Blue Pond: Hokkaido’s famous Biei Blue Pond was made by accident, as the by-product of attempts to control mudslides. Aluminum from the soil seeping into the water scatters the sunlight causing the pond to look blue. But depending on the time of day and the light, the reflection can also look green and every shade in between. #bluepond #blue #bieibluepond #hokkaido #hokkaidoblue
