What pass to get?

Hi, what pass can I get if I want to travel to tokyo, Osaka, Kyoto and Mount Fuji within a period of 10 days.

If its a round trip then the 7 day JR pass will pay off. Otherwise, its probably cheaper to do by regular tickets.

Thanks for the reply. Does the JR pass allow me to go to mt Fuji? Will it be better to travel to tokyo- Osaka- Kyoto- mt-Fuji then back to tokyo ? If use the 7 day pass, which day sld I start to use? How abt the remaining 3 days? If first 3 days at tokyo then buy another pass?

Most of the way, but you'll have to take the non-covered Fujikyu line between Otsuki and Kawaguchiko, and then a but to the mountain.

Sure, that would be ok. Note then that there is a 1 hour bus is involved. See this page for more info:

Day 4 or the day you leave Tokyo, whichever comes first.

If first 3 days at tokyo then buy another pass?

Maybe looking into the oneway Suica+NEX package to get you from the airport to Tokyo and then use the suica to pay for single train trips around the city:

How about travelling within Osaka and Kyoto? Does the jR pass allow me to travel around and go to universal studio?

How much does the suica nex card cost?

Yes its good to USJ. In Osaka and Kyoto its only valid on JR lines (which is not so helpful in Kyoto).

How much does the suica nex card cost?

3500 yen (all the info is on the page I linked).
