It has around 123 million speakers, primarily in Japan, the only country where it is the national language, and within the Japanese diaspora worldwide. The Japonic family also includes the Ryukyuan languages and the variously classified Hachijō language. https://en.wikipedia.org/wiki/Japanese_language
