Go-on (呉音), which is one of the sources of Japanese pronunciation for Chinese characters (the others being kan-on, tō-on and kan'yō-on), was Jinling Standard Pronunciation, the standard Chinese of time that spread to Japan during Southern dynasties. The "Go-" component in the name "Go-on" is cognate to the Chinese word "Wu" (Wu is the pronunciation for the glyph 吳 in Mandarin. However, in today's Wu language 呉 is usually pronounced as "Ho", "Oh", "Ng", or "Nguu").
