Feel the Power of Mount Asama — Onioshidashi Park

Created by the lava that flowed from Mount Asama’s massive eruption, Onioshidashi Park showcases a rugged yet striking landscape shaped by nature’s force. As you walk through the park, alpine plants add color among the solidified lava, offering different views in every season — from spring greens to autumn hues and a white winter wonderland. Buses also run from popular destinations like Karuizawa and Kusatsu, making it easy to visit.

Soak in Japan’s Strongest Sulfur Springs — Manza Onsen

Located 1,800 meters above sea level inside Joshin’etsu Kogen National Park, Manza Onsen is famous for its milky-white water — the most sulfur-rich hot spring in Japan. Known since ancient times for its healing qualities, it offers open-air baths surrounded by mountains and sky. After a long soak, take a scenic drive toward Kusatsu Onsen, known as one of Japan’s most beautiful mountain routes.  

Winter Fun for Everyone — Ski & Snowboard in Tsumagoi

In winter, Tsumagoi turns into a snow-covered wonderland. Palcall Tsumagoi Ski Resort offers wide, gentle slopes perfect for beginners and families. From the 4 km summit run, you’ll be treated to a breathtaking view of Mount Asama rising in the distance — the kind of view you can’t help but photograph. After a day in the snow, unwind in one of the village’s onsen and enjoy the cozy warmth of Japan’s winter.  

Cycle Through Scenic Fields and Mountain Views

For a refreshing way to explore, rent a bike from “Tsumachari” and ride through Japan’s largest cabbage fields and rolling hills with Mount Asama in the distance. Every turn offers another photo-worthy view. Stop by Kumano Shrine, snap pictures with open skies as your backdrop, and enjoy a mix of nature, history, and local life. If you’re looking for a quiet, authentic side of Japan, Tsumagoi is a hidden gem waiting to be discovered.
