I'm visiting Tokyo next week and will be arriving at Haneda. I know that the monorail goes straight to Minato but what card will I need to ride the monorail. I have researched a bit and found Suica/Pasmo but can they be used on the Monorail? Once I'm in Tokyo will the Suica/Pasmo be sufficient to get me round all the different districts on the underground? Can I buy the Suica/Pasmo at Haneda?
