Usui Pass Lookout Tower

Located near the top of Usui Pass at an altitude of about 1,200 meters, the observatory park is on the border between Nagano and Gunma prefectures.
It is also known as a famous place for sunsets, and at dusk you can see Mt.
There are three ways to reach the viewing platform, and it takes about 10 minutes from Kyu-Karuizawa by car. If you are physically fit, you can walk to the gazebo on the 4-km promenade, or if you want to relax, you can take the popular retro red bus to enjoy the scenery.
