Discover Serenity in the Heart of Kumamoto’s Natural Beauty
Tucked along National Route 218, Misato Samata no Yu is a vibrant roadside station nestled in the serene countryside of Minamiboso, just a short drive from the Shokai IC on the Kyushu Expressway.

Insider Tips
Visit during the October Hot Spring Festival or at 11:30 AM to see the heart-shaped bridge reflection at the famous Futamata Bridge.
- Best Arrival Time: Visit the roadside station by 9:00 AM on weekdays to access the full selection of seasonal produce at Wakuwaku Kan, as the most popular items like fresh mountain vegetables and local tofu pickles are often sold out by 11:00 AM.
- Hidden Gems: At the Wakuwaku Kan (farmers’ market), look for the hand-packed "Kabocha Cheese Croquettes" near the front display—they are made daily using locally grown squash and sold only until 1:00 PM.
- Weekend Special: On weekends, visit the restaurant "Ishidai no Gō" between 11:30 AM and 1:00 PM to enjoy the seasonal "Yamame Salt-Baked Set" and "Dago Jiru Set," which are not available during weekdays.
- Best Time for Photos: Arrive at Futamata Bridge (Two-Stream Bridge) at 11:30 AM during October through February to capture the heart-shaped reflection of the bridge in the river, which appears for about 30 minutes and is a designated "Lovers’ Holy Land."
- Parking Tip: Use the western parking lot near the EV charging station when visiting during peak hours, as it offers easier access to the restaurant and Wakuwaku Kan, while the main lot fills quickly during events.
- Information Advantage: Access the 24-hour information corner during evening visits to check real-time road conditions and upcoming event schedules, including the annual "Samatano Yū Hot Spring Festival" on October 18, which includes local performances and food stalls.
- Avoid Wait Times: If you plan to use the hot spring facility, arrive before 4:00 PM on weekdays to avoid the mid-afternoon rush, as the facility sees heavy usage after 5:00 PM, especially on weekends.
