Han school
The was an educational institution in the Edo period of Japan, originally established to educate children of "daimyōs" (feudal lords) and their retainers in the domains outside of the capital. These institutions were also known as "hangaku" (), "hangakkō" () or "hankō" (). These schools existed until 1871, when the domains were abolished after the Meiji Restoration of 1868. The "han" schools were at first narrowly defined as schools of Confucian studies for the cultivation of the samurai elite, and attendance was both expected of and limited to the children of this class. Late in the period, however, children of other  social classes were permitted to attend, and the curriculum was expanded from its core in the Confucian classics to include training in classical Japanese studies ("kokugaku)," medicine, and the various branches of Western learning, including mathematics, astronomy, military science, and ballistics. Students entered at age 7 or 8 and usually completed their courses of study between the ages of 15 and 20. By the 1860s there were about 255 "han" schools nationwide. The "han" schools, which predominated in provincial regions, were similar to and paralleled the "terakoya" or "temple-school" system of education which was more prominent in the major  urban centers of the capital, Edo, and Osaka and Kyoto. The major difference between two systems was that "hanko" were state institutions organized by the local domain government, and "terakoya" were private institutions organized by local Buddhist temples. Some of the more famous han schools included Nisshinkan (Aizu), Kōdōkan (Mito), Meirindō (Sendai), Meirinkan (Hagi, Yamaguchi) and Jishūkan (Kumamoto).
