Re-enter Japan as tourist

I'm ending my employment contract end of this year and will be surrendering my resident card when I leave Japan to visit my family end of Dec , but will be returning to Japan in Jan as a tourist with my Passport to tight some some loose ends (and leave again for good in Feb). Will there be any concerns with immigration with such arrangement? will there be a problem having a returning ticket when I surrender my resident card at immigration? is there any (time,etc) limit as to when people can re-visit the country after surrendering their resident card?

I cannot see why this would be a problem or even an issue. You are returning as a tourist/short stay, not intending to work. Do you need a visa to enter Japan or on the waiver programme?
