Enjoy different types of food, go to bars and Izakayas, get the spectacular night view.
There are beautiful temples and shrines in Tokyo, too but if you talk about shrines and temples, Kyoto is much better. I think the attractions of Tokyo is city. Experience delicious cuisines (some of them very expensive!) and shopping, fashionable bars and cafes. Or maybe visit museums and go to theaters to see Kabuki performances, etc.
