【Driving in Japan】National Route 151 : Shinshiro – Toei, Aichi [Insta 360 Ace Pro 4K60P]

National Route 151 is a major highway that runs from Iida City in Nagano Prefecture through the mountainous region of Aichi Prefecture (Oku-Mikawa region) to Toyohashi City. In addition to its mission of connecting regions, it also functions as a “lifeline” connecting the mountain villages of Southern Shinshu and the Oku-Mikawa region, playing an important role in promoting industry and supporting local life.

This time, I drove the entire route from its end point in Toyohashi City to its start point in Iida City. Because the recording was long, I will be releasing it in several videos.

The second video shows the section from the vicinity of the “Mokkuru Shinshiro Roadside Station” in Shinshiro City, Aichi Prefecture, to Toei Town in the same prefecture. After branching off from National Route 257 heading towards Hamamatsu City, Shizuoka Prefecture, the road enters the mountainous area. The road runs along the Ure River, a tributary of the Toyokawa River, and the surrounding area is a scenic spot known as “Houraikyo Gorge,” famous for its autumn foliage.

  1. 前回に続いて国道151号の愛知県内区間ですね。
    前半はまだ市街地を通っていますが、後半は徐々に山岳区間に入り、交通量も少なめになり割と快走路ですね。
    また、この区間は三遠南信自動車道とほぼ並行していて、現在建設中の鳳来峡IC~東栄ICの区間の開通を控えているので、開通後は国道の交通にもさらなる変化がありそうですね。
