Landfill Reborn as Butterfly Reserve (Japan in Photos)

Great purple emperor butterflies rest on leaves at the site of the Yatozawa landfill in Hinode, Tokyo, on June 20, 2017. The reintroduction of the violet-hued ōmurasaki, the Japanese national butterfly, is part of restoration efforts at the now shuttered facility by the Tama Regional Association for Waste Management and Resource Recycling, which uses the insects to help assess recovery of the surrounding environment.
