This is my proudest moment at Mt Fuji: the 2nd bright sunrise! (yes, the sun rises twice on that same morning lol)


A very good question, and I have a very good answer for you and everyone else:
YAMANOTE LINE 
Sauce:
http://en.wikipedia.org/wiki/Yamanote_Line
^ as you can see the route map of JR Yamanote Line, it goes to almost
ALL the popular places in Tokyo!
Shibuya, Shinjuku, Tokyo, Akihabara, Shimbashi (go down here to take a train to cross over the sea to the Odaiba Island), Ikebukuro, Harajuku, etc!
And, its an unending circle route, which means that if you will not get lost anywhere since it will always be going around in the same circle!

If you wanted to go to Akihabara but you overslept and thus overshot until the next station (lets say Kanda), don't worry!
Get down in Kanda, and take another Yamanote Line that goes the opposite way, back to Akihabara
