The han school was a type of educational institution in the Edo period of Japan. They taught samurai etiquette, the classical Confucian books, calligraphy, rhetoric, fighting with swords and other weapons; some also added subjects such as medicine, mathematics and Western sciences. Schools in different han (domains) provided different curricula and had varied conditions for entry. Over the course of the Edo period, han schools evolved from simple one-room schools to large educational facilities with multiple buildings. The total numbers of han schools varied from several dozen in the early 17th century to over 250 by the end of the 19th century.
