[Kanagawa] Sarushima 1.5-Hour Private Island Exploration

Join a 1.5-hour guided tour of Sarushima, Japan’s only natural island in Tokyo Bay. Take a short ferry ride from Yokosuka and explore this uninhabited island, often nicknamed “Japan’s Laputa” for its moss-covered ruins, red-brick tunnels, and overgrown stone paths. Once a military fortress protecting Tokyo Bay, Sarushima still preserves traces of gun batteries, hidden chambers, and defensive structures from the Edo to Meiji periods. As you walk with your guide, learn how the island changed from a coastal defense site into a quiet place where history and nature blend together. Enjoy ocean views, atmospheric ruins, and unique photo spots on this short but memorable island adventure.
