It was a happy coincidence last year when I visited Tokyo I met Mr. Narita who was the contractor to build both the Traveler's Factory Nakameguro store and the Narita Airport store. I was blessed to see some of the sketches at times before the stores were built.
Courtesy from Mr. Narita on his Flickr site, you can see "the making of " photos from the former paper factory situated in Nakameguro Tokyo to the current Traveler's Factory principle store. From stories I heard, it was built with a lot of hearts from choosing the site, material specification and sourcing, sign painting to the product selection. It is definitely one of the classic stores in our lifetime.
