14 day or 21 day pass?

Hi,
We’re going to be in Japan for 19 days. I’m finding it s not difficult to work out what is covered by the pass and what isn’t. Our itinerary is:

Day 1: Narita Airport to Shinjuku station

Day 5: train to Matsumoto and then onwards to Takayama (train and bus: I know bus isn’t covered by JR)

Day 8: Takayama to Kyoto

Days 10 and 11: day trips to Nara and Osaka

Day 13: Kyoto to Koyasan (I know part of this isn’t covered by the JR Pass)

Day 14: Koyasan to Tanabe (ditto)

Day 17: Tanabe to Yokohama

Day 18: Yokohama to Tokyo

Day 19: Tokyo to Narita Airport

Looking at this, I think everything else is covered by the JR. But could you let me know if I’m wrong? Thanks!
