Lake Kussharo, one of the biggest volcanic lakes in Akan National Park on Hokkaido. Deeply frozen during winter except for a few smaller spots where a lot of Whooper Swans gather for a few months. The Lake does attract a lot of people from all over the world, but mostly Japanese.
As harsh as Japanese people are for everything what's swimming in the Oceans, they are real killers on that point, so gentle they are for everything what has feathers by feeding them with every food they have to spend.
Best regards and a Happy, Happy Easter to all of you.
