I'll be going to Tokyo to Kyoto just for a day trip there (round trip).
Could I use the JR Rail Pass for it? My AirBnB host told me to check if they allow it ( round trip for Shinkansen). I'll be staying in Japan for 5 nights and considering buying the 7-Day pass.
But if you add a bit more, like using the Narita Express just once, you'd at least break even.
A better deal would be the japanican ticket.
It's cheaper and faster - you can take the Nozomi bullet train with it, getting you there 30 minutes faster.
As I mentioned, Kyoto deserves a lot more time. If you could add at least one more day, it would be well worth it.
I figure, the JR Rail Pass (7-day) can be used for all of those, right?
If you took a day trip to somewhere like Nikko, Izu, Karuizawa, Kusatsu, or even Sendai, you would at least get some decent savings. Otherwise, why get the pass at all if you lose close to $30?
