14 or 21 day pass

Hello!

Traveling in November with a 3 week itinerary. Trying to determine if I need the 14 or 21 day pass.

Nov 4 - 10 - Tokyo (landing in Haneda, staying in Shinjuku
Nov 10-14 - Kyoto
Nov 14 - 17 - Osaka
Nov 17 - 19 Fukuoka
Nov 19-22 - Hiroshima
Nov 22 - back to Haneda to leave.

I believe I will def need/have value if I did the 14 day pass from 11/9 - 11/22 when I depart Tokyo to journey south.

My question - would there be value if I got the 21 day pass for my time in Tokyo considering the below:

11/4 - travel from Haneda to Shinjuku on Limo bus
11/5 - explore shibuya, asakusa, harijuku (possible group bus tour)
11/6 - day trip to Disney Sea
11/7 day trip to Hakone
11/8 day trip to Kamakura
11/9 relax in area around hotel

Would the JR pass be of any value in the above itinerary or would I be better to get an IC card and load it for the subways and individual trains? I would be getting an IC card anyway, to be clear for subway travel. Just didn't know if the JR pass would save me time/money especially for those day trips to Disney, Hakone and Kamakura.
