Switching between trains covered and not covered by JR Pass

Hi,

We are going to Nagoya this March and we will use Takayama-Hokuriku Area Pass. We are just wondering how will we go about switching trains that covers JR and non JR Line.

For example, we will go to Takayama from Chubu. Per Navitime, we will board Meitetsu Tokoname Airport Line from Chubu to Kanayama Station (not covered by JR Pass), then transfer to JR Tokaido Mainline from Kanaya Station to Nagoya Staition (not covered by JR Pass). From Nagoya Station we will boad Hida Line going to Takayama (covered by JR Pass).

Do we need to exit Nagoya Station thru some fare gate first before riding Hida Line to Takayama since the first 2 train rides are not covered by JR Pass or can we just stay at the platform? Per Navitime, we only have 5 min between alighting the train from Kanayama and boarding the train to Takayama.

Thank you for your help.
