Located around Akaya Lake, formed by the Aimata Dam in Gunma Prefecture, this area is known for its vibrant autumn colors. Popular spots include Sarugakyo Onsen, the vicinity of Akaya Lake and Aioi Bridge, as well as along Route 270. There are walking paths and observation decks along the lakeshore, offering leisurely views of the lake and the Tanigawa mountain range. The area near Mikuni Pass, reached via the old Mikuni Highway from the Mikuni Tunnel on National Route 17, is also a famous site for autumn leaves, with well-maintained nature trails popular among hikers. The best time to see the foliage is from late October to mid-November each year.
