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, parts of China, and various Pacific islands, locals in those countries were forced to learn Japanese in empire-building programmes. 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 Brazil, where the biggest Japanese community outside Japan is found, Australia (especially Sydney, Brisbane, and Melbourne), and the United States (notably California and Hawaii), 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.
