日本語はいくつの方言に分かれる
The dialects of the Japanese language fall into two primary clades, Eastern (including Tokyo) and Western (including Kyoto), with the dialects of Kyushu and Hachijō Island often distinguished as additional branches, the latter perhaps the most divergent of all. The Ryukyuan languages of Okinawa Prefecture and the southern islands of Kagoshima Prefecture form a separate branch of the Japonic family, and are not Japanese dialects, although they are sometimes referred to as such.
