Kan-on (漢音, Japanese pronunciation: [kaꜜɰ̃.oɴ] or [kaɰ̃.oɴ], "Han sound") is one of the sources of pronunciation of Japanese kanji. They were borrowed during the Tang dynasty (7th to 9th century), introduced by, among others, envoys from Japanese missions to Tang China. This period corresponds with the Japanese Nara period. Not to be confused with Tō-on "Tang sound", which actually refers to later phonetic loans. Kan'on partly displaced the earlier go'on, which were "just imitations of Korean imitations, but Kan-on were imitations of the real things."
