National Route 18 (国道18号, Kokudō jūhachi-gō) is a national highway connecting Takasaki, Gunma and Joetsu, Niigata in Japan. A section of the highway is designated as a part of the Japan Romantic Road.
Among other sections already finished, a bypass running on the west side of the Chikuma River from the extreme southern part of Nagano City to Ueda is currently under construction. As of 2008, only a small amount of sections of this bypass has been completed. The completed sections are in Ueda, just west of the Chikuma River, and in Chikuma from Inariyama to just south of Yawata.
