Nigi Onsen

【A timeless spiritual spring hidden in the valley】 Encounter the healing sanctuary that has persisted since ancient times at "Nigi Onsen".

Further into the depths of Tenei Village, nestled in the rich embrace of Mount Nigi, lies "Nigi Onsen." Believed to have been opened during the Heian period, this spring has continued to flow for over twelve hundred years without ever drying up, embodying the very life force of the earth. In a deep forest where the noise of civilization cannot reach, the only sounds are the babbling of the river and the calls of birds, making this place truly deserving of the title "the ultimate hidden retreat" left in modern times, filled with tranquility.

■ Connecting with the earth, the mysterious "natural spring"

The essence of Nigi Onsen lies in its "naturally flowing" water that springs directly from the ground beneath your feet.

• Experience the living water: Freshly bubbling hot spring water emerging from between the rocks. If you immerse yourself in the pure water before it touches the air, you will feel the earth's heat permeate your body, slowly melting away the stagnation of your mind and spirit.
• Refreshing your senses in the open-air stream: An open-air bath that allows you to become one with the clear waters of the Nigi River flowing before you. Bathing while gazing at the changing beauty of the valley through the seasons—snowy landscapes, fresh greenery, and autumn leaves—is an irreplaceable luxury.

■ The pride of hidden hot springs gently enveloping travelers

In this area, where accommodations recognized by the "Japan Association of Hidden Hot Springs" are scattered, sincere hospitality devoid of extravagant decorations thrives.

• Enjoying the tranquility: At night, a sky full of stars pours down, and when you extinguish the lights, the boundary between darkness and the warmth of the water disappears.

Throughout its long history, many samurai and literati have healed their wounds and rejuvenated their spirits in this renowned hot spring. Would you like to experience the "true rest" of becoming one with the earth, nestled against the ancient rock face that marks the passage of time?
