Hi Uji-san, thanks for replying! I've checked on the NEX&Suica. I'm staying in the Ueno area and know the NEX does not go directly there. If I do buy that, I will have to transfer from Tokyo station right - will that cost much?
Since I will be touring Tokyo on day 2, I am also considering using the Keisei (express) line on day 1 and day 9, while using the JR Pass for days 2 to 8. Would this be a better/cheaper option than the one you suggested?
Basically my question would be, the Suica has a value of 1,500 right - would this be enough for a day's travelling around Tokyo.. say visiting some 3-4 attractions? (Not disneyland of cause)
