“House NA”, Tokyo’s hide-and-go-see-through glass house (House NA 住所)

December, 2016 update: House NA is now listed on Google Maps. It is located in the Koenji neighborhood of Tokyo, southwest of JR Koenji Station (map).

The first rule of a glass house is you don’t throw stones. Apparently the second rule is you don’t talk about glass houses. At least you don’t disclose the location.

House NA, the intriguing 914 square-foot glass house designed by Sou Fujimoto Architects 藤本壮介建築設計事務所 has been documented generously in words and pictures; the visual record of this young structure is impressive. Surprisingly, disclosure of the house’s specific location is nearly non-existent. Having never backed down from an internet search challenge, I located the building’s exact address using two clues.

First, the house’s location was described by one writer:.

“located on a small side street in a very lively, “hip” part of the city. Full of eccentric, off-the-wall little shops, this neighbourhood’s intense social life is associated with a human-scale ambience made of low houses and mostly pedestrian and bicycle traffic.” Source: domusweb.it

Second, the building’s site plan, combined with knowledge of Tokyo’s geography, provides just enough clues to locate this hidden, or hiding, gem. “House NA” site plan (source):


The location is so well hidden that even a google search including the name of the neighborhood yields few results. (I found success with a Brazilian blog and a thread from a social networking site). The censorious absence of the project’s location is curious. Is there a rule or convention in architectural journalism prohibiting the disclosure of a house’s location?

(Suspiciously, Streetview images from the 20 meters of road fronting the property are not viewable on Google maps, while neighbors on both sides are available.)

So where is this mystery property? In the age of instant Google searches, I feel somewhat protective of the house’s almost-secret location. I may tell you, but you’ll have to ask politely.

  1. Hola! gracias a tus pistas pude encontrar la casa, asique en diciembre iré a verla! Es agradable que exista tal privacidad por los blogs, páginas de turismo o los mismos amantes de la arquitectura para no dar la ubicación exacta, creo que así existe un filtro de personas que realmente están interesadas en conocerla y respetan la privacidad, gracias!

  2. Hi there Clark, I am an architecture student from Australia travelling to Japan in a month, I am hugely fascinated by Sou fujimoto, and many other japanese architects (Tadao Ando and Toyo Ito), and architecture. I would love to visit House NA, as well as House H while I am in Tokyo. Would you please be able to share their locations with me, either the addresses or coordinates? It would mean so much to me and I look forward to hearing back from you. Please feel free to email me back

    Thank you so much for the content, all the best,

  3. Hey

    I have talking about this house for over a year and now I am travelling all the way from Argentina to Tokyo and would love to see it!!

  7. Hello, I am going to Tokyo for House NA and House H on May.
    I will really appreciated if you can tell me the address of these two exquisite works.

  8. hi guys, i’m going to tokyo for nye, i’m a parisian architect and i woudl love to see house na and house h, could you give me your tips through email ?

    • Thanks for the comment. I wish you the best of luck on your search. I think house NA is moderately easy to find, if you use follow the info in this post. House H is a bit more difficult, but I’ve stopped giving additional tips, as I know that Japanese privacy laws are pretty strict, so I’m going to play it safe and just provide the information in the posts.

  9. Yes, thank-you for the “hip” tip also, I found it! Love the lightness of the structure, but, as a parent, concerned about safety – railings, etc. Don’t think this would pass Canadian Building Codes.

  10. Hi, just found your post. I’ve had the same problem as everyone, I will visit Tokyo in a few weeks (my first time) and wanted to see this house. Luckily, after a few google searches and using GMaps and the plan… I found it!
    Thank you for the “hip” tip 😉

    • Hi, thanks for the comment. What have you tried so far? Many people are able to locate it based on the clues in this post. I can’t give you the address but I can let you know if you’re on the right track.
