Wada Pass (和田峠, Wada-tōge) is a mountain pass in between Nagawa, Nagano, Chiisagata District and Shimosuwa, Nagano, at an altitude of 1,531m. Nakasendo passed through this mountain pass. Japan National Route 142 runs through the mountain pass by Wada Pass Tunnel and Shin-Wada Tunnel.


One of the pass over the Chikuma mountains. Shinano River runs on the northern of the pass to Nihonkai, Tenryu River runs on the southern of pass via Lake Suwa to Pacific Ocean.


There was the place obsidian was produced in Jōmon period around this pass.[1] The broad arrows made of obsidian produced from this pass were found in Kikonai, Hokkaido which is 650 km away from this pass.[2] Wada Pass is still famous for output of obsidian.[3] But, now, forbids collecting obsidian from the mount pass.[4]


Edo period

Nakasendo was constructed by Tokugawa shogunate, the mount pass belonged to the road. It is one of the most defensible chokepoints of the road because of heavy snow and precipitous topography. So, the government developed Nishi Mochiya quarter which located Shimosuwa and Higashi Mochiya quarter and Settai quarter that located Wada-shuku as asylum cover and rest house.

On 18 December 1864, "Tengu-to" which was organized by retainers of the Mito Domain combatted against allied forces which were organized by Suwa Domain and Matsumoto Domain. Eventually Tengu-to rode to victory.

From Meiji period to before the World War II

In 1876, Koyobashi Shido was open to traffic as motoring road. In 1925, 和田嶺自動車 (Wada Peak Automobile Road) was established and ran through this mount pass. But, this road was closed during winter due to heavy snow, so in 1933, Wada Pass Tunnel was constructed.

After World War II

Shin Wada Tunnel

In 1953, the road was registered as Japan National Route 142. Wada Pass Tunnel is narrow, so vehicles are not able to run as two lanes. Eventually, now, the tunnel is mutual contraflow. In 1978, Shin Wada Tunnel was open to traffic.

Japan National Route 142

Shin Wada Tunnel the distant of which is 14,777 m that has belonged to the Shin-Wada Tunnel Toll Road since 1978. Since 1 April 2022, a driver is able to pass through the former toll road without toll tickets,[5] so the road which runs over this tunnel has been gone free to pass though since 1 April 2022.[6][7]
