To get to GranDuo Kamata, you should be able to see the entrance to the GranDuo building from near the ticket gates of JR Kamata Station.
There are two GranDuos, one on the west side and one on the east side, and you can move between the east and west sides via a connecting passage.
You can access the east-west connecting passage from the 3rd floor, and there is a resting area where you can sit by the window.
There are seven 3-seater benches.
Round cushions are placed on the benches, so they are quite comfortable.
Because there is plenty of space in the passage, you can relax without feeling cramped, even though it's near the station.
You can look down on the central ticket gates from the window in front, so it's perfect for meeting someone in Kamata!
(Except for cafes, there are not many resting places where you can observe people near the ticket gates.)
This east-west connecting passage with a resting area is also easy to find, so it's generally convenient, considering the access from the station.
Why not use it as a resting place with seating in the Kamata area when you are shopping at GranDuo Kamata?
