If you’re craving a break from the crowds and commercialized tourist spots, this guided tour to Sarushima, Japan’s only natural island in Tokyo Bay, might just be what you need. For around $126, you’ll spend about 90 minutes exploring a place where history, nature, and mystery collide. Led by a knowledgeable local guide, you’ll board a short ferry ride from Mikasa Pier in Yokosuka and set out on an adventure that’s as much about discovery as it is about escaping into serene, untouched landscapes.

What truly makes this tour stand out is the chance to step into a hidden world of moss-covered ruins, tunnels, and artillery platforms that most visitors simply pass by without understanding.

The island’s status as uninhabited since its military days means no cars, no modern buildings, just nature and ruins. Your guide, possibly someone like the reviewer Valentina, brings the island’s past alive with stories—from samurai defenses to Meiji-era military secrets—making the history tangible.

As you walk along forested trails, you’ll see moss-covered stone walls, red-brick tunnels, and remnants of artillery platforms.
