Hi, i've been reading information on JR Pass but i'm still confused.
I and my nieces will be travelling to japan in Apr'18. We will be arriving @ KIX and will go to our rented house at osaka.
We have yet to come out with a detail itinerary but planned to travel/walk around Osaka, Kyoto, Nara and maybe Kobe.
Do we need to buy JR pass? Or can we use the Icoca card for our 7 days at these areas?
Kindly advise, thank you :)
