I currently hold a five year Engineer/Specialist in humanities visa and am working for a Japanese company. I’m interested in the possibility of reducing my hours for the Japanese company to 20 hours, and working remotely for a foreign company for 20 hours per week. My foreign income would like exceed my salary from the Japanese company.
Would this kind of an activity be within the scope of my current visa? Getting my visa renewed is not a particular concern at the moment as I don’t have plans to stay longer than five years.
