Hiroshima Castle and Rihga Royal Hotel Hiroshima to Turn Off Lights for Earth Hour 2024

The Righa Royal Hotel Hiroshima and Hiroshima Castle will participate in the world’s largest environmental campaign “EARTH HOUR 2024,” advocated by the World Wide Fund for Nature (WWF), with lights-out activities such as illuminations being implemented from 8:30 p.m. on Saturday, March 23, 2024.


As one of the initiatives to promote Sustainable Development Goals (SDGs), EARTH HOUR is a WWF project that demonstrates a commitment to the Earth and biodiversity conservation by turning off lights at the same time worldwide on the same day.

At the Righa Royal Hotel Hiroshima, outdoor lighting logos will be turned off, and the lobby and restaurants will be dimmed while LED candles will be used for ambient lighting.

At Hiroshima Castle, the illumination of the main keep will be turned off at 8:30 p.m. Since March 22, the day before EARTH HOUR, is the expected date for cherry blossoms to bloom in Hiroshima, when the cherry blossoms at Hiroshima Castle start to bloom, they will be illuminated. However, since the lights will be turned off early on the 23rd, those planning to enjoy the cherry blossoms at night need to be aware of this.
