Introduction and What to Expect

Imagine wandering through a serene, moss-covered forest that whispers stories of volcanic activity and ancient trees. That’s the Aokigahara Forest, also called the Sea of Trees, which extends roughly 30 square kilometers around the base of Mt. Fuji. This tour offers an inviting peek into this mysterious forest, enhanced by the stories and knowledge of guides who truly love sharing their insights.

The highlight for many is the visit to the Mt. Fuji Ice Cave, an extraordinary lava cave where ice persists throughout the year. It’s not every day you can walk into a cave and see ice formations in the middle of summer or winter, thanks to the volcanic activity that created it. The tour, typically lasting about three hours, combines walking, cave exploration, and learning, making it a thoughtfully paced adventure suitable for families, couples, groups, or solo explorers.

One of the most praised aspects of this experience is the guides’ expertise. Many reviews mention how guides make the trek engaging and fun, with stories, humor, and clear explanations about the natural environment. For instance, guests describe their guides as “extremely knowledgeable,” “very friendly,” and “hilarious,” which goes a long way toward creating memorable moments.

The Itinerary: What’s Included?

Stop 1: Aokigahara Forest

Your journey begins at the Roadside Station Narusawa, a convenient meeting point near Kawaguchiko Station. From there, you’ll hop into a shuttle and head to the forest—a quiet, lush expanse that feels worlds away from Japan’s bustling cities. As you start hiking, you’ll be captivated by the unique shapes of the trees and the plateau lava flows that characterize this volcanic landscape.

One of the standout features is the moss, which blankets much of the ground in the forest, adding to its surreal, almost otherworldly atmosphere. The guide will point out various flora, including rare orchids, mushrooms, lichens, and algae, depending on the season. Visitors often mention spotting Japanese squirrels and deer, and hearing the melodic calls of woodpeckers and other birds.

While walking, you’ll learn about Japanese legends surrounding the forest—such as the infamous Aokigahara’s reputation—but the guides focus on the natural beauty and ecological significance of the area. The forest’s size, about 30 square kilometers, is comparable to the Tokyo Dome, giving you a sense of its vastness and diversity.
