Sarukura Onsen (猿倉温泉)

Sarukura Onsen: The Volcanic Soul and High-Altitude “Beauty Waters” of Mt. Chokai

Nestled on the northern slopes of the majestic Mount Chokai—known as the “Dewa Fuji” for its staggering beauty—Sarukura Onsen (猿倉温泉) is an alpine sanctuary of steam and silence. Located at an elevation where the crisp mountain air meets the heat of the earth’s magma, this hot spring village has served as the definitive “Base Camp” for climbers and explorers for over 300 years.[10] The name “Sarukura” stems from a legend where a hunter discovered the springs after watching Saru (monkeys) bathing to heal their wounds.[10] For the international traveler, Sarukura offers a rare encounter with the “True North”: a place to soak in syrupy “skincare waters” while watching the clouds dance around the volcanic peaks of the Mt. Chokai Global Geopark.

The Healing Waters: Earth’s Natural Serum

The waters of Sarukura are born from the volcanic depths of Mt. Chokai and are characterized by their incredibly high concentration of minerals. Classified as a Sodium-Chloride / Hydrogen Carbonate Spring, the water is colorless but possesses a unique “Toro-toro” (syrupy) texture.[11]

The Skincare Chemistry: The presence of high Metasilicic Acid—a natural moisturizing agent found in high-end skincare—helps promote skin metabolism and moisture retention. The hydrogen carbonate acts like a gentle soap, cleansing the skin while the salt content forms a microscopic “veil” to trap heat. This dual effect earned it the reputation as the “Water of Eternal Youth” among local dwellers.[11, 10] Balneologically, this is one of the most sophisticated springs in Tohoku for physical rejuvenation after high-altitude exertion.

Local Gastronomy: The Kingdom of Yuri Beef

Vegetarian/Vegan Survival:
For Vegans: This area is an agricultural powerhouse. Request the “Mountain Vegetable Stew”—be sure to specify “Katsuo-dashi nuki” (No fish dashi). The local “Ouchi Tofu” is exceptionally dense and rich. We also recommend visiting the BIBI CAFE (approx. 40-min drive) for modern plant-based snacks and acai bowls.

Cultural & Historical Context

The name “Sarukura” combines Saru (monkey) and the Ainu word Kura (cliff/valley), signifying the area’s recognition as a place of natural power long before modern history.[10] Historically, the mountain was a center for Shugendo (mountain asceticism), and the onsen served as a site for ritual purification for pilgrims seeking the blessing of the “Deity of Chokai.” Today, the village preserves its “Slow Life” while providing world-class mineral wellness.

Practical Travel Tips for International Visitors

• Tattoo Policy: Hotel Foresta Chokai is accustomed to international guests and is generally tolerant. While stickers are preferred in communal tubs, small tattoos are common and overlooked.
• Connectivity: Free public Wi-Fi is available in the Foresta Chokai lobby and guest rooms. Mobile signal is stable in the village but can be lost on higher mountain trails.
• Cash & Payments: Major hotels accept credit cards (VISA, JCB, etc.). However, the Yuri Kogen Railway and local village markets are strictly cash-only (JPY).
• Rental Car: A rental car is highly advised to explore the distant waterfalls and trailhead markers. The “Birdie Line” mountain road offers spectacular views but can be winding.

2025-2026 Latest Updates

In August 23-24, 2025, the region will host the “Sea to Summit” event, where participants kayak from the coast, cycle through the foothills, and hike to the Chokai summit. The Mt. Chokai Blue Line road is scheduled to open for the 2025 season on April 25th, allowing for the famous “Snow Wall” driving experience.

Safety & Manners

In the onsen, always sit on the provided stool while washing; do not shower while standing. Because the water makes your skin very smooth, walk slowly on the wet stones of the Rotenburo. Finally, be mindful of wildlife (bears and deer) if driving on the mountain roads at dusk—carry a bear bell if trekking.
