The starry night sky takes your breath away.

Stars over Lake Mashu

With no mountains blocking the view, the area around Lake Mashu offers an incredible 360-degree view of the stars at night. If you're lucky, you might even see a shooting star or a satellite. Even on nights when the stars cannot be seen, you'll get to experience the great outdoors in the depths of the night with all five senses - you can learn about the constellations, see Lake Mashu glinting in the faint starlight and look out at the nightscape of Kushiro in the distance. *If booking at short notice, please inquire by phone to Tourism Teshikaga: 015-483-2101
