3 weeks schedule

Hi there!

We will visit Japan from the 16th of March until the 5th of April. We have the following schedule and we were wondering if we could have any advice on whether or not buying a (regional) JR pass:
Narita airport arrival on the 16th of March - Tokyo - Magome - walk to Tsumago - Tsumago - Kyoto (incl. daytrips to Nara and Osaka) - Hiroshima - Kumamoto (incl. a daytrip to mt. Aso) - Okinawa (by plane from Kumamoto) - Tokyo (by plane from Okinawa on the 4th of April) - Leaving from Tokyo Narita airport on the 5th of April.

We would appreciate the advice on what kind of pass to buy for our trip!
