Atami Adult Museum.

The Atami Adult Museum, or Atami Hihokan, is an unconventional attraction perched atop a cliff, offering breathtaking coastal views and a playful experience that blends humor with Japanese eroticism. This retro-themed museum, reminiscent of the 80s, features kitsch elegance and a variety of quirky, interactive exhibits, such as twisting handles and playful water surprises. Visitors can explore historical artifacts like traditional *shunga* art, Edo-era silk condoms, and antique sex toys, all set against a backdrop of traditional Japanese music. As the last remaining adult museum from Japan's Showa era, it delivers a nostalgic and entertaining journey through Japan's erotic history, making it a unique spot for those looking for a memorable and lighthearted experience.
