Overview

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 storey to life, from samurai-era defences to Meiji-era military secrets.

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

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

Activity itinerary

Sarushima

  • 1h 30m
Your journey to Sarushima begins with a short but scenic ferry ride from Mikasa Pier in Yokosuka. As you cross Tokyo Bay, the city slowly fades behind you and a sense of adventure takes over. In just 10 minutes, you’ll arrive at Japan’s only natural island in the bay—a place untouched by modern development and rich in history. Once a vital military outpost, Sarushima is now uninhabited, covered in greenery, and filled with remnants of its past. You’ll walk along quiet forest trails, explore moss-covered stone walls, red-brick tunnels, and artillery remains, and enjoy sweeping views of the sea. The island’s peaceful, overgrown ruins often remind visitors of a Ghibli film scene. With no cars, no residents, and nature slowly reclaiming the land, Sarushima feels like a step back in time. It’s the perfect blend of mystery, beauty, and serenity—just a short boat ride away from the mainland.
