After Shimokitazawa and Shibuya we took the metro over to the Skytree, then after that took the water bus over to Odaiba (from Hinode station). This only cost ¥520, takes 20 minutes and you get an awesome view of the Rainbow bridge. Walked from the water bus terminal over to team labs (about 20 minute walk) and checked out the Toyota display. This was free.
Not really a great day, but the view was still ok
