Japanese is not related to any of the world's major language families, so it is a completely separate language, although it has phonetic, morphological and syntactic similarities with Korean. Japanese has also adopted some words from Chinese, however, it remains completely different from Chinese in pronunciation and grammar. Its origin and incorporation remain unexplained. It is spoken by about 127 million people, of whom about 800,000 live outside Japan.
The Japanese standard language originates from the dialect spoken in Tokyo and is also taught in the education system and disseminated through the media. There are many dialects in Japan, which evolved through the extensive settlement of Japan.
