Confirming Trains & JR Access

Hi Friends, I am routing myself through Japan, using Google Maps. I would like to take a day trip from Toyko and visit a few spots along the way all via train & bus. Itinerary includes.

Shinjuku Station - Kamakura Station via Shonan-Shinjuku Line (JS20)

Kamakura Station - Odawara Station (It looks like I am on JR trains (Yokosuka Line & Odoriko) but once in Odawara I will then take buses to get to Hakone Shrine. How do I know if this bus accepts JR Passes (here is the Google Link to the route - https://goo.gl/maps/6XFjDTf59q72).
