This article deals with Japanese as it relates to NationStates. For more general information, see the Wikipedia article on this subject.
Although Japanese is spoken almost exclusively in Japan, it has been and is still sometimes spoken in countries besides Japan. When Japan occupied Korea, Taiwan and parts of China, locals in those countries were forced to learn Japanese and in Korea people were given a Japanese name. As a result, there are still many people in these countries who speak Japanese instead of or as well as the local languages. In addition, emigrants from Japan, the majority of whom are found in the United States (notably California and Hawaii), and Brazil also frequently speak Japanese. There is also a small community in Davao, Philippines. Their descendants (known as nikkei 日系, literally Japanese descendants), however, rarely speak Japanese fluently. There are estimated to be several million non-Japanese studying the language as well.
