At the Toyako Onsen Illumination Tunnel, you can enjoy a gorgeous light tunnel that colors the winter nights of Hokkaido. In the bustling plaza of the Onsen town, a 70-meter-long tunnel and a 9-meter-diameter dome, made using about 400,000 LEDs, are set up to invite visitors into a fantastic world of lights. This illumination is a very popular spot for making winter memories. In the illumination area, multicolored tunnels and domes catch the eye, allowing visitors to stroll around while enjoying the light art. Each area has its unique characteristics, offering different visual experiences. Visitors can fully enjoy the atmosphere of the Onsen town at night, which is different from daytime. A major attraction of this event is that admission is free, and it can be enjoyed anytime during the period. It is friendly to first-time visitors and can be revisited repeatedly. The recommended way to enjoy is to warm up in Toyako Onsen after touring the fantastic light tunnel, making it a nice conclusion to your winter trip.
