Wow all these comments of the tourists (I assume) behaviors are no biggie and the person who filmed them is the problem! Wow wow wow these are the reason why local Japanese hating tourists now and you getting the not so good services. Not sure in which countries talking loud in a public transport (or singing or clapping whatever) is not a problem to others but sure IT IS a problem to Japanese. Is it so hard to RESPECT others culture to some people? Or you feel so entitled to be yourself ?!
