11 Days in Japan (do I need JR pass)?

hello there, I'm hoping you could help me to decide if I need to buy 7 days JR pass for my itinerary below

21/10/17 - Tokyo
22/10/17 - Tokyo
23/10/17 - Yokohama
24/10/17 - Tokyo (Disneyland)
25/10/17 - Hakone
26/10/17 - Kanazawa
27/10/17 - Shirakawa-go
28/10/17 - Nagoya
29/10/17 - Kyoto
30/10/17 - Nara
31/10/17 - Osaka
1/11/17 - Osaka International Airport

I was thinking to activate my 7 days JR pass from 26/10-1/11, Do you think is it worth to buy 7 days pass? also any suggestions any area in between to visit when use my 7 days JR pass? or do I only need to buy the ordinary ticket?

Thanking you in advance,
Januar
