Hokkaido in July

Hi,

I would like to check if a 3day JR pass would suffice or would i even need a JR pass taking into account my itinerary appended below. Please note that we would also be doing a driving tour in some parts of our travels.

Grateful if you could kindly advise.

Thanking you in advance.
