It honestly really depends what you're into and the kind of person you are.
For me I hit the usual touristy places like Shibuya crossing, Shinjuku Garden, Akihabara, etc.
But I also love baseball, so I went and caught a Yomiuri Giants game at Tokyo Dome. Even if you're not a baseball fan, it is super cool seeing how differently they participate as a crowd of fans at games. I also enjoy just walking around neighborhoods, so I spent time just taking the train to different areas and exploring the lesser-known areas that tourists don't commonly visit. I love car-related stuff, so I rented a car for a few days and went to some popular car-related places.
There are also plenty of food spots you can visit depending on what tastes you have. Cheap or more expensive.
There are fun areas like Odaiba City/Beach (with its own Statue of Liberty statue, smaller scale and a Gundam suit thing near the shopping mall).
If you plan during a specific season, like spring, you can go to find the cherry blossoms. Spring is usually incredibly crowded because of that, but with the right planning you can somewhat beat the crowds to certain popular spots (or find unknown spots that tourists won't visit but still have many blossoms).
