Kamikochi and Takayama

Hi,

Earlier this week I asked about transportation to Kamikochi. You told me that we could take a bus to kamikochi and you gave me the correct website. Thank you for that.
However I still don't understand how we can travel from the kamikochi bus terminal to our hotel/roykan.
All the roykan/hotel that are still available aren't near to the bus terminal or in kamikochi self. They all lie in the neighborhood of the abo-toge road.
But I don't know how we could get there with public transport?
Can we take a train or is there a bus that we can take from Takayama or Matsumoto to get nearby the hotels?

Thanks in advance.

Best regards,
Hylke
