Travelling from Nozawa Onsen to Osaka

Hi there,

Take the bus to IIyama, then the Shinkansen to Kanazawa and finally the Thunderbird express to Osaka.

Hope this helps,
Daniel

Thanks a lot Daniel-san

Sorry another question, is there anyway I can activate my JR Pass at IIyama?

Not at Iiyama I'm afraid, a full list of stations can be found here:
