Hi
Me & my family (my wife & my 2 kids age 6yrs & 1yr) are planning to go to Japan from 1st Dec till 10 Dec 2015.
We plan to stay in Tokyo from 1st Dec till 8th Dec, thereafter we plan to to Nagano/Yudanaka to experience snow & see the snow monkey.
We understand that the JR Kanto Pass only cover Shinkansen till Saku-Daira.
Is it possible for us to use JR Kanto Pass to go to Nagano station and pay the difference?
Likewise from Nagano to Tokyo then to Narita Airport using the Narita Express by using the JR Kanto Pass also and pay the difference?
Thanks.
