My suggestion would be to get two passes and a package. a Takayama-Hokuriku Tourist Pass, and a 7 day JR Pass, and the ICOCA and Haruka one way package.

Use the Haruka to get to either Osaka or Kyoto, and then use the IC card to get around. If you are going many places in one day, then look into a local Kyoto or Osaka pass of some sort, but mainly, just pay as you go with the ICOCA IC card.

Use the T-H Pass to get you to Shirakawa-Go, Kanazawa, and Takayama. It will expire in Takayama.

Activate the 7 day JR Pass to get from Takayama to Hiroshima, and travel around on it until you get to Wakayama. To get to Hiroshima from Takayama, you would take an limited express train to Nagoya, and then a Shinkansen bullet train to Hiroshima. The 7 day pass will expire in Wakayama.

Take the airport bus from Wakayama to the airport. It departs from the west side of Wakayama station.

In terms of your order, you may switch Kanazawa and Shirakawa-go, because the T-H pass will have you going through Kanazawa in order to get to Shirakawa-go. You will be backtracking to go back to Kanazawa.

I hope this helps.

Thank you very much for your reply and advice. however I am leaving in 2 days time and may not ge able to purchase the pass in time since it's sold only outside japan?

Would it be cheaper by bus since I have a lot if time.

Also can I buy. Kansai pass for the Hiroshima to Wakayama sector. In which case is there a bus from Takayama to Hiroshima
