I know it's been over 5 years but wanted to bump this, has anyone had any actual experience with trying to enter Japan/notify PPU or their intent to travel? As far as I'm aware I don't need permission, just to notify them with over a weeks' notice, so I'm not sure if they're able to do anything, so would love to hear other people's experience.
Japan has always been somewhere I've dreamed about going, and being on an indefinite SHPO I'm not sure when I'll be free of that burden.
