for foreign nationals working in Japan
For a foreign national to work in Japan, their status of residence must permit them to work. Anyone in violation of this will be working illegally and be subject to punishment. For example, status of residence such as "Student" and "Dependent" do not allow one to work, but if you receive "Permission to Engage in Activity other than that Permitted under the Status of Residence Previously Granted" from the Immigration Services Agency, it is possible to work a part-time job for a limited amount of hours. Even for someone whose status of residence allows them to work, if they want to engage in work outside the field of that allowed by their status of residence (for example: receiving pay for interpreting under a Skilled Labor status of residence), they will need "Permission to Engage in Activity other than that Permitted under the Status of Residence Previously Granted".
