NAgoya -TAkayama- NAgoya

JAn16 2020 NAgoya
17 NAgoya
18 NAgoya to takayama
19 Takayama to Shirakawa go to TAkayama
20 Takayama to KAnazawa to Kagaonsen to KAnazawa
21 KAnazawa
22 KAnazawa to NAgoya

Will the 5 day Takayama-Hokuriku Tour PAss cover also the bus from TAkayama Train Staion to Shirakawago at night and then back to my hotel in HidaTakayama again? Do i have to reserve early for the SHirakawa bus ? online possible?

Any input on this will be much appreciated. The Shirakawago illumination is the hilite of my trip..
