World Wide Fund for Nature Japan (Minato-ku, Tokyo, Chairman: Takejiro Sueyoshi, hereafter WWF Japan) announced that the lights-out action took place in countries and regions around the world for 'EARTH HOUR 2026' on Saturday, March 28, 2026. Earth Hour is a global environmental action where people around the world turn off their lights for one hour on the same day and time to express their intention to prevent global warming and conserve biodiversity. Every year on a Saturday in late March, regions turn off their lights for one hour starting at 8:30 PM local time. This year, starting from the South Pacific nations near the International Date Line on March 28, regions turned off their lights for one hour as 8:30 PM local time approached, and people's thoughts circled the globe along with the lights-out relay.
For this year's lights-out action, many landmarks worldwide turned off their lights, including the Sydney Opera House in Australia, Marina Bay Sands in Singapore, the Eiffel Tower in France, the Sagrada Familia in Spain, the Brandenburg Gate in Germany, and the United Nations Headquarters in New York. In Japan, landscapes such as the Atomic Bomb Dome, Goryokaku Tower, Tokyo Tower, Tokyo Skytree(R), and Rainbow Bridge implemented the lights-out. The next Earth Hour is scheduled for Saturday, March 20, 2027.
■ The total number of organizations in Japan that declared their intention to implement environmental actions, including turning off lights, reached 4,179, surpassing last year.
In addition to the landscape lights-out actions, the total number of local governments and companies that registered with WWF Japan to implement various environmental actions, including turning off lights, increased by over 600 from last year to 4,179, and the number of individual participants was 936 (as of April 1).
