The museum utilizes traditional mechanical animatronics that predate modern digital displays.
Atami Hihokan is a Showa-era themed adult museum situated atop Mount Hachiman in Atami, Shizuoka. The facility is accessible primarily via the Atami Ropeway, which transports visitors from the coastline to the summit. It features a curated collection of erotic art, mechanical exhibits, and retro displays reflecting Japan’s 1970s and 80s adult entertainment culture. The museum is strictly restricted to visitors aged 18 and over. Perched on a clifftop, the site offers panoramic views of Sagami Bay and the Atami cityscape. The exhibits utilize dioramas and mechanical displays to present historical and cultural perspectives on sexuality.
