I make it a point to visit the Nakano location every time I'm in Tokyo, but was surprised to learn that the store had moved from the cloistered, nerd enclave of Nakano Broadway, to the more hip Harajuku neighborhood. The new space is about the same size, but is much easier to locate, as it's right at street level.
And, as seen in the photo above, they even got a rebrand! I'd heard that this was happening to select locations in the UK, but hadn't seen one myself.
They also maintain an active presence on Facebook, and the shopkeeper posts in both English and Japanese.
