Introduction: The Soba Sanctuary and the Secret Sulfur Waters of the Akita Foothills
Nestled in a quiet forest clearing at the base of Mt. Akita-Komagatake, along the rushing mountain stream of the Sendatsu River, lies Komagatake Onsen (駒ヶ岳温泉). This hot spring enclave is a destination defined by its absolute mineral purity and its legendary culinary heritage. While most travelers head directly to the famous Tsurunoyu in Nyuto Onsen-kyo, savvy explorers stay at Komagatake Onsen—a sister inn to Tsurunoyu—to enjoy a more intimate, boutique atmosphere combined with what is arguably the best handmade Soba in Tohoku. For the international traveler, Komagatake Onsen offers a profound sensory journey: soaking in opaque, milky-white sulfur waters while watching the river rapids through the steam, indulging in a “Soba-kaiseki” feast, and experiencing the warm, artisanal hospitality of a single-inn sanctuary. It is the perfect restorative base for hikers, skiers, and those seeking a “Digital Detox” in the heart of the Akita wilderness.

The Healing Waters: The Milky “Medicine” of the Sendatsu River
The water at Komagatake Onsen is geologically intense, drawing its power from a unique volcanic vein shared with the lower Hachimantai system. It is a powerful Sulfur Spring.
The Visuals: The water emerges crystal clear but turns a striking, opaque milky-white or pale turquoise as it reacts with the oxygen in the valley air. You will notice “Yunohana” (mineral flowers) floating in the water—small white particles of concentrated sulfur.
The Sensation: This is a “Medicine Bath” (Kusuri-yu) in its most raw form. The sulfur content provides a powerful antiseptic effect for the skin, while the minerals promote intense peripheral blood circulation, warming the body from the core outward. The primary facility features indoor tubs built with fragrant Aomori Hiba (cypress) and a magnificent outdoor Rotenburo perched right on the riverbank. Soaking here in winter, as the steam rises against the backdrop of snow-heavy birch trees and the roar of the rapids, is a spiritual experience of the highest order.
Top Recommended Stay: Komagatake Onsen Lodge
- Komagatake Onsen (駒ヶ岳温泉): Address: 190-1 Tazawako Tazawa Sendatsuzawa. This is the only accommodation in the immediate clearing. It is a sophisticated, rustic lodge that prioritizes culinary excellence and mineral purity. The rooms are simple but elegant Japanese-style tatami spaces. The lodge is world-famous for its “Handmade Soba”—the owner is a master who grinds the buckwheat daily using mountain spring water. Staying here also grants you the exclusive privilege of a Free Night Shuttle to soak in the famous mixed-gender outdoor bath of Tsurunoyu in Nyuto Onsen. It is the premier choice for international foodies and onsen purists seeking a quiet alternative to the busier resorts.
- Tazawako City Hotels: Many travelers stay in the modern hotels near JR Tazawako Station (15 mins away) and visit Komagatake Onsen as a day-expedition for its superior water and lunch-time Soba.
Must-Visit Neighborhood Spots: Lakes and Volcanoes
Mt. Akita-Komagatake: The trailhead is accessible via shuttle bus from the nearby “Arupako” rest house. In summer, the mountain is covered in rare alpine flowers (Dicentra), and the peak offers a panoramic view of Lake Tazawa.
Lake Tazawa (Tazawako): A 15-minute drive down the mountain. Japan’s deepest lake (423.4m), famous for its sapphire-blue water and the golden statue of Princess Tatsuko.
Nyuto Onsen-kyo: Located 10 minutes further up the road, home to seven historic hidden inns. Exploring this district for “Onsen Hopping” is essential for any visitor to Komagatake.
Local Gastronomy: The Pinnacle of Buckwheat and Beef
Komagatake is considered a pilgrimage site for Handmade Soba enthusiasts.
Ju-wari Soba: Made with 100% locally grown buckwheat and pure mountain water. Try the “Soba-kaiseki” at the lodge, which includes various Soba-themed appetizers and crispy vegetable tempura.
Akita Beef & Kiritanpo: Try the local wagyu beef and “Kiritanpo-nabe” (rice stick hot pot) served in savory chicken broth.
Vegetarian/Vegan Survival:
For Vegans: This is a top-tier destination for plant-based eaters. The focus on buckwheat and mountain vegetables (Sansai) makes it easier to request vegan meals. At Komagatake Onsen, request the “Vegetable-only Kaiseki”—specify “Katsuo-dashi nuki” (No fish dashi). The local “Tazawako Tofu” is famous for its dense texture and rich soy flavor. We also recommend buying the local “Iburi-gakko” (Smoked Pickles)—a 100% vegan specialty with a deep, smoky flavor.
Cultural & Historical Context
The name “Komagatake” refers to the “Mountain of the Foal,” reflecting the traditional Japanese belief that the mountain is a protector of agriculture. Historically, the area was a vital territory for Ainu hunters before being explored by pioneers in the 19th century. Komagatake Onsen was developed as part of a visionary project by the owners of Tsurunoyu to create a “Gourmet Retreat” that could offer high-end culinary experiences while maintaining the rugged mineral identity of the region. Today, it stands as a symbol of Akita’s modern resilience—a place where the “Craft Spirit” of old Japan and the volcanic heritage of the north coexist in a spectacular alpine setting.
Practical Travel Tips for International Visitors
- Tattoo Policy: Komagatake Onsen is very international and extremely tattoo-friendly. Because it is a favorite for international hikers and skiers, the staff are used to foreign guests with ink. Small and medium tattoos are generally not an issue.
- Language Support: Excellent. The lodge staff speak basic English and provide English-language “Onsen Etiquette” guides. Menus for the Soba restaurant are increasingly bilingual.
- Cash & Payments: The lodge accepts major credit cards (Visa, Mastercard) for overnight stays and restaurant bills. However, the day-trip bath ticket machine and small local farm stalls are strictly cash-only (JPY).
- Access Advice: If you are arriving by **Akita Shinkansen**, get off at **JR Tazawako Station**. The local bus (“Nyuto Line”) departs every 30-60 minutes. If you have a **rental car**, it is a very easy drive from central Hirosaki or Morioka, but **4WD is mandatory in winter.**
2025-2026 Latest Updates
In 2025, Komagatake Onsen launched the “Soba & Soak Workshop,” where guests can learn to make their own buckwheat noodles in the morning followed by a private mineral soak. For the 2026 season, a new “Starlight Night Shuttle” will connect the onsen with the nearby ski resort for night-photography events during the blizzard season.
Safety & Manners
In the sulfur-rich onsen, remove all silver jewelry as it will turn black instantly. Always rinse your body thoroughly before entering the communal tub. Because the water is opaque, walk carefully to find the submerged steps. Be “Bear Aware”—carry a bear bell if you are hiking the forest trails behind the lodge. Finally, respect the quiet; many guests travel for days for the silence of the forest, so keep conversations in the baths to a soft whisper.
