Would any JR Pass make sense?

Hi,

We are planning our upcoming June trip to Japan and were wondering whether getting some type of the JR Pass would make sense?


Here is the itinerary:

Day 1 & 2- Tokyo
Day 3 - Day trip to Nikko
Day 4 - Tokyo
Day 5 - Overnight stay at Kinosaki Onsen
Day 6 - Kyoto
Day 7 - Day trip to Arashiyama and Sagano
Day 8, 9 & 10 - Kyoto area
Day 11 - Overnight stay at Mt. Koya

Day 12 - Osaka

Day 13 - Day Trip to Nara

Day 14 - Flight from Osaka to Okinawa
Day 16 - Flight from Okinawa to Tokyo Narita
Day 17 & 18 - Tokyo

My friend leaves on Day 18 and I then plan to travel either to Hokkaido or Toyama for 4 more days, but I haven’t planned that part yet.

Any suggestions would be greatly appreciated! :))
