Japanese (Nihongo) is a language spoken by over 130 million people, mainly in Japan, but also by Japanese emigrant communities around the world. It is an agglutinative language and is distinguished by a complex system of honorifics reflecting the hierarchical nature of Japanese society, with verb forms and particular vocabulary to indicate the relative status of speaker, listener and the person mentioned in conversation. The sound inventory of Japanese is relatively small, and has a lexically distinct pitch-accent system.
