Toyako Onsen is a popular hot spring resort along Lake Toya.
Toyako Illumination Tunnel is a tunnel of light created by approximately 400,000 light bulbs.
The 70-meter-long corridor and its 9-meter-diameter dome are like an entrance to a fantastic world.
Afterwards, you can warm up yourselves by soaking into the onsen (hot spring)!
