Instead, you’ll stroll along quiet forest trails, taking in views of the sea and the remnants of Japan’s military defenses.

Exploring Hidden Tunnels and Ruins

What sets this tour apart is the guided exploration of tunnels, chambers, and artillery platforms. Your guide will lead you through red-brick tunnels and moss-covered stone walls, sharing stories of Sarushima’s past—from its role during the samurai era to its stay as a military outpost during the Meiji period. These sites are often passed by in other visits, but with the guided approach, you get a full narrative that turns static ruins into a vivid story.

Reviewers mention the thrill of discovering hidden chambers and tunnels that are usually inaccessible to casual visitors. One reviewer appreciated having a knowledgeable guide, who “knew much about the area” and brought the military history to life. These secret spaces offer excellent photo opportunities and a tangible sense of history that most travelers miss.

Overgrown Artillery and Coastal Views

The remnants of artillery platforms and defensive stone walls have an almost cinematic quality. They’re overgrown with moss and vines, giving the impression of a forgotten world that’s been left to nature’s mercy. From these vantage points, you’ll enjoy breathtaking views of the sea—a reminder of the strategic importance of Sarushima in Japan’s defense history.
