Is JR pass needed

You can check prices on Hyperdia.com. For your trip, there is no benefit at all if you use ordinary reserved seats. If you reserve Green seats (roughly first-class), the costs are almost the same. From Narita airport to Tokyo you could take the express train (around $30), and then take a cab to your hotel. A better choice is to see if the Express Bus stops at your hotel. Then it's door to door service for the same $30. The Green fare from Tokyo to Kyoto is around $180, the ordinary fare is less. From Osaka you take a bus to the airport.

Just one change to my note - there is a JR train traveling directly from Osaka to the Kansai airport. It takes a little over an hour and costs around $12.

Hi there!

I would suggest buying normal ticket for your travel. The JR Pass would not be economic for a one way ticket Tokyo - Kyoto even if you include travel to and from both airports!

Enjoy Japan!
