SexMuseums.com Naughty Places to See

While Japan doesn’t have a single, widely recognized “Grand Japanese Sex Museum” like in some Western cities, it does have a scattered collection of unique, erotic-themed exhibition spaces, often referred to as hihōkan (treasure houses) or museums combining sexual education and culture.

The most notable operating ones include:

1. Atami Adult Museum (Atami Hihōkan)
   • Location: Atami, Shizuoka Prefecture.
   • Description: This is often cited as the last of the Showa-era (1926-1989) sex museums still operating in Japan. It features humorous, quirky, and sometimes elaborate displays, along with historical artifacts like shunga (traditional Japanese erotic art) and sex toys from the Edo period. It’s known for focusing on “humor and nonsense.”
2. Taga Fertility Shrine & Sex Museum
   • Location: Uwajima, Ehime Prefecture (Shikoku).
   • Description: Located next to a fertility shrine, the museum is known for its intense and visually overwhelming collection of international and Japanese sexual artworks, photographs, and paraphernalia. The shrine itself features large phallic carvings.
3. Life & Sex Museum
   • Location: Yoshioka, Kitagunma-gun, Gunma Prefecture.
   • Description: This institution combines explicit and humorous sexual exhibits with a serious educational focus on topics like safe childbirth, STDs (including AIDS), and contraception. The ground floor is reportedly open to elementary school children for the educational content, while the second floor is for adults (over 18s).

Note: Historically, there were over 40 hihōkan across Japan, but most were closed in the Heisei era (post-1989). A number of the other places referred to as “sex museums” in search results, such as the Kinugawa Robot Sex Museum and the Mansion of the Hidden Treasure in Kansai, have since closed down.
