Go-on

Template:Short description 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 , preceding the readings. Both go-on and kan-on exhibit characteristics of Middle Chinese.

History and uses

Kentoshi route, also known as the sea route from Japan to China

Go-on readings were introduced into Japan during the 5th and 6th centuries, when China was divided into separate Northern and Southern dynasties. They may have been imported either directly from the Southern dynasty or from the Korean Peninsula. There was an influx of thinkers from China and Korea to Japan at that time, including practitioners of both Buddhism and Confucianism. However, there is no historical documentation to demonstrate that go-on readings are actually based on Southern Chinese.

Shibatani has noted that go-on readings make up the first of three waves of Chinese loans to the Japanese language, the others being kan-on and tou-sou-on (meaning Tang Song sound), with go-on being mainly associated with Buddhism.

Go-on readings are particularly common for Buddhist and legal terminology, especially those of the Nara and Heian periods. These readings were also used for the Chinese characters of the ancient Japanese syllabary used in the Kojiki.

When kan-on readings were introduced to Japan, their go-on equivalents did not disappear entirely. Even today, go-on and kan-on readings still both exist. Many characters have both readings. For instance, the name Shōtoku (which is go-on) is pronounced as such in some derived placenames, but as Seitoku (which is kan-on) in others.

However, some go-on sounds are now lost. Even though monolingual Japanese dictionaries list a complete inventory of go-on for all characters, some were actually reconstructed using the fanqie method or were inferred to be the same as their modern homophones.

Names

Go-on readings were formerly referred to as . The term 'go-on' was first introduced in the mid-Heian, likely by people who wished to promote kan-on readings. During the Tang dynasty, people in Chang'an referred to their own way of reading characters as and all other readings, particularly those originating south of the Yangtze, as or one of many other similar names. It is thought that Japanese students studying in China adopted this practice, and, taking the position that the Chang'an-based manner of elocution were the correct ones, they also began to refer to the previously imported, unfashionable kanji readings as "go-on".

Go-on readings were also occasionally referred to as and because of a story that claims a Baekjean nun named had taught Buddhism in Tsushima by reading the Vimalakīrti Sutra entirely in go-on.

Characteristics

Go-on readings are generally less orderly than kan-on readings, but can be characterized as follows.

• voiced consonants in Middle Chinese were distinguished from unvoiced consonants when they occurred in syllable-initial positions.
• Syllable-initial nasal consonants are pronounced as nasals (m-, n-) in Middle Chinese, but in kan-on, they are interpreted as voiced plosives (b-, d-).
• In some characters, -o and -u are both acceptable and widespread, e.g., 素 (so, su), 奴 (do, nu) and 都 (to, tsu).
