Tucked away in the historic post town of Narai-juku, this cozy spot offers a genuine taste of the Kiso Valley. After you've wandered the beautifully preserved Edo-period street, step inside to warm up with a bowl of authentic Shinshu soba. For a truly local experience, try the 'Toji Soba,' a unique dish where you swish the noodles yourself in a hot, savory broth—it's the perfect way to refuel and soak in the timeless atmosphere of the old Nakasendo trail.
