Japanese (Japanese: 日本語; Nihongo)is a language spoken by over 127 million people, mainly in Japan, but also by Japanese emigrant communities around the world. It is considered an agglutinative language and is distinguished by a system of honorifics reflecting the hierarchical nature of Japanese society, with verb forms and particular vocabulary which indicate the relative status of speaker and listener. The sound inventory of Japanese is relatively small, and it has a lexically-distinctive pitch accent system.

Japanese has been heavily influenced by Chinese over a period of at least 1,500 years. Japanese is written with a mix of Chinese characters (kanji) and a modified syllabary, kana, also originally based on Chinese characters. Much vocabulary has been imported from Chinese, or created on Chinese models.
