About two and a half hours by car from Tokyo, Ikaho Onsen lies just beyond the Shibukawa-Ikaho Interchange on the Kan-Etsu Expressway. Nestled in the mountains of Gunma Prefecture, this historic hot spring town is known for its nostalgic charm, making it a perfect destination for a weekend road trip and overnight stay.
The centerpiece of Ikaho Onsen is its iconic 365-step stone staircase, flanked by souvenir shops, cozy eateries, and vintage shooting galleries that evoke the atmosphere of a bygone era. Along the way, you’ll find public bathhouses and footbaths—perfect spots to take a short break. As you ascend, the view gradually opens up, offering scenic vistas unique to elevated onsen towns.
What sets Ikaho apart is its two distinct types of spring water: “Kogane-no-Yu” (Golden Hot Spring) and “Shirogane-no-Yu” (Silver Hot Spring). The former, rich in iron, takes on a distinctive reddish-brown color and is said to warm the body to its core. Its scent and hue enhance the traditional onsen experience, deepening one’s connection to the town’s historic ambiance.
For accommodations, consider staying at a retro-style ryokan that retains the elegance of the Showa era. These inns offer spacious tatami rooms, polished wooden staircases, and a serene atmosphere that encourages guests to slow down. In recent years, such classic inns have gained renewed popularity for their nostalgic appeal. Many have been thoughtfully renovated to preserve their old-world charm while offering modern comforts, providing a unique and memorable stay.
Dinner in Ikaho often features the mountain flavors of Gunma Prefecture. Delicacies such as sukiyaki made with Joshu beef, salt-grilled river fish, and seasonal vegetable stews offer a taste of rustic Japanese cuisine, rich in simplicity and depth. Many inns serve meals around an irori (traditional sunken hearth) or in the privacy of your room, allowing for a quiet and relaxing dining experience. After your meal, unwind with a glass of local sake or a nostalgic bottle of milk in the ryokan lounge.
The next morning, take a stroll through the onsen town before heading out by car to nearby attractions such as Ikaho Green Bokujo (a family-friendly farm) or Lake Haruna. Just a 10-minute drive away, the farm offers hands-on experiences with animals, barbecue dining, and fresh soft-serve ice cream—popular among both families and couples. Lake Haruna, surrounded by seasonal natural beauty, provides a tranquil conclusion to your scenic drive.
On the return journey to Tokyo via the Kan-Etsu Expressway from the Shibukawa-Ikaho IC, consider stopping at one of several local roadside stations (michi-no-eki) along the way. These spots offer fresh local produce and regional souvenirs—perfect for savoring the lingering memories of your trip.
Ikaho Onsen is a rare gem where visitors can experience both the soothing charm of hot springs and the nostalgic spirit of the Showa era—all just a short drive from Tokyo. Its enduring atmosphere, untouched by time, offers a fresh perspective to modern travelers. If you’re looking to slow down and reconnect with the simple joys of travel, point your steering wheel north for a truly restorative weekend escape.
