Video: “HIHOUKAN (House of Hidden Treasures)” erotic museum at Beppu, Oita Japan (museum now closed, sadly).
The above video is from this io9 post – Japanese sex museums are where your sanity goes to die (NSFW). The post’s photos are poorly attributed and the text is meh but the gallery and links are excellent.
