In Japan, the blue pond’s floating pillars
Japan News/Yomiuri
the blue pond’s floating pillars • The famed Shirogane “blue pond” tourist attraction in Hokkaido, Japan, is lit up at night, lending a mysterious glow to the withered larch trees and glassy water surface this month. The pond draws visitors because the water turns blue during the day due to a high aluminum content that scatters sunlight. The winter nighttime illuminations run from 5 p.m. to 9 p.m. daily through March 31.
