Most importantly i'm taking my girlfriend along and would like to be a romantic, anyone know the romantic places in Tokyo? ;-)
[B]Tokyo Tower- The japanese version of the Eiffel Tower. Romantic at night i would say. & also the Rainbow Bridge to Odaiba. Roppongi Hills?
Roppongi Hills would be better than the Tokyo Tower, I'd say. It's taller - and you get a trip to a museum thrown in. And you can have dinner at some fancy restaurants.
Or find a nice onsen with "family" baths.
