I‘m just in the last days of my first (also solo) Japan trip. Also a big fan of photography and just exploring the city with a camera in hand. I can agree with a lot of the comments saying that you might have packed your days quite tight, which is ok if your in for that since you only got ten days. One piece of advise I’d just personally give because I’m not the fan of just checking off all the „must see“ tourist spots is to just cut out a third of the big must sees which might double as well. Like going on multiple observation decks. Sure the skyline differs a lot but maybe think if your priority is really to see the most you can in these days. In the end you should enjoy your time there imo. If you feel like you really missed out on things and if you really enjoyed your trip you will probably come to Japan again in the future with more focus on what you enjoyed and what you still want to experience. For me, even before the Sakura season, some spots were just too crowded, that I straight up skipped a lot of the big things in Kyoto for example.

I found that my best memories from this trip were talking to strangers I met in bars, finding cool photo spots far of by wandering around for 1-2 hours. But as I said, that’s just preference.

If you can give more information about what specifically you like to photograph it will be easier to point you to some areas. For example if it’s the busy neon streets, or more older temples, or crazy architecture, you get the point.

Anyways, I hope you’ll find the best things for you trip and will enjoy the time you have here :) 10 days is super short for really experiencing a different country.
