What is the best ROUND TRIP Rail Pass from Narita Airport to Tokyo, Tokyo to Mt Fuji and Tokyo to Osaka?

Hello there,

I would recommend using a 7 day JR Pass for your trip. There's not really any other pass that matches your itinerary. The cost of a 7 day JR Pass is about the same as a normal RT ticket between Tokyo - Osaka using the Shinkansen. Now you get 7 days of unlimited travel for the same price.

1.) Yes, the JR Pass covers all these routes with one note on Fuji, it will depend where around Fuji you will visit. For details see this page.

2.) Yes, the local JR network in both Tokyo and Osaka is covered.

3.) You can find pricing for the JR Pass here: https://www.jrpass.com/buy_the_japan_rail_pass_online

Kind regards,
