Shoryudo bus pass

Hi. I plan to visit shirakawago and ainokura using the sghiryudo pass. Bases on what i read the trip to shirakawago is covered by the pass. Does it also cover the bus ride to ainokura? And can we get a bus back to nagoya from ainokura that is covered by the pass? Thanks

Does it also cover the bus ride to ainokura?

There are three version of the pass. Among the three versions only the "5 days - Wide Area" version covers the bus to Ainokura. The 3-day versions don't.

Details are explained here:

There is no direct bus from Ainokura to Nagoya. But the one from Shirakawago to Nagoya is covered.

Please confirm that we CANNOT make a reservation online or via call using SHORYUDO bus pass.
We can only make a reservation at the designated counters in certain bus stations.
