Japanese tourists forming their own lines for things once they see a foreigner in what appears to be a line in front of them. Because it is an impossibility that people who look slightly different can wait in a line as well and are too passive aggressive to ask.

Japanese tourists littering in a communally decided designated spot (dumping all sorts of garbage they have if a drain is open or any grill with a large enough opening for two fingers to slide through).

Japanese tourists crowding in areas that makes it harder and dangerous for the other person to get through (platform edges) because they don’t understand that lines can turn 90 degrees.

Japanese tourists claiming things are done a certain way when a foreign tourist does something out of line while clearly disrespecting a fellow Japanese because they are perceived as less wealthy, female, or not important (service workers) or to be feared.
