Tamagawa Aqueduct
is a 43 km long Japanese aqueduct located in Tokyo. It was constructed by the Tokugawa shogunate to supply drinking and fire-fighting water from the Tama river to Edo, providing irrigation water around farm villages. The aqueduct was made following a request for permission from the people of Kojimachi and Shibaguchi to build another aqueduct, drawing the waters of the Tama river. The government provided 7,500 ryō for the construction, 3,000 ryō were collected by public subscription. Construction on the 43 km long aqueduct, which runs from Hamura, Tokyo to Yotsuya, Tokyo, began in April 1653. The section from Hanemura to was fully excavated within eight months and the entire aqueduct was completed in eighteen months. The project was undertaken by the Seiemon brothers who were awarded the surname "Tamagawa" in honour of their accomplishment.

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aqueduct (water Supply)
An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term ''aqueduct'' is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term ''aqueduct'' also often refers specifically to a bridge carrying an artificial watercourse. Aqueducts were used in ancient Greece, ancient Egypt, and ancient Rome. The simplest aqueducts are small ditches cut into the earth. Much larger channels may be used in modern aqueducts. Aqueducts sometimes run for some or all of their path through tunnels constructed underground. Modern aqueducts may also use pipelines. Historically, agricultural societies have constructed aqueducts to irrigate crops and supply large cities with drinking water. Etymology The word ''aqueduct'' is derived from the Latin words (''water'') and (''led'' or ''guided''). Ancient aqueducts Although particularly associated with the Romans, aqueducts ...

(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.

Ryō
The was a gold currency unit in the shakkanhō system in pre- Meiji Japan. It was eventually replaced with a system based on the '' yen''. Origins The ''ryō'' was originally a unit of weight from China, the ''tael.'' It came into use in Japan during the Kamakura period. By the Azuchi–Momoyama period it had become nearly uniform throughout Japan, about 4.4 ''monme'' as a unit of weight (about the same as 16.5 grams). During the Sengoku period, various local ''daimyō'' began to mint their own money. One of the best known and most prestigious of these private coins was the ''koshukin'' issued by the warlord Takeda Shingen, who had substantial gold deposits within his territories. The value of the koshukin was based on its weight, with one ''koshukin'' equal to one ryō of gold, and thus stamped with its weight (about 15 grams). During the Tenshō period (1573–1592), one ryō was equal to four ''koku'' of rice, or 1000 brass coins. Tokugawa period The Tokugawa shogunate ...
