Hihokan (熱海秘宝館) (“House of Hidden Treasures”) were only widely scattered across Japan but this sex museum in Atami is the only one remaining today. It sits atop Mount Hachiman and is only open to visitors who are 18 years or older. There are a variety of amusing displays that are fun to explore, including some that offer an insight into the erotic art and sex culture of Edo-period Japan. It’s worth a visit due to its uniqueness and there’s always something to chuckle about with friends.
