The abandoned Japanese Sex Museum (a.k.a. the Mansion of the Hidden Treasure) first caught my attention in 2009 when I first started doing some research about haikyo on Japanese blogs. Three years ago the museum showed up on two or three homepages; both urbex and more general pop culture blogs. After that it basically disappeared, I haven’t seen pictures of the place ever since. So what happened? Boarded up? Security? Maybe demolition? Since *Michael* and I *were in the area anyways* we decided to find out, especially since the museum was pretty much on top of both of our “Places I Want To Explore” lists.
I guess the abandoned Japanese Sex Museum, along with the *Maya Hotel* and *Nara Dreamland*, was actually one of the locations that convinced me that Japan not only has abandoned places, but that it has some great ones. There are not that many sex museums in the world overall – so an abandoned sex museum is pretty unique! (Although “Abandoned erotic art museum” would be a slightly more correct name for the place now that I know what’s to find there.)
Opened on October 1st 1978 the Mansion of the Hidden Treasure was in business for almost 20 years before it was closed in the second half of 1997. Mansion of the Hidden Treasure is actually a great name since the exterior looks like a massive, old-style Japanese mansion, like a fortress almost. The entrance was guarded by a statue of Daikoku, the God of Great Darkness and one of the Seven Gods of Fortune. Opening hours were from 9 a.m. till 11 p.m. and the entrance fee was 1000 Yen according to a pamphlet that was lying around in an office room. Exploring the place further we found actual tickets with a printed price of 1300 Yen, so I guess the entrance fee was raised at least once during the 19 years of business. Several vending machines near the entrance and the exit offered all kinds of items, for example erotic playing cards and saucy postcards at the price of 300 Yen. One of the trashed rooms had a small stage and nearby we found a sign that said “Nude Show 2500 Yen”, so I guess it’s safe to say that there were live performances at the museum, too.
(If you are easily offended by sexual contents and you nevertheless read this far I strongly recommend to move on to another posting as from now the article will become a little bit more specific – while at no point pornographic I might mention the p-word once in a while and the photos at the end… or dear… well, it’s an abandoned sex museum, of course the exhibits are 99% erotica!)
As you may or may not know pornography in Japan is usually censored due to article 175 of the Criminal Code of Japan which says that people who sell or distribute obscene materials can be punished by fines or imprisonment – meaning that genitalia are usually blacked out, white out or pixelated with mosaic. Article 175 was part of the original Criminal Code passed in 1907 and remains pretty much unchanged till this very day. It was the written manifestation of the Meiji Era efforts to reduce the publication of pornographic materials. Before the second half of the 19th century the shunga, erotic woodblock prints and therefore a type of ukiyo-e, were quite popular – and as explicit as modern western pornography; probably even more imaginative since the shunga not only showed traditional sexual acts, but also sex with animals, demons and deities. Some of them even showed sex with foreigners… And I guess that’s where the worldwide image of weird Japanese porn comes from. Well, that… the used panties vending machines and of course the anime series Urotsukidoji, famous for inventing tentacle rape, creating a whole genre with just one extremely disturbing scene…
With that being said there was no pornography found in the abandoned Japanese Sex Museum – only a couple of paintings (some of them in a special room with black light lamps), softcore photos (e.g. Playboy Centerfolds), a couple of mannequins as well as lots and lots of wooden and stone sculptures; dozens of them, to be accurate. Sculptures of penises, vaginas, combinations of both, couples in the act, buttocks, masturbating animals, priests, deities, demons and whatever you can imagine. In one room there was a forest scene with penis shaped mushrooms. Or mushroom shaped penises. Your guess is as good as mine. It was almost impossible to open your eyes without looking at a phallic symbol.
While two or three rooms were completely trashed (basically the entrance and the exit areas as well as the offices upstairs) some of the exhibition area’s ceiling was quite moldy, but still in good shape. Those huge statues must have been insanely heavy, especially sculptures like the stone penis with a length of almost two meters, and let’s be honest: Who would actually hit a giant stone vajayjay with a sledgehammer or tip over a couple of marble dicks? Even the most ruthless vandal respects those symbols!
Sadly that didn’t apply for the female models. The main exhibits in the last room were stolen (or “taken to security” by some previous explorers…) a year or two ago. One was a wax model of the famous European softcore erotic character Emmanuelle, the other one was a replica of Marilyn Monroe – both presented in slinky poses behind now broken glass. The already mentioned pamphlet / flyer featured photos of both wax figures and they looked pretty amazing. Even more so on the already mentioned Japanese blogs I saw a couple of years ago. When the museum was still open to the public the wax figures were scantily dressed and well-lit behind glass, but once it was abandoned the new visitors had less respect and undressed both Marilyn and Emmanuelle to show lower body parts that were out of sight before – and surprisingly both models were not as anatomically impaired as a Ken doll.
The left behind mannequins on the other hand were exactly that: Rather gender neutral below that waist and more or less what you can see at every clothing store when the clerks redress the shop window dummies. Of course they were all (partly) dismembered and slightly damaged, but they were basically normal mannequins… except for the really disturbing “Sleeping Beauty” one, which had vibrators mutating out of her nipples.
The main challenge from a photography point of view was the fact that 80% of the museum was pitch black, which meant that I had to take every shot with a tripod and illuminate every photo individually with my flashlight; similar to what I did at the *Lost Subterranean Shrine*.
With a sheer endless amount of statues and the time consuming process of taking photos Michael and I spent a whopping four hours at this fascinating location. Like I mentioned at the beginning, we both had high expectations about the abandoned Japanese Sex Museum and they were not only met, but exceeded. This haikyo is without the shadow of a doubt one of the best abandoned places in Japan and it would be a place worth visiting anywhere in the world. I just hope that future visitors will treat the location with the same respect Michael and I did so it will put a smile on the faces of urban explorers for decades to come…
