Tokyo - Kyoto - Hakone 7 or 14 day JR pass

Hi there,

We are trying to decide which/if JR rail pass to purchase for our upcoming trip to Japan: none, 7-day or 14-day.

We land in Tokyo HND on March 30,
Travel to Kyoto on April 4
Travel to Hakone April 9
Leave via HND April 10

We are not sure what other travel we will be doing while in Japan, but may take day trips from either Tokyo or Kyoto.

Thanks in advance,
Bret
