Atami Castle may look ancient, but it's actually a modern creation from 1959, built purely for fun and tourism. Standing tall at 120 meters above sea level, this castle offers panoramic views of Sagami Bay that will take your breath away. While you're there, you can dress up as a samurai, check out some cool ukiyo-e art, and learn about other castles in Japan. And don't miss the cherry blossoms in spring or the Atami Marine Fireworks in summer – they're a sight to behold!
