PLAN

Did you know that truly untouched, non-commercial hot springs still exist in Japan?

Deep in the mountains of Kirishima, hidden wild hot springs—known as noyu—are quietly tucked away in the forest. Some sit beside gently flowing rivers, others bubble up from the earth beneath the trees. These are places far from crowds and tour routes, where nature remains unchanged.

On this guided experience, a local expert leads you to one of these remote hot springs—places that are difficult to find without local knowledge.

A noyu is a hot spring left in its natural state. Sometimes it’s nothing more than a small pool formed by rocks, simple and unmarked. And yet, it offers something rare—an experience no built bath or luxury ryokan can replicate.

As you soak, you’re surrounded by the quiet sounds of nature: birds in the trees, wind moving through the forest, and the steady flow of mountain water nearby. It’s a moment to slow down and fully take in your surroundings.

This way of bathing reflects the tradition of toji—a long-standing Japanese practice of restorative hot spring bathing, rooted in simplicity and time spent in nature.

Who this experience is for:

This experience is ideal for those who want to step away from typical sightseeing and discover a quieter, more natural side of Japan.
• Travelers looking for something beyond the usual tourist routes
• Those curious about traditional hot spring culture
• Nature lovers and outdoor explorers
• Guests seeking a more personal and off-the-beaten-path experience

Reaching these wild hot springs may involve walking along uneven or rugged paths. Your guide will lead the way and adjust the pace as needed, making the experience accessible even for first-time visitors with a sense of adventure.

Swimsuits are provided

These natural hot springs are well-loved by locals and occasionally shared. While swimsuits are provided for your comfort, you may encounter others bathing in a traditional style.
