Sekka Zusetsu
''Sekka Zusetsu'' () is a figure collection written by Doi Toshitsura, the fourth ''daimyō'' of Koga Domain in 1832. Overview Koga Domain was located at the center of the Kantō Plain. Due to heavy snowfall, the Koga Domain was a good place to observe snowflakes. Doi Toshitsura, the fourth ''daimyō'' of Koga Domain started observing snowflakes as his hobby with his own microscope which was imported from the Netherlands, and he drew pictures and studies about snowflakes in the book. This figure collection of his is highly valued today in Japan as the first Japanese figure collection of snowflakes. It's said that Toshitsura had many difficulties observing snowflake properly because snowflakes need −10 to −15 Celsius degrees temperature to hold their correct shapes. So Toshitsura had to observe them under very cold temperatures. This book was written for him and his family (the Doi clan, ), but it had great influence on Japanese textile-patterns also.

Daimyō
were powerful Japanese magnates, feudal lords who, from the 10th century to the early Meiji era, Meiji period in the middle 19th century, ruled most of Japan from their vast, hereditary land holdings. They were subordinate to the shogun and nominally to the Emperor of Japan, emperor and the ''kuge''. In the term, means 'large', and stands for , meaning 'private land'. From the ''shugo'' of the Muromachi period through the Sengoku period, Sengoku to the ''daimyo'' of the Edo period, the rank had a long and varied history. The backgrounds of ''daimyo'' also varied considerably; while some ''daimyo'' clans, notably the Mōri clan, Mōri, Shimazu clan, Shimazu and Hosokawa clan, Hosokawa, were cadet branches of the Imperial family or were descended from the ''kuge'', other ''daimyo'' were promoted from the ranks of the samurai, notably during the Edo period. ''Daimyo'' often hired samurai to guard their land, and they paid the samurai in land or food as relatively few could aff ...

Koga Domain
file:Koga castle kannonjikuruwa dorui.jpg, alt=, Site of Koga Castle, administrative headquarters of Koga Domain was a Han (Japan), feudal domain under the Tokugawa shogunate of Edo period Japan. It is located in Shimōsa Province, Honshū. The domain was centered at Koga Castle, located in what is the city of Koga, Ibaraki, Koga in Ibaraki Prefecture. History During the Muromachi period, Koga was the seat of the Kantō kubō, under the Ashikaga clan, who vied with the Uesugi clan and with the Later Hōjō clan for control of eastern Japan. Ashikaga Ujinohime was the last Koga-kubo and owner of Koga domain of the Ashikaga lineage. When Toyotomi Hideyoshi defeated the Hōjō at the Siege of Odawara (1590), Siege of Odawara, the area fell into his hands, and was subsequently assigned (along with the rest of the Kantō region) to Tokugawa Ieyasu. Ieyasu assigned Koga Castle to his grandson-in-law, Ogasawara Hidemasa as ''daimyō'' of Koga Domain, with assessed ''kokudaka'' of 30,000 ...

Kantō Plain
The is the largest plain in Japan, and is located in the Kantō region of central Honshū. The total area of 17,000 km2 covers more than half of the region extending over Tokyo, Saitama Prefecture, Kanagawa Prefecture, Chiba Prefecture, Gunma Prefecture, Tochigi Prefecture and Ibaraki Prefecture. Geography The northern limit borders on the Abukuma Highlands, Yamizo Mountain Range, Ashio Mountain Range, and a volcanic field associated with the Nasu Volcanic Belt. The western coincides with the Kantō Mountain Range and the southern edge is defined by the Bōsō Peninsula, the Miura Hills, Tokyo Bay, and Sagami Bay. The Kashima Sea and Kujūkuri Beach define the eastern end of the plain. Most of the rivers originate in the northern or western mountain ranges and flow east or southeast into the Pacific Ocean, Tokyo Bay, or Sagami Bay. In the central part of the plain is the Tone River; in the northern part the Watarase River, Kinu River, Kokai River, Naka River, and Kuj ...

Snowflakes
A snowflake is a single ice crystal that has achieved a sufficient size, and may have amalgamated with others, which falls through the Earth's atmosphere as snow.Knight, C.; Knight, N. (1973). Snow crystals. Scientific American, vol. 228, no. 1, pp. 100–107.Hobbs, P.V. 1974. Ice Physics. Oxford: Clarendon Press. Each flake nucleates around a dust particle in supersaturated air masses by attracting supercooled cloud water droplets, which freeze and accrete in crystal form. Complex shapes emerge as the flake moves through differing temperature and humidity zones in the atmosphere, such that individual snowflakes differ in detail from one another, but may be categorized in eight broad classifications and at least 80 individual variants. The main constituent shapes for ice crystals, from which combinations may occur, are needle, column, plate, and rime. Snow appears white in color despite being made of clear ice. This is due to diffuse reflection of the whole spectrum of ligh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microscope
A microscope () is a laboratory instrument used to examine objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using a microscope. Microscopic means being invisible to the eye unless aided by a microscope. There are many types of microscopes, and they may be grouped in different ways. One way is to describe the method an instrument uses to interact with a sample and produce images, either by sending a beam of light or electrons through a sample in its optical path, by detecting photon emissions from a sample, or by scanning across and a short distance from the surface of a sample using a probe. The most common microscope (and the first to be invented) is the optical microscope, which uses lenses to refract visible light that passed through a thinly sectioned sample to produce an observable image. Other major types of microscopes are the fluorescence microscope, electron microscope (both the transmi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edo-period Works
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''. A revolution took place from the time of the Kamakura shogunate, which existed with the Tennō's court, to the Tok ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
