Japan's national broadcaster produces a good range of English-language programmes and news, but did you know they also offer free online language resources? The language homepage is handy in that its lessons are divided according to proficiency levels – beginner, elementary, intermediate – and are supplemented with videos, textbook downloads, learning tools, and even podcasts – all of which are free.
The website also has specialised lessons such as the 'Easy Japanese for Work', which teaches you phrases and kanji characters useful for working in a Japanese environment. Tourists, on the other hand, will benefit greatly from 'Easy Travel Japanese'.
