Should we get 2 week JR Pass?

Hello - we are planning our 2nd trip to Japan as noted below and I am wondering if it is worth getting the 2 week JR Pass for travel with the itinerary below that we activate for travel on 7/11 to Kanazawa and use to get back from Kansai area to Tokyo?

7/6 - 10 Narita to Tokyo (will take a day trip to Nikko)
7/11 - 14 travel from Tokyo to Kanazawa
7/14 - 16 Hakone
7/16 - 20 Kobe/Osaka (maybe day trip to Kyoto)
7/20 - 22 take bus from Osaka to Tokushima to visit family
7/22 - 24 Hiroshima & Miyajima
7/24 -25 maybe one night in Kyoto or Osaka
7/25 - 26 Tokyo then fly out from Narita

OR--Would we be saving more money by getting a 7 day JR Pass that we use for travel to Nikko, Kanazawa, Hakone and one way trip to Kansai area, and then buy regular tickets for the rest of the trip?

We are committed to the 7/20-22 dates to go to Shikoku which cuts into the value we might have gotten from a regional Kansai-Hiroshima pass.

Thank you in advance for any insight you can provide!
