Become a EC Supporter

This year will mark the 33rd Earth Celebration. The festival has reached this milestone thanks to the support of many people on Sado Island and further afield. We would like to express our sincere gratitude for the generosity of all EC supporters to date.

Although we are not able to physically invite guests to Sado Island, we will be delivering the event to the world through free live streaming online.
Through doing this, we wish we are able to introduce more of Earth Celebration and Sado Island to as many people as possible within Japan and overseas, and hoping to invite more visitors next year and beyond.
