1) Get a nice pair of running shoes. You’ll be walking 10k+ steps 2) Convenient stores 3) Stand on the Right side on escalator if you’re in Tokyo (clarify me if I’m wrong) 4) Try things when you see you want to eat 5) Check out Klook for any tours or special items and 72 hrs pass y rain ticket within Tokyo 6) Get International driving license in case you want to try Go-Karting on busy streets of Tokyo 7) Credit card that can save points or no transaction fee on your trip… don’t get AMEX

If you want to see Sakura, I recommend to go to Yoshino. In Yoshino people can see Sakura for 3 weeks.
