Go-on or goon (呉音; English: /ˈɡoʊ.ɒn/ GOH-on; Japanese pronunciation: [ɡo.oɴ] or [ɡoꜜoɴ], "sounds from the Wu region") are Japanese kanji readings based on the classical pronunciations of Chinese characters of the historically prestigious eastern Jiankang (now Nanjing) dialect.
Go-on are the earliest form of on'yomi (音読み), preceding the kan-on (漢音) readings. Both go-on and kan-on exhibit characteristics of Middle Chinese.
