I was wondering if someone who could help me. Myself and two friends are coming to Tokyo this April. We arrive at Haneda Airport at 7-8am and our check in time for our apartment is 2-3pm. Since we have quite a bit of time to kill I wanted to store our luggage at Tokyo Station and roam around the area before we go to our apartment.
I want to use the Gransta on the B1 floor at Tokyo station as it has a cloakroom for suitcases. (I think the coin lockers would be too small).
Looking at the Tokyo Station floor maps, I can see the best area is the Marunouchi central exit area, but I can't tell if I need a train ticket to access the Gransta.
We will be arriving via the JR Yamanote line. (Platform 4, I think).
So to access this Gransta cloakroom from the JR Yamanote line platforms, would I need to pass through a ticket barrier first? (As Tokyo station is so big and I have poor sense of direction, I just want to make sure I don't exit a barrier and then realise I have to go back through a barrier to get to Gransta.)
I will then be leaving Tokyo station via the Subway Marunouchi Line. So when I return to the Gransta to collect our suitcases after I've finished sightseeing/shopping in the area, would I need to return through a ticket barrier again? And does this ticket barrier only give access to the JR lines? Or would I still be able to access the Marunouchi Line?
I'm open to suggestions as well. (I.e. Would a Suica Pass be most convenient to tap in and out, although I guess I wouldn't want to keep paying to get in an out of Gransta.)
Basically I'm trying to avoid having to by several train tickets just to drop off and pick up luggage.
Many thanks in advance!
