I live in Japan and this happens to me all the time. My name is too long to fit in most forms so I have to drop the middle name (which isn’t really a thing here, they consider it as part of my first name), and then they get mad at me because it doesn’t match my ID exactly. I’ve had to redo forms because I didn’t write my name in all caps like the resident card. I’ve had medical ID cards from hospitals that chop my name halfway off and the staff wrote the rest with a marker. It’s a mess.
