The Light Down campaign will start again this year to offer an opportunity to think about climate change by turning the lights down around us.
It is about the future of the earth and our day-to-day life. Isn’t it a little romantic to be lost in thought at night when the lights are turned off? Let’s connect together in the night sky on the day of summer solstice and Tanabata.

Goryokaku Tower joins the Reduction of CO2 Emissions and the Light Down Campaign again this year. For two days of the Summer Solstice Light Down and Cool Earth Day Light Down, the lights of the tower will be turned off for two hours from 8 p.m. to 10 p.m.
