Shishigahana Marsh is a mysterious space created by a group of giant trees, including one of Japan's largest beech


Shishigahana Marsh

Within the wetlands of the Nakajimadai Recreation Forest are many mysterious big trees, such as Japan’s largest beech tree, King Agariko. No one knows for sure how the trees got their strange shapes, but many believe that it’s due to the trees growing on top of snow. If you walk about 40 minutes from Nakajimadai Recreation Forest, you’ll arrive at the spring pond “Detsubo”.

The wetlands here are home to some of the world’s rarest moss species that can only be found in Shishigahana, including the spherical “Chokai Marimo” which grow in the water.

Day Three


Maruike Pond

This popular and mysterious pond gets its sole source of water from Mt. Chokai’s underground streams. The pond itself is revered as a god, and is loved and respected by the locals. The emerald green water and hints of light shining through the plants and trees make this a very photogenic spot. The lighting depends on the time and season you visit, and changes the pond’s color.

Dohara Falls

Many people come here to draw water. Dohara’s name comes from the way Mt. Chokai’s subterranean streams gush out of the hillside. The falls don’t freeze even in winter, which means the waves of people coming to draw water from it never end. There are two waterfalls located next to each other, and it is said that each fall’s water has its own taste. Why not try both while you’re there?
