PLEASE READ: This location is difficult to find by relying on GoogleMaps or similar alone. I appreciate the locals that helped us because we were wandering for a little.
The store is located in Building 2 on level B2, which is two floors down from the ground level. The wayfinding signs indicate which building you’re in with four different colored rectangles in an L-shape and you’ll know you’re in Building 2 when the red box shows a “2”. From the center of the building, you can go in four directions that are marked with kanji. My guess is that they indicate East, West, North and South but I can’t read kanji. You should look for the side with the stairs (opposite the escalators), go past the stairs, and look for a corridor full of shops. Luckily you won’t have to look/walk too far down from that point. Thankfully other reviewers left photos for the lit blue “Ticket Zone” sign that helped us find it.
While this location was hard to find, the employees made the experience a breeze and they were very friendly. It’s recommended to book online as they’ll ask for a QR code to drop off/pick up and you can pay with your card. There is an option to fill out paperwork but it seems you have to pay with cash with this option.
The bonus to this location is that the same level connects to train stations so that made it easy for us to go exploring for the day and come back to get our bags before traveling to our next destination.
