JR Pass or not?

21 day pass or get 14 day pass and pay for local travel between Tokyo and Hakone

Day 1 Narita to Tokyo stay for 3 nights
Day 4 Tokyo back to Narita to pick up my daughter at airport
a) May go back to Tokyo depending on her arrival time
b) go from Tokyo to Hakone
Let say b)
Day 4 Narita to Hakone for 2 night
Day 6Hakone to Tokyo for 2 nights
The above section should l not get a pass

Day 8 Tokyo to Morioka for 3 nights
Day 11 Morioka to Kyoto for 4 night
Day 15 Kyoto to Oasaka for 3 night
Day 18 Osaka to Tokyo for 2 nights
Day 20 Tokyo to Narita depart Japan

Would it be better to buy 21 day pass or buy a 14 day pass that starts at Day 8 and start 14 day pass on day 8

Thank you very much
Pat
