Toro Nagashi in Japan; or "Lantern Offerings on the Water". Traditional Japanese beliefs state that humans come from water, so the lanterns represent their bodies returning to water. At the end, the laterns are retrieved and recycled.
Hiroshima Lantern Festival: Held annually in August. Each lantern is inscribed a message that family and friends want to send to the deceased, or the wishes of nuclear weapons and the bloody war will never happen.
