Has Japanese PR gotten worse? This European is telling everyone how great Japan was. He's either an aspie or its a Japanese Public Relations post

I have been on on exchange living in Japan and I must say I have been impressed and felt very very very welcome here. Have never felt this way in any country (maybe not even my own). I am heading back now unfortunatly.

Apart from all the good food, nature etc. The things that I have noticed and really appreciated was:

Never had a conflict with anyone here. Not a single one (yes, it is obvious I am not Japanese, so I guess locals will be more accepting, but still).
Everyone seems to be very mindful of others and things are so clean and orderly. No one is loud, take up space etc. And no one minds you (people dont stare at you or comment on what your doing).
Japanese people would ask if I needed help on train stations etc. * Very kind people ! It has been very easy to meet locals and I have made good friends (maybe not on tatemae level?).
Overall, sitting in the airport, I already feel the European/western loudness, taking up space, clumsiness etc. … Very uncharming to observe actually comming straight from Japanese living.

I know I probably have some of the traits myself (as I grew up in it) but I am almost a bit affraid to return to all the random people creating conflicts, loud and obnoxious people etc.

Anyone who can comment on things that might help ? I have already tried to find Tonkotsu ramen places (hahah!) in my city and other Japanese things that might make me feel more at ease. Non the less, thank you Japan for an absolutely amazing experince here !
