[Aizu Tour & Seasonal Exploration] A forest standing in the lake that appears only for one month in spring ── The submerged forest of Shirakawa Lake


山形県西置賜郡飯豊町。白川湖。 毎年春、雪解け水で湖が満水になる3月下旬から5月中旬の約2ヶ月の間だけ、湖の水面から木々が立っているように見える、幻の景色が現れます。 それ以外の時期に訪れても、ここはただの貯水池です。けれど春のたった数週間だけ──。

Drive along National Route 121 from Aizu towards Yonezawa, and further into the foothills of the Iide Mountain Range, where the lake is located.

In Yamagata Prefecture, Nishimurayama District, Iide Town, Shirakawa Lake.

It is the reservoir of the Shirakawa Dam, completed in 1981 (Showa 56). Usually, it is a quiet dam lake surrounded by greenery in the mountains.

However, at specific times in spring, this lake shows a completely different expression.

From the surface of the lake, many trees rise up.

The "submerged forest" that appears only for one month in spring.

This scenery is called submerged forest.

At the bottom of the lake, there was originally ground where white willow trees grow. Normally, the white willow trees are just slightly submerged under the water.

But in spring──.

Meltwater from the mountains of the Iide mountain range flows rapidly into the dam. The water level of the lake rises dramatically. As a result, the trunks of the white willow trees at the bottom of the lake become submerged up to the middle.

Then, a scene appears where "the trees look like they are growing out of the water".

This can be seen only for about two months from late March to mid-May. This is the time when the lake is full and the white willows begin to sprout leaves.

By summer, the water level drops, and the white willows return to ordinary riverside trees.

A mystical morning mist.

The best time to see the submerged forest is early morning.

In the morning, a thin mist rises from the surface of the lake. The fresh green white willows float there. Only the outlines of the trunks and leaves can be seen through the mist. It looks like a scene lost in an ink wash painting.

If you go out onto the lake by canoe, you can paddle through the mist. The experience of looking up at the submerged forest from just above the water's surface while slipping between the trees has a depth that cannot be conveyed through photographs.

Walking after knowing, Lake Shirakawa

When we guide our guests at Lake Shirakawa, we always start by telling them, "This view can only be seen for two months a year." Many guests are surprised and say, "Oh, I didn't know that."

The fact that you were able to see a seasonal landscape itself becomes a harvest of the journey. It will remain in your memory as "the year I saw the submerged forest of Lake Shirakawa in spring."

When you visit during the rainy season or summer, it just looks like a regular dam lake. The autumn foliage isn't bad either. However—once you see that phantom-like scenery in spring, it becomes a place with a mysterious power that makes you want to see it again.
