>>2911762OP, I realize being in Japan is all exciting and stuff and you want to relay your excitment of awesome to the rest of us, but these pictures just don't do it.
Almost every image you posted here is tourist snapshit tier, and not even even interesting tourist-snapshit tier.
Your main issue (aside from only photographing people's backs) is that your composition is pretty bad. You center your subjects when not appropriate in some phots, but probably most annoying you have a strong habit to cut off elements in the image at odd places, creating an unpleasant or unbalanced feel.
Your colors are also feel SOOC (in a bad way, don't know if they actually are) and make for a pretty dull atmosphere. Cities in japan can be pretty vibrant and characterful, but your images show nothing of this.
Also, as somebody else said, curate your images more. Post your 5 best pictures. Even better if you can actually tell why you like them.
Personally when I'm traveling, I have a habit of just snapshitting a lot, because foreign environments are interesting, and I like documeting that stuff for myself. But I don't entertain the idea that most other people would find those images very interesting, because usually they are pretty snapshitty.
For example, last time I was in Japan I probably took 1000+ snapshits, "saved" probably 300 of those for myself, but would probably consider ~15 of them to actually be "decent" enough to put up here, and of those for maybe ~5 to be actually honest to good images. YMMV, of course - this is how I work.
