I am popping back to the Land of the Rising Sun to keep my permanent residency still active by getting my reenty stamp, mine expires in a few months what's the maximum I can get- is it five or seven years? Also, looking at my residence card it says the period of validity of the card expires on 20th Feb 2020. Do i need to get a new card as well as reentry stamp? Because I might not be coming back to Japan until 2022 or 2024. On the card my period of stay/date of expiration has stars on it which means unlimited, but that's referring to my permanent residency not validity of the card.
