Black ShipsThe Black Ships (in 黒船, Edo period term) was the name given to Western vessels arriving in Japan in the 16th and 19th centuries. In 1543 Portuguese initiated the first contacts, establishing a trade route linking Goa to Nagasaki. The large carracks engaged in this trade had the hull painted black with pitch, and the term came to represent all Western vessels. In 1639, after suppressing a rebellion blamed on the influence of Christian thought, the ruling Tokugawa shogunate retreated into an isolationist policy, the Sakoku.
Chōnin町人 was a social class that emerged in Japan during the early years of the Tokugawa period. In the social hierarchy, it was considered subordinate to the samurai warrior class. The chōnin emerged in joka-machi or castle towns during the sixteenth century. The majority of chōnin were merchants, but some were craftsmen. 農民 were not considered chōnin. Later, peasants, servants, and workers were also considered members of the social class.
Christianity in JapanChristianity in Japan is among the nation's minority religions in terms of individuals who state an explicit affiliation or faith. Between less than 1 percent and 1.5% of the population claims Christian belief or affiliation. Although formally banned in 1612 and today critically portrayed as a foreign "religion of colonialism", Christianity has played a role in the shaping of the relationship between religion and the Japanese state for more than four centuries.
KokugakuKokugaku (國學, 国学; literally "national study") was an academic movement, a school of Japanese philology and philosophy originating during the Tokugawa period. Kokugaku scholars worked to refocus Japanese scholarship away from the then-dominant study of Chinese, Confucian, and Buddhist texts in favor of research into the early Japanese classics. What later became known as the kokugaku tradition began in the 17th and 18th centuries as kogaku ("ancient studies"), wagaku ("Japanese studies") or inishie manabi ("ancient studies"), a term favored by Motoori Norinaga and his school.
