The Shirasuna River flows through the Kuni area of Nakanojo Town in Gunma Prefecture, following National Routes 405 and 292. The scenic beauty of the gorge can be enjoyed from your car window as you drive along the route. During autumn, the foliage is especially stunning, with the vibrant colors on the rocky areas along Route 405 being particularly impressive. Several bridges offer great views of the Shirasuna Gorge, where the contrast between the autumn leaves and the emerald-green river is truly captivating.
