Info nakasendo way

I'm planning a trip to Japan with an itinerary from Tokyo to Kyoto from July 2nd to July 21st.
I need information on a part of the itinerary:
Arrival in Kanazawa from Tokyo via Shinkansen (all clear).
My difficulty is in understanding which transport to take to do this itinerary
09 July: departure in the morning from Kanazawa to arrive at Shirakawa-go and then in the afternoon departure towards Takayama, overnight stay in Takayama
July 10: visit the city of Takayama, overnight stay in Takayama
July 11: departure from Takayama and arrival in Magome to travel the 8 km of the Nakasendo route from Magome to Tsumago, with an overnight stay in Tsumago
July 12: departure from Tsumago towards Osaka, overnight stay in Osaka

Can you give me information on which buses or trains I should take and the times? Thanks a lot!
