I purchased tickets in advance for the things I had to see--Sumo and baseball--and also starred a bunch of things I was interested in in Google Maps.

Then as I navigated around the city I could see what was nearby and decide if I wanted to visit or not.

It's a great city for walking and wandering--things to see and do everywhere.

And if you decide you want to switch neighbourhoods, the subway is always nearby and easy to use.
