Arriving Narita airport Jun 1
Staying in Tokyo till jun 5
Going to Kyoto June 5 till 9
Will visit Osaka for a day on 8th
Coming back from Kyoto to Tokyo Jun 9
Leaving jun 10 via Narita airport
So, I wonder when would be the best date to activate my 7 day JR pass?
Also, wanna double check to see if JR pass covers JR metro line in Tokyo, Kyoto and Osaka?
Thx in advance
