The Enasan Tunnel is a major road tunnel piercing Mount Ena, linking Gifu and Nagano prefectures. As one of Japan's longest road tunnels, it is an impressive feat of engineering, reducing travel time across the mountainous region. While driving through, visitors experience a well-lit, ventilated passage that cuts through solid rock. The tunnel's portals offer dramatic views of the surrounding peaks. It's a practical yet awe-inspiring route for travelers exploring the Kiso Valley.
