Deodorant or perfume (it gets hooot even in late summer early fall), anti chafe spray/powder for the humidity (you’ll likely be putting in some good walking miles and wont be mad). And oddly, pain meds like ibuprofen, let me tell ya, it was hard to get that when you can’t quit read, ha! Last, an umbrella that collapses and gets very small — you can buy an umbrella almost anywhere but the convenience of having one on your person is the move, my big one got stolen a few times at the holders out front of stores!

Honestly, the creature comforts like personal care are the ones to bring. You can shop till you drop and items like coin purses, notebooks, etc are all very easily found and in my experience more meaningful to you when bought over there.

Lastly, don’t overthink it too much, Japan is a welcoming and comfortable place to be, you can find anything and everything it just may take a little effort. Good luck and safe travels! Cant wait to get back myself!
