Two Travelling in May 2026

Wondering if it's better to get JRPasses or buy individual fares or combination of both. Happy to pay a little more for convenience. Our itinerary for two adults is:

May 13: Narita International Airport to Shinjuku Station, Tokyo
May 17: travel to Fujiyoshida, Yamanashi
May 19: travel to Higashiyama Ward, Kyoto
May 25: travel to Higashi Ward, Hiroshima
May 26: travel to Miyajima Island
May 28: travel to Kanazawa
May 31: travel to Narita, Chiba
June 1: travel to Narita International Airport

Any suggestions appreciated!
