called "Hihokan" which translates to "House of Hidden Treasures"
typically located near Japan's many onsen (hot spring resorts)
boasts both the longest history of sex museums and perhaps the greatest number of them
Privately owned and operated, the variety and type of exhibits
depend on the predilections of the owner
outstanding feature of Hihokan is their vast collections of dildos and other artificial phalli
one particularly noticeable example at the Beppu hihokan standing nine feet tall
a slide down the rod ride to perk you up in a hurry
selection of carnival-style games - each with a unique, sexy twist
variation in mammalian members
displayed by one hihokan's preserved phallic promenade
in order from rabbits to whales
local fertility festivals in which giant replica male organs
then rubbed or ridden by women
