Here is the secret Ponhoro on the web page of Shiretoko Forest Center.
However, here is the secret Ponhoro I see..... Where is the swamp? Illusion?
In fact, there's neither entrances nor signposts.
Fallen trees and vegetation stop the footpaths, so I got lost.
Ponporo, in the language of Japanese indigenous Ainu people, means small-big. As the snow melts and makes its way deep underground, and it rises again in Ponhoro. As the weather gets warmer and warmer, the swamp becomes small.
To my surprise, what I experience is not the swamp but the total silence in Ponhoro. No humans, no animals, even no wind make any sound.
No sign here. Please kindly advised that
