Driving Japan | Route 143, a mountain pass in Nagano Prefecture born in the Meiji Era | GoPro11

Route 143 runs from the intersection of Route 19 in Matsumoto City, Nagano Prefecture, through Azumino City, Nagano Prefecture, Chikuhoku Village, Higashi-Chikuma County, and Aoki Village, Chiisagata County, to the intersection of Route 18 in Ueda City, Nagano Prefecture.
The Jizo Pass and the Aoki Pass are narrow roads with 1 to 1.5 lanes, and large vehicles are not allowed to pass through.
The Aiyoshi Tunnel at Jizo Pass and the Akedōshi Tunnel at Aoki Pass were both constructed in 1890, and although they have been reconstructed, they are the oldest existing national highway tunnels in Japan.
Both tunnels are narrow, and the Aikichi Tunnel is equipped with a traffic light system that allows cars to pass alternately.
