Concept
Japonic languages
Summary
Japonic or Japanese–Ryukyuan, sometimes also Japanic, is a language family comprising Japanese, spoken in the main islands of Japan, and the Ryukyuan languages, spoken in the Ryukyu Islands. The family is universally accepted by linguists, and significant progress has been made in reconstructing the proto-language. The reconstruction implies a split between all dialects of Japanese and all Ryukyuan varieties, probably before the 7th century. The Hachijō language, spoken on the Izu Islands, is also included, but its position within the family is unclear.
Most scholars believe that Japonic was brought to the Japanese archipelago from the Korean peninsula with the Yayoi culture during the 1st millennium BC. There is some fragmentary evidence suggesting that Japonic languages may still have been spoken in central and southern parts of the Korean peninsula (see Peninsular Japonic) in the early centuries AD.
Possible genetic relationships with many other language families have been proposed, most systematically with Koreanic, but none have been conclusively demonstrated.
The extant Japonic languages belong to two well-defined branches: Japanese and Ryukyuan.
Most scholars believe that Japonic was brought to northern Kyushu from the Korean peninsula around 700 to 300 BC by wet-rice farmers of the Yayoi culture and spread throughout the Japanese archipelago, replacing indigenous languages.
The former wider distribution of Ainu languages is confirmed by placenames in northern Honshu ending in -betsu (from Ainu pet 'river') and -nai (from Ainu nai 'stream').
Somewhat later, Japonic languages also spread southward to the Ryukyu Islands. There is fragmentary placename evidence that now-extinct Japonic languages were still spoken in central and southern parts of the Korean peninsula several centuries later.
Japanese language
Japanese is the de facto national language of Japan, where it is spoken by about 126 million people. The oldest attestation is Old Japanese, which was recorded using Chinese characters in the 7th and 8th centuries.
