Lake Shikotsu’s forest has more than 90 percent of natural grown woods. And the Bifue forest, on the west shore of the lake, has the most primary environment. “Pifyi” is the derivation of the “Bifue”, meaning a river in a pebbly field. Clear water of Bifue River runs into Lake Shikotsu.
There are trees of more than 300 years old in this area. They are oaks and Japanese Judas Trees. Naturally, without notice, people call this area “Gigantic-Tree Forest”. And in the sandbank of Bifue River, there are big tree’s stumps that had died by the affection of lake.
It’s quite easy to reach the Kyoboku-no-Mori. Go the Route 276 that runs south shore of the lake to the direction of Toya and Otaki. Then you will turn right before Bifue tunnel. Now you are on the Route 78. Route 78 is closed where you stride over the Bifue River. It is closed from Bifue to Okotan. Before that, there’s a track to Bifue campsite. Kyoboku-no-Mori spreads along this track, and a fine sign was set in recent years.
We recommend you to park the car near the side of alley, and then walk around. It is nice to take the pictures wherever you like with a big tree that seems to have spirit inside.
