Blue Pond

The Blue Pond in Hokkaido is a fascinating mix of nature and human engineering, created to manage erosion from Mount Tokachidake. Its striking color comes from minerals like aluminum in the water from Shirahige Falls, but as you’ve pointed out, it’s not always the vibrant blue seen in advertisements. Weather, seasons, and lighting all play a role in its ever-changing look, making every visit a unique experience. Your original photo captures its real charm—authentic and unfiltered beauty.
