First, go out from the east exit of Motomachi Station and cross the traffic lights to the south.
Once you find this sign, please take this narrower path.
Walk about 150m and when you see Evian Coffee, take the elevator on the left and press 5.
Go down to the 5th floor and there is a cafe sign in front of room 501 on the far left, so enter and go further back.
