Coastal Artillery
Coastal artillery is the branch of the armed forces concerned with operating anti-ship artillery or fixed gun batteries in coastal fortifications. From the Middle Ages until World War II, coastal artillery and naval artillery in the form of cannons were highly important to military affairs and generally represented the areas of highest technology and capital cost among materiel. The advent of 20th-century technologies, especially military aviation, naval aviation, jet aircraft, and guided missiles, reduced the primacy of cannons, battleships, and coastal artillery. In countries where coastal artillery has not been disbanded, these forces have acquired amphibious capabilities. In littoral warfare, mobile coastal artillery armed with surface-to-surface missiles can still be used to deny the use of sea lanes. It was long held as a rule of thumb that one shore-based gun equaled three naval guns of the same caliber, due to the steadiness of the coastal gun which allowed for ...

Perry Expedition
The Perry Expedition ( ja, 黒船来航, , "Arrival of the Black Ships") was a diplomatic and military expedition during 1853–1854 to the Tokugawa Shogunate involving two separate voyages by warships of the United States Navy. The goals of this expedition included exploration, surveying, and the establishment of diplomatic relations and negotiation of trade agreements with various nations of the region; opening contact with the government of Japan was considered a top priority of the expedition, and was one of the key reasons for its inception. The expedition was commanded by Commodore Matthew Calbraith Perry, under orders from President Millard Fillmore. Perry's primary goal was to force an end to Japan's 220-year-old policy of isolation and to open Japanese ports to American trade, through the use of gunboat diplomacy if necessary. The Perry Expedition led directly to the establishment of diplomatic relations between Japan and the western Great Powers, and eventually to the ...

Rangaku
''Rangaku'' (Kyūjitai: /Shinjitai: , literally "Dutch learning", and by extension "Western learning") is a body of knowledge developed by Japan through its contacts with the Dutch enclave of Dejima, which allowed Japan to keep abreast of Western technology and medicine in the period when the country was closed to foreigners from 1641 to 1853 because of the Tokugawa shogunate's policy of national isolation (sakoku). Through Rangaku, some people in Japan learned many aspects of the scientific and technological revolution occurring in Europe at that time, helping the country build up the beginnings of a theoretical and technological scientific base, which helps to explain Japan's success in its radical and speedy modernization following the forced American opening of the country to foreign trade in 1854. History The Dutch traders at Dejima in Nagasaki were the only Europeans tolerated in Japan from 1639 until 1853 (the Dutch had a trading post in Hirado from 1609 till 1641 bef ...
