Is it worth to buy a 7 or 14 days jrpass?

Hello there,

I checked your itinerary for the best option and would advise buying normal tickets your planned trip.

The JR Pass works great when used to travel a couple of times on the Shinkansen. In your itinerary this is limited to a one way Tokyo/Hakone - Kyoto. The JR Pass would have been a great option if you made a return Tokyo - Osaka.

I Hope this helps,
Daniel
