Recently I've spent a couple of months in Japan on a WHV. Upon arrival I registered my address within the first 14 days, however, when I had to leave the country I forgot to unregister it. The day I left, in the airport, I filled in the form that would allow me to come back with that same visa whenever I'd want to (within the year). To this day it's still within the valid period, given that the year is not over.
Now, when I need to process an actual work visa, will this be a conflict of any sort? If it will really be a problem, I still am able to go to japan and unregister my address and then come back to my country, where I currently am now (and end the WHV in the airport by giving up my zairyu card), but obviously that would be so wasteful in terms of time and money and I'd like to avoid that if necessary.
