Classification
See also: Classification of JaponicJapanese is a member of the Japonic languages family, which also includes the languages spoken throughout the Ryūkyū Islands. As these closely related languages are commonly treated as dialects of the same language, Japanese is often called a language isolate, but strictly speaking this is a misnomer, since the Ryukyuan languages are linguistically distinct.
According to Martine Irma Robbeets, Japanese has been subject to more attempts to show its relation to other languages than any other language in the world. Since Japanese first gained the consideration of linguists in the late 19th century, attempts have been make to show its genealogical relation to languages or language families such as Ainu, Korean, Chinese, Tibeto-Burman, Ural-Altaic, Altaic, Uralian, Mon–Khmer, Malayo-Polynesian and Ryukyuan. At the fringe, some linguists have suggested a link to Indo-European languages, including Greek, and to Lepcha. As it stands, only the link to Ryukyuan has wide support, though linguist Kurakichi Shiratori maintained that Japanese was a language isolate.
