Japanese language
The Japanese language () is the official language of Japan, in East Asia. Japanese belongs to the Japonic language family, which also includes the endangered Ryukyuan languages. One theory says Japanese and Korean are related, but most linguists no longer think so. Other theories about the origin of Japanese are that it is related to the Austronesian languages, the Dravidian languages, or the controversial Altaic language family. The term used for Japanese as a course of study by citizens is "kokugo" (国語), which means national language. Nonetheless, Japanese is still referred to as Nihon-go by the Japanese.
