Japanese Gunboat Chiyodagata
was a gunboat of the Tokugawa Navy, and Japan's first domestically-built steam warship (Japan's first steamship was the built by the fief of Satsuma in 1855). She was a 3rd class wooden gunboat and laid down May 7, 1861, and launched July 2, 1863 by the shipbuilder, and future industrial giant, Ishikawajima. Completed in May 1866, She participated in the conflict of the Boshin War with the Bakufu loyalists, against the newly formed Imperial Army. She was captured during the Naval Battle of Hakodate Bay, and was grounded during the conflict. In May 1868 she was seized by the Japanese government, then captured by the rebels on 4 October 1868. Recaptured again by the Japanese government on 30 April 1869, she became a training ship until she was decommissioned on 28 January 1888.

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship's carrying capacity, as it excluded the small, often unusable volume contained in her overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall __NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured para ...

Length At The Waterline
A vessel's length at the waterline (abbreviated to L.W.L)Note: originally Load Waterline Length is the length of a ship or boat at the level where it sits in the water (the ''waterline''). The LWL will be shorter than the length of the boat overall (''length overall'' or LOA) as most boats have bows and stern protrusions that make the LOA greater than the LWL. As a ship becomes more loaded, it will sit lower in the water and its ambient waterline length may change; but the registered L.W.L it is measured from a default load condition. This measure is significant in determining several of a vessel's properties, such as how much water it displaces, where the bow and stern waves occur, hull speed, amount of bottom-paint needed, etc. Traditionally, a stripe called the "boot top" is painted around the hull just above the waterline. In sailing boats, longer waterline length will usually enable a greater maximum speed, because it allows greater sail area, without increasing beam or d ...

Gunboat
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies. History Pre-steam era In the age of sail, a gunboat was usually a small undecked vessel carrying a single smoothbore cannon in the bow, or just two or three such cannons. A gunboat could carry one or two masts or be oar-powered only, but the single-masted version of about length was most typical. Some types of gunboats carried two cannons, or else mounted a number of swivel guns on the railings. The small gunboat had advantages: if it only carried a single cannon, the boat could manoeuvre in shallow or restricted areas – such as rivers or lakes – where larger ships could sail only with difficulty. The gun that such boats carried could be quite heavy; a 32-pounder for instance. As such boats were cheap and quick to build, naval forces favoured swarm ...

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'' (f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satsuma Domain
The , briefly known as the , was a domain (''han'') of the Tokugawa shogunate of Japan during the Edo period from 1602 to 1871. The Satsuma Domain was based at Kagoshima Castle in Satsuma Province, the core of the modern city of Kagoshima, located in the south of the island of Kyushu. The Satsuma Domain was ruled for its existence by the '' Tozama'' ''daimyō'' of the Shimazu clan, who had ruled the Kagoshima area since the 1200s, and covered territory in the provinces of Satsuma, Ōsumi and Hyūga. The Satsuma Domain was assessed under the '' Kokudaka'' system and its value peaked at 770,000 '' koku'', the second-highest domain in Japan after the Kaga Domain. Totman, Conrad. (1993) ''Early Modern Japan'', p. 119 The Satsuma Domain was one of the most powerful and prominent of Japan's domains during the Edo period, conquering the Ryukyu Kingdom as a vassal state after the invasion of Ryukyu in 1609, and clashing with the British during the bombardment of Kagoshima in 186 ...

Boshin War
The , sometimes known as the Japanese Revolution or Japanese Civil War, was a civil war in Japan fought from 1868 to 1869 between forces of the ruling Tokugawa shogunate and a clique seeking to seize political power in the name of the Imperial Court. The war stemmed from dissatisfaction among many nobles and young samurai with the shogunate's handling of foreigners following the opening of Japan during the prior decade. Increasing Western influence in the economy led to a decline similar to that of other Asian countries at the time. An alliance of western samurai, particularly the domains of Chōshū, Satsuma, and Tosa, and court officials secured control of the Imperial Court and influenced the young Emperor Meiji. Tokugawa Yoshinobu, the sitting ''shōgun'', realizing the futility of his situation, abdicated and handed over political power to the emperor. Yoshinobu had hoped that by doing this the House of Tokugawa could be preserved and participate in the future gover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bakufu
, officially , was the title of the military dictators of Japan during most of the period spanning from 1185 to 1868. Nominally appointed by the Emperor, shoguns were usually the de facto rulers of the country, though during part of the Kamakura period, shoguns were themselves figureheads, with real power in hands of the Shikken of the Hōjō clan. The office of shogun was in practice hereditary, though over the course of the history of Japan several different clans held the position. The title was originally held by military commanders during Heian period in the eighth and ninth centuries. When Minamoto no Yoritomo gained political ascendency over Japan in 1185, the title was revived to regularize his position, making him the first shogun in the usually understood sense. The shogun's officials were collectively referred to as the ; they were the ones who carried out the actual duties of administration, while the Imperial court retained only nominal authority.Beasley, William G ...

Imperial Japanese Army
The was the official ground-based armed force of the Empire of Japan from 1868 to 1945. It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army, both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the Imperial Japanese Navy. Later an Inspectorate General of Aviation became the third agency with oversight of the army. During wartime or national emergencies, the nominal command functions of the emperor would be centralized in an Imperial General Headquarters (IGHQ), an ad hoc body consisting of the chief and vice chief of the Army General Staff, the Minister of the Army, the chief and vice chief of the Naval General Staff, the Inspector General of Aviation, and the Inspector General of Military Training. History Origins (1868–1871) In the mid-19th century, Japan had no unified national army and the country was made up of feudal domains (''han'') with the Tokugawa shogunate (''bakufu ...

Naval Battle Of Hakodate Bay
The was fought from 4 to 10 May 1869, between the remnants of the Tokugawa shogunate navy, consolidated into the armed forces of the rebel Ezo Republic, and the newly formed Imperial Japanese Navy. It was one of the last stages of Battle of Hakodate during the Boshin War, and occurred near Hakodate in the northern Japanese island of Hokkaidō. Ezo Republic forces The naval forces of the Ezo Republic were grouped around the warship ''Kaiten''. The fleet originally consisted of eight steamships: ''Kaiten'', ''Banryū'', Japanese gunboat '' Chiyoda'',Jentschura p. 113 ''Chōgei'', ''Kaiyō Maru'', ''Kanrin Maru'', ''Mikaho'' and ''Shinsoku''. However, ''Kaiyō Maru'' and ''Shinsoku'' had been lost in a previous engagement in front of Esashi, and ''Kanrin Maru'' had been captured by Imperial forces after suffering damage in bad weather. The loss of these three major units seriously weakened the Ezo Republic side. Imperial forces For the operation, an Imperial Japanese N ...

Whaling Ship
A whaler or whaling ship is a specialized vessel, designed or adapted for whaling: the catching or processing of whales. Terminology The term ''whaler'' is mostly historic. A handful of nations continue with industrial whaling, and one, Japan, still dedicates a single factory ship for the industry. The vessels used by aboriginal whaling communities are much smaller and are used for various purposes over the course of the year. The ''whale catcher'' was developed during the age of steam, and then driven by diesel engines throughout much of the twentieth century. It was designed with a harpoon gun mounted at its bow and was fast enough to chase and catch rorquals such as the fin whale. At first, whale catchers either brought the whales they killed to a whaling station, a settlement ashore where the carcasses could be processed, or to its factory ship anchored in a sheltered bay or inlet. With the later development of the slipway at the ship's stern, whale catchers were able to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
