Saga, a city of Japan, in the province of Hizen, at the head of the bay of Shimabara, island of Kiushiu; pop. about 100,000. It is regularly laid out, the streets crossing at right angles, is the principal seat of the trade of Kiushiu, and manufactures the famous Hizen porcelain ware. It has an ancient castle, a telegraph station, and government schools. It was the former capital of the prince of Na-beshima, one of the 18 semi-independent dai-mios, and the scene of much active labor by Jesuit missionaries in the 16th and 17th centuries. In 1872 it was the centre of a party which took up arms to compel the resignation of the Tokio cabinet, and the acqniescence of the government in the projected invasion of Corea. This rebellion was suppressed in a few days, several regiments of the national army in government transports and chartered American steamers arriving at Saga, and after a battle and some skirmishing restoring the authority of the central government. The principal leader and 13 others, including two students educated abroad, were decapitated; 195 persons were condemned to various punishments; more than 7,500 insurgents surrendered; and 50 villages in the vicinity and about 1,000 houses in Saga were burned.
