Shugodai
were officials during feudal Japan. Shugodai were representatives of provincial shugo when the shugo could not virtually exercise his power, being often away from his province. Unlike shugo, who were appointed from the central power of the samurai estate or Shogunate, shugodai were locally appointed. At the brink of the Sengoku period, most shugo strengthened their grip on power, leading to the effective disappearance of their shugodai. However, taking advantage of the weakening of their Shugo due to war or other circumstances, some shugodai became the effective lords of their provinces. A typical example of shugodai becoming ''de facto'' ''daimyōs'' would be Oda Nobuhide, the Oda clan of Owari Province.

Shugo
, commonly translated as ' ilitarygovernor', 'protector', or 'constable', was a title given to certain officials in feudal Japan. They were each appointed by the shogun to oversee one or more of the provinces of Japan. The position gave way to the emergence of the daimyo (military feudal lords) in the late 15th century, as ''shugo'' began to claim power over lands themselves, rather than serving simply as governors on behalf of the shogunate. History The post is said to have been created in 1185 by shogun Minamoto no Yoritomo to aid the capture of Yoshitsune, with the additional motivation of extending the rule of the Minamoto shogunate government throughout Japan. The ''shugo'' (military governors) progressively supplanted the existing ''kokushi'' (civil governors), who were appointed by the Imperial Court in Kyoto. Officially, the ''gokenin'' in each province were supposed to serve the ''shugo'', but in practice, the relationship between them was fragile, as the gokenin were ...

Provinces Of Japan
were first-level administrative divisions of Japan from the 600s to 1868. Provinces were established in Japan in the late 7th century under the Ritsuryō law system that formed the first central government. Each province was divided into and grouped into one of the geographic regions or circuits known as the ''Gokishichidō'' (Five Home Provinces and Seven Circuits). Provincial borders often changed until the end of the Nara period (710 to 794), but remained unchanged from the Heian period (794 to 1185) until the Edo period (1603 to 1868). The provinces coexisted with the '' han'' (domain) system, the personal estates of feudal lords and warriors, and became secondary to the domains in the late Muromachi period (1336 to 1573). The Provinces of Japan were replaced with the current prefecture system in the ''Fuhanken sanchisei'' during the Meiji Restoration from 1868 to 1871, except for Hokkaido, which was divided into provinces from 1869 to 1882.

Mishihase
The , also read as Ashihase and Shukushin, were a people of ancient Japan, believed to have lived along the northern portion of the coast of the Sea of Japan. The term Sushen, rendered 肅愼, is found in Chinese records, but is annotated as Mishihase or Ashihase in Japanese language documents, which should have developed into *''Mishiwase'' or *''Ashiwase'' in modern Japanese if the word had survived in colloquial speech. According to the ''Nihon Shoki'', the Mishihase first arrived at Sado Island during the reign of Emperor Kinmei. In 660, Japanese General Abe no Hirafu defeated the Mishihase in ''"Watarishima"'' at the request of the native inhabitants. During the Edo period, Arai Hakuseki proposed that Watarishima was Ezo, which was later renamed Hokkaidō. The battle place was recorded as the mouth of a large river, which is proposed to be Ishikari River. Some historians consider that the Mishihase were identical to the Tungusic Sushen in Chinese records, but others think ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Population Density
Population density (in agriculture: Standing stock (other), standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans, but sometimes to other living organisms too. It is a key geographical term.Matt RosenberPopulation Density Geography.about.com. March 2, 2011. Retrieved on December 10, 2011. Biological population densities Population density is population divided by total land area, sometimes including seas and oceans, as appropriate. Low densities may cause an extinction vortex and further reduce fertility. This is called the Allee effect after the scientist who identified it. Examples of the causes of reduced fertility in low population densities are: * Increased problems with locating sexual mates * Increased inbreeding Human densities Population density is the number of people per unit of area, usually transcribed as "per square kilometre" or square mile, and which may include or exclude, for example, ar ...
