Yokosuka: Guided Island Tour to Sarushima’s Forgotten Fort, Kanagawa Prefecture

This is not just a day trip—it’s a step into another world.

Our Sarushima tour combines history, mystery, and nature in a way few places in Japan can. You’ll board a short ferry ride with your local guide and arrive at Tokyo Bay’s only natural island—an uninhabited former military outpost now overgrown with moss, vines, and silence.

What sets this tour apart is the exclusive guided experience through hidden tunnels, stone ruins, and forgotten artillery platforms—places that most visitors pass by without understanding. Your guide will bring the island’s dramatic story to life, from samurai-era defenses to Meiji-era military secrets.

With no cars, no crowds, and no commercialization, Sarushima offers an untouched atmosphere that feels like a real-life movie set. It’s the perfect escape for travelers seeking something truly off the beaten path—mysterious, beautiful, and deeply connected to Japan’s past.

Short ferry ride. Deep discovery. A journey you won’t forget.
