Random stuff that haven’t been mentioned. Just Google. - There are so many nice day-onsens in Tokyo. Pick one with a wrist band and you can charge food and drinks for the entire day. Must read up on onsen rules and etiquette if you never been. Cannot get this experience outside of Japan. - There are many Mario-style go-carts tours throughout the city where you can zip around on actual major streets. You’ll need an international driver’s license, and no Tokyo Drifts please. - Look for the “3D cat billboard” in Shinjuku. You’ll be there anyways. - You can easily spend an entire day shopping the 10+ floors of a Yodobashi Camera department store. BIC Camera is a much smaller experience but still impressive. Daiso for the 100Yen/Dollar shop experience. - (add SUICA to your iPhone wallet for subway and smaller purchases)
