I am traveling from Haneda to Narita and pretty much mostly in Tokyo - Shinjuku, Roppongi, Toyosu, Nihonbashi, Harajuku.... can't remember where else... maybe yokohama or koto (near Toyosu). I want to use the monorail and local buses/trains. I will be there for about 6-7 days. Which pass should I get? I have read about the JR East pass and the regular JR Pass and feel more confused than ever. Can someone please give me some advice.
