 regional '' daimyo''. Emerging from the chaos of the Sengoku period, the Edo period was characterized by economic growth, strict social order, isolationist foreign policies, a stable population, perpetual peace, and popular enjoyment of arts and culture. The period derives its name from Edo (now Tokyo), where on March 24, 1603, the shogunate was officially established by Tokugawa Ieyasu. The period came to an end with the Meiji Restoration and the Boshin War, which restored imperial rule to Japan. Consolidation of the shogunate The Edo period or Tokugawa period is the period between 1603 and 1867 in the history of Japan, when Japan was under the rule of the Tokugawa shogunate and the country's regional '' daimyo''.

Tokugawa Shogunate
The Tokugawa shogunate (, Japanese 徳川幕府 ''Tokugawa bakufu''), also known as the , was the military government of Japan during the Edo period from 1603 to 1868. Nussbaum, Louis-Frédéric. (2005)"''Tokugawa-jidai''"in ''Japan Encyclopedia'', p. 978.Nussbaum"''Edo-jidai''"at p. 167. The Tokugawa shogunate was established by Tokugawa Ieyasu after victory at the Battle of Sekigahara, ending the civil wars of the Sengoku period following the collapse of the Ashikaga shogunate. Ieyasu became the ''shōgun,'' and the Tokugawa clan governed Japan from Edo Castle in the eastern city of Edo (Tokyo) along with the ''daimyō'' lords of the ''samurai'' class.Nussbaum"Tokugawa"at p. 976. The Tokugawa shogunate organized Japanese society under the strict Tokugawa class system and banned most foreigners under the isolationist policies of '' Sakoku'' to promote political stability. The Tokugawa shoguns governed Japan in a feudal system, with each ''daimyō'' administering a '' han'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kofun Period
The is an era in the history of Japan from about 300 to 538 AD (the date of the introduction of Buddhism), following the Yayoi period. The Kofun and the subsequent Asuka periods are sometimes collectively called the Yamato period. This period is the earliest era of recorded history in Japan, but studies depend heavily on archaeology since the chronology of historical sources tends to be distorted. The word ''kofun'' is Japanese for the type of tumulus, burial mound dating from this era. It was a period of cultural import. Continuing from the Yayoi period, the Kofun period is characterized by influence from China and the Korean Peninsula; archaeologists consider it a shared culture across the southern Korean Peninsula, Kyūshū and Honshū. On the other hand, the most prosperous keyhole-shaped burial mounds in Japan during this period were approximately 5,000 in Japan from the middle of the 3rd century in the Yayoi period to the 7th century in the Asuka period, and many of them ha ...

Yayoi Period
The started at the beginning of the Neolithic in Japan, continued through the Bronze Age, and towards its end crossed into the Iron Age. Since the 1980s, scholars have argued that a period previously classified as a transition from the Jōmon period should be reclassified as Early Yayoi. The date of the beginning of this transition is controversial, with estimates ranging from the 10th to the 3rd centuries BC. The period is named after the neighbourhood of Tokyo where archaeologists first uncovered artifacts and features from that era in the late 19th century. Distinguishing characteristics of the Yayoi period include the appearance of new Yayoi pottery styles and the start of an intensive rice agriculture in paddy fields. A hierarchical social class structure dates from this period and has its origin in China. Techniques in metallurgy based on the use of bronze and iron were also introduced from China via Korea to Japan in this period. The Yayoi followed the Jōmon peri ...

Lake Kasumigaura
is the second-largest lake in Japan, located 60 km to the north-east of Tokyo. In a narrower sense and officially, Lake Kasumigaura refers to a waterbody with an area of 167.63 km2. In a wider sense, Lake Kasumigaura can also refer to a group of contiguous lakes, which includes Lake Kasumigaura proper, hereby referred to as Nishiura (西浦), and two smaller lakes, Kitaura (北浦; 35.16 km2) and Sotonasakaura (外浪逆浦; 5.85 km2), and also encompasses the rivers connecting them. In this case the total area is 220 km2. About 45% of the land surrounding the lake is natural landscape and 43.5% is agricultural land. History Lake Kasumigaura originally was a brackish-water lagoon, with indirect connections to the Pacific Ocean via the Hitachigawa and Tone Rivers. In 1963, the construction of a gate near the confluence of these rivers disconnected the lake from its sources of ocean water. As a result, the salinity of Lake Kasumigaura declined, and to ...
