Have you ever felt the need to escape the hustle and bustle of daily life and reset your mind? If so, Teshikaga, located in eastern Hokkaido, is the perfect destination. This serene town boasts breathtaking natural landscapes, rich cultural heritage, and the deep connection of its people to the environment they call home.

From Lake Kussharo, Japan’s largest caldera lake, to the crystal-clear waters of Lake Mashu, and the active volcano Mount Io (Atosanupuri), Teshikaga’s scenery feels like a window into the Earth’s primal beauty. On my journey here, I discovered tranquility and clarity like never before.
About Teshikaga
Nestled within Akan-Mashu National Park, Teshikaga is a nature lover’s paradise. With 65% of its land designated as a conservation area, the town is a testament to the harmony between nature and community. The region’s iconic Kussharo Caldera is surrounded by the Akan volcanic range, creating a dramatic and awe-inspiring landscape.

This area has long been home to the Ainu, a local indigenous people, whose cultural presence is reflected in place names like Atosanupuri, meaning “bare mountain.” Beyond its natural beauty, Teshikaga strives to balance tourism with environmental preservation. Recognized as one of the Green Destinations Top 100 in 2023, it has earned global acclaim for its sustainable practices.
A Journey into Nature
After a two-hour drive from Kushiro Airport, my first stop was an overlook above Lake Kussharo. There, I was warmly greeted by a local sustainability coordinator, Ms. Kinase, who brewed fresh coffee as we admired the lake’s serene surface.
“This is where your journey begins,” she said, as we gazed at a landscape unlike anywhere else in Japan.

We began with a visit to the Tsutsujigahara Nature Trail, led by a knowledgeable local guide who pointed out unique flora. “These dwarf pines are typically found at elevations over 1,000 meters,” the guide explained, noting how volcanic activity allows them to thrive at lower altitudes here.

By October, the trail was adorned with vibrant hana-goke mosses, while in June, the landscape transforms into a sea of white with blooming iso-tsutsuji flowers.

Emerging from the forest, we were greeted by the sight of Atosanupuri, its stark, volcanic slopes a striking contrast to the surrounding greenery.

As we approached Atosanupuri, the vivid yellow, needle-like crystals came into view—so striking they seemed almost unreal. These formations, along with the numerous fumaroles scattered across the area, are designated as “special natural tourism resources,” carefully protected for their unique geological and ecological value. Once a hub for sulfur mining, the mountain now stands as a testament to the dynamic beauty of nature, cherished and safeguarded by the local community.

Atosanupuri Trekking
The highlight of my trip was the Atosanupuri Trekking Tour, an initiative by the Teshikaga Eco-Town Promotion Council. This guided experience offers exclusive access to protected areas, ensuring minimal environmental impact while providing a safe and enriching adventure.

Accompanied by Yukiko, a certified guide, we began our ascent. As we climbed, Yukiko shared stories of the mountain’s mining past and the community’s efforts to preserve its natural beauty. Sulfur vents emitted vivid yellow crystals, and the bubbling hot springs seemed to breathe life into the rugged terrain.

As the climb grew steeper, my breath grew shorter, but we finally reached the summit—the highest point accessible to hikers. Taking a break, Yukiko shared more of the region's story:
“In the early 1990s, this area was bustling with tourists during the tourism boom”.
But as visitor numbers declined, the local economy stagnated, leading to issues like abandoned buildings and environmental degradation. However, rather than returning to mass tourism, the community sought a different path. They wanted to protect the resources they hold dear and create tourism that offers visitors an authentic connection to their nature and culture while sustaining the local economy.
This tour itself is a testament to their vision. It was developed as part of the community’s efforts to promote sustainable tourism, with part of the tour fees directly supporting environmental conservation and the maintenance of the trekking trails.

This tour is more than just an opportunity to enjoy nature; it’s a travel experience that gives back to the community and takes a meaningful step toward the future of sustainable tourism. It’s an invitation to travelers to recognize their responsibility and appreciate the thoughtful systems the region has established to protect its resources. I felt this tour was a true model of coexistence between humans and nature.
“Shall we head back down?” Yukiko said, her voice breaking the calm silence.

With Yukiko’s encouragement, we started our descent along the path leading to the base. Ahead lay the Tsutsujigahara Nature Trail we had explored the day before, and beyond it, the shimmering surface of Lake Kussharo. Surrounded by this vast wilderness, I felt a renewed connection to the natural world as we made our way back, savoring every step down the trail.
Kushiro River Canoeing and Culinary Delights
Another unforgettable experience was canoeing down the tranquil Kushiro River. Guided by a passionate local who had fallen in love with Teshikaga’s natural beauty, we floated through serene waters, pausing for tea as we listened to birdsong and spotted wildlife.
The journey ended with an exhilarating rush through gentle rapids, a thrilling conclusion to our river adventure.

For lunch, we stopped at the SoRa Auberge, where chefs craft creative dishes from fresh, locally sourced ingredients, including Hokkaido wagyu and seasonal seafood. The combination of exquisite flavors and stunning views from the dining room’s large windows made for a perfect end to the day.

The restaurant is set in expansive grounds, with lush lawns stretching out in every direction. Each dish was a masterpiece, showcasing the chef's skill and creativity, while the scenery outside the windows heightened the sense of connection to Hokkaido's natural abundance.
SoRa Auberge also offers charming guest rooms, making it a sought-after destination for those who wish to enjoy an extended and relaxed stay.
Hot Springs and Accommodations
Teshikaga offers a variety of unique and delightful accommodations.
During my stay, I chose Bettei Suikazura, located in Kawayu Onsen, which features a rare and highly acidic hot spring. The soothing waters were perfect for unwinding, and the property includes a cozy lounge, ideal for relaxing alone or with family. One of the highlights was enjoying local Japanese cuisine, such as Wagyu beef prepared in the distinctive "Sulfur Mountain Grill" style, served in a private dining room—a truly memorable experience.

Another exceptional option is WAKKANUPURI, a one-group-per-day retreat offering unparalleled privacy. From the large windows of the guest room, you can enjoy exclusive views of stunning Lake Kussharo. The sandy beach beside the lodge provides direct access to the lake for canoeing, offering a private gateway to Teshikaga’s natural wonders. Meals are served in a private living-dining pavilion, where exquisite Japanese cuisine is crafted with the day’s finest ingredients. This accommodation is perfect for those seeking a serene and luxurious experience in Teshikaga.

Lastly, there is the Kussharo Lake Onsen Hotel, another one-group-per-day boutique hotel that provides tranquil views of the surrounding forest. A highlight of this property is its proximity to the Kussharo Sauna Club, a must-visit for sauna enthusiasts. Overnight guests enjoy unlimited access to the sauna from evening until morning, while daytime visitors can also use the sauna facilities without staying overnight—a popular draw for locals and tourists alike.

At the Journey’s End
The three days I spent in Teshikaga were more than just a reset for my mind—they offered me a fresh perspective. I was deeply moved by the profound connection between the local community and their land, the intricate beauty of nature, and the rich cultural heritage they strive to protect.
