I tried touring on Route 153!
First, Part 1, from Aichi (Minamichita) to Iida City, Nagano Prefecture. (It was 38 degrees Celsius on this day, so I moved slowly.)
Part 2 is here https://youtu.be/x64JncQGbh4
Impressed for the first time in Nagano Prefecture!
Everywhere was beautiful... just running on the national highway was fun ^ ^
