Towadako Onsen (十和田湖温泉)

Introduction: The Sacred Caldera Sanctuary and the Heart of the Mirror Lake

Located on the majestic southern shores of Lake Towada, in the historic Yasumiya district, lies Towadako Onsen (十和田湖温泉). This hot spring enclave is the spiritual and logistical heart of the Towada-Hachimantai National Park. While its name is often used to describe the wider region, the thermal springs at the lakeside (Yasumiya) are defined by their absolute proximity to Japan’s largest caldera lake. Towadako is a landscape of profound mists, ancient shrines, and the iconic “Statue of Maidens” by Kotaro Takamura. For the international traveler, Towadako Onsen offers a profound sensory journey: soaking in mineral-rich waters while watching the sun set over the mirror-like lake, exploring the ancient birch and cedar forests of the shoreline, and witnessing the unpolished, resilient hospitality of the northern frontier. It is a place of spiritual grounding, maritime peace, and a restorative warmth that captures the heroic soul of Aomori’s volcanic interior.

Key Information Table

The Healing Waters: The “Mirror Lake” Silk

The water at Towadako Onsen (Yasumiya) is geologically distinct, drawn from volcanic veins beneath the lakebed. It is primarily a Sodium-Chloride / Bicarbonate Spring.
The Visuals: The water is crystal clear and odorless, with a notably “soft” and slippery texture.
The Sensation: It is a classic “Bijin-no-yu” (Beauty Water). The bicarbonate content gently dissolves dead skin cells, while the chloride content forms a “mineral veil” that traps body heat—a vital trait for survival during the chilly nights of the northern highlands. The facility at Towada Prince Hotel and other lakeside ryokans feature outdoor Rotenburo baths where the cool lake breeze provides a refreshing contrast to the hot mineral waters. Soaking here at dawn, as the mist clears from the lake surface and the reflection of Mt. Towada appears, is a meditative experience of the highest order.

Must-Visit Neighborhood Spots: Statues and Shrines

The Statue of Maidens (Otome-no-zo): A short walk from the onsen area. The iconic bronze statue by Kotaro Takamura is the symbol of the lake.
Towada Shrine: A profound spiritual site located in a dense cedar grove. It has a 1,200-year history and is dedicated to the water spirits of the caldera.
Lake Towada Ferry Cruise: Take a boat from Yasumiya to Utarube for the best views of the “Okhotsk Blue” water and the dramatic cliffs of the peninsula.

Local Gastronomy: The Bounty of the “Deep North” Lake

Towadako is famous for its Himemasu (Kokanee Salmon).
Himemasu Sushi & Salt-grill: This freshwater salmon is native to the cold, deep waters of the lake. The meat is sweet, firm, and considered a luxury delicacy.
Mountain Veggie Tempura: In spring and summer, the local inns serve wild ferns and roots gathered from the surrounding National Park.
Vegetarian/Vegan Survival:
For Vegans: This area is a producer of Hokkaido/Aomori Soybeans. At the hotels, you can request “Mountain Vegetable Soba”—specify “Katsuo-dashi nuki” (No fish dashi). The local “Towadako Tofu” is famous for its dense texture and rich soy flavor. We also recommend buying the local Aomori Apple Juice at the ferry terminal.

Cultural & Historical Context

The name “Towada” comes from the Ainu word “To-wata”, meaning “the lake.” Historically, the area was a sacred site for the Ainu people, who viewed the caldera as a place of spiritual origin. Towadako Onsen was developed during the Taisho and Showa eras to turn the lake into a world-class tourism gateway. Today, it stands as a symbol of Hokkaido/Aomori’s commitment to “Sustainable Eco-Tourism,” protecting the lake’s incredible transparency while welcoming global explorers.

Practical Travel Tips for International Visitors

• Tattoo Policy: Towadako Prince and the larger hotels are quite international and generally tattoo-friendly. For the smaller communal baths, using a waterproof sticker is recommended as a courtesy to the local residents.
• Language Support: Excellent. This is one of Aomori’s top tourist destinations, and English-speaking staff are often available at major hotels and the Visitor Center.
• Cash & Payments: Major hotels accept credit cards. However, the local bus (JR Bus Tohoku) and small harbor shops are strictly cash-only (JPY).
• Access Advice: If you are traveling by bus, take the JR Bus “Oirase-go” from Hachinohe Station. It is a scenic ride that drops you right in the center of Yasumiya. If driving, be aware of the narrow mountain pass roads in winter.

2025-2026 Latest Updates

In 2025, Towadako Onsen launched the “Caldera Starlight Night,” where guests can take a guided boat tour to the center of the lake for stargazing followed by a midnight mineral bath. For the 2026 season, new “Forest Meditation Decks” are being built along the Yasumiya shoreline for better sunset photography access.

Safety & Manners

In the onsen, always wash your body thoroughly before entering the tub. Because the water is clear and soft, follow the “No Towel in Water” rule strictly. When visiting Towada Shrine, do not shout or make loud noises. Finally, respect the quiet of the lakeside; Towadako is a sanctuary for migratory birds and spirit, so keep noise levels to a minimum in the evening.
