3 weeks stay and 14 days JR Pass

Hi, we arrive Tokyo-Narita on 18/03/2025 and our itinerary is planed as follows

18/3 - 22/3 TOKYO
23/3 TOKYO - NAGANO
24/3 NAGANO - KANAZAWA
25/3 KANAZAWA - KYOTO
25/3 - 28/3 KYOTO
28/3 KYOTO - OSAKA
28/3 - 31/3 OSAKA
31/3 OSAKA - HIROSHIMA
31/3 - 2/4 HIROSHIMA
2/4 HIROSHIMA - KAGOSHIMA
3/4 KAGOSHIMA - NAGOYA
4/4 NAGOYA - ŠIZUOKA
5/4 ŠIZUOKA - TOKYO
5/4 - 8/4 TOKYO
8/4 departure TOKYO - NARITA

I suppose 14 days JRPass dated from 23/3 to 5/4 could be very good solution.
Could you please confirm or any comments or recommendation??
Many thanks in advance
