Sounds like you are already getting a great list going! I think Tokyo is one of those city’s that even if you don’t know what to do, if you just walk in any direction you will find something so interesting. I remember once I went into some 7/11 kind of place there and even there they had these amazing rice things with fish inside and it was SOOOO GOOD! Then the guy working there told me they are maid fresh every morning!!!
