Specified Skilled Worker(SSW) is a type of residency intended to widen the employment options for foreign nationals in Japan. Citizens who can work as an SSW in Japan must be over the age of 18, in good health, have the requisite occupational abilities, and be able to work immediately without any special training. A uniform exam administered by Japan will validate skills and Japanese ability. In essence, you can work for up to 5 years, but you cannot bring your family. Furthermore, the main difference between other kinds of residency to work in Japan is a support system.
