Travel Tokyo to Ainokura with a JRP?

What's the best way to travel from Tokyo to Ainokura with a JRP?Thanks for any help! Thomas

Take the Hokuriku Shinkansen from Tokyo to Shin-Takaoka (covered by the JRP), then the JR Johana Line to Johana (covered by the JRP) and then the bus to Ainokura (not covered):

Those who prefer comfort over money, transfer to the non-JR bus at Shin-Takaoka instead of Johana. It is more expensive but is easier.

Thank you very much. That's how we'll do it! :)
