I just received a notification from my next cruiseline to make sure I have enough blank pages in my passport. How many times was your passport stamped on the last 14 days of Japan ports? I appreciate you checking. On my last 18 day cruise it was stamped in 4 different ports. We had to turn in our passports the night before or day of the port, so we had no control if they stamped on a blank page or not. Certain countries require 1-2 blank pages. TIA
