how to use our language skills?
In most cases in order to work full time in Japan you need to have a University degree and you also require the backing of a company in Japan to sponsor your visa. There are about a dozen types of working visas available, each allowing the holder to work only within a defined professional field, e.g. as an engineer, instructor or entertainer. It is very easy to obtain a tourist visa (temporary visa) but this lasts only 90 days and can only be extended under special circumstances. Please note that it is not permitted to engage in any paid activities on a tourist visa.
Many foreign residents from English speaking countries now work in Japan, most as language instructors. The demand for native language instructors remains high, with a lot of major language schools now operating recruitment offices overseas. It is quite easy to find work teaching in Japan.
