Atami Castle is a spectacular replica fortress constructed in 1959 (Showa 34) and built solely for tourism rather than historical military use. Located approximately 160 meters above sea level, it commands an exceptional vantage point overlooking Atami City, Sagami Bay, and the surrounding coastline. Although modeled after the architectural style of the Momoyama period, the castle integrates modern museum spaces and recreational facilities, offering a uniquely broad visitor experience.

The 6th-floor observation deck is the star attraction, providing 360-degree panoramic views. From this height_, visitors can admire not only Atami City but also Yugawara, Shinsuru Peninsula, Hatsushima, and Izu Oshima. On clear days, the vista extends astonishingly far—enough to see Tokyo Skytree and Yokohama Landmark Tower in the distance. The deck offers numerous designated photo spots, ideal for capturing breathtaking coastal landscapes.

Inside the castle, each floor features specialized exhibitions and activities:

• 6th Floor – Panoramic Observation Tower
  The most scenic location in the castle, offering wide-angle views of the ocean, city, mountains, and distant metropolitan landmarks.

• 5th Floor – Touch & Try Edo Corner
  An interactive cultural zone where visitors can wear Edo-period costumes—such as feudal lords, samurai, or princess attire—for unique photo sessions. This immersive floor recreates elements of Edo-era life.

• 4th Floor – World of Rebus
  A charming exhibition themed around Japanese rebus puzzles and wordplay, showcasing traditional visual riddles and clever artistic concepts.

• 3rd Floor – Ukiyo-e Erotic Art (Shunga) Exhibition
  An adults-only gallery featuring erotic ukiyo-e masterpieces by renowned artists including Kuniyoshi Utagawa. This rare exhibit presents historical interpretations of Shunga culture.

• 2nd Floor – Japanese Castle Museum
  A detailed display of models and reconstructions of Japan’s most famous castles. Some pieces are intricate matchstick models, offering insight into architectural diversity across regions and eras.

• 1st Floor – Samurai Culture Museum
  Exhibits include genuine samurai armor, folding screens, matchlock guns, and real Japanese swords. Visitors can hold an actual katana to feel its authentic weight—an uncommon hands-on opportunity. Free massage chairs are also provided for relaxation.

Beyond the interior exhibits, Atami Castle includes a variety of complimentary and family-friendly facilities. The open-air foot bath terrace lets guests enjoy warm water and ocean views simultaneously.
The basement is a large amusement area featuring:

• Free arcade games
