[Semboku City, Akita Prefecture] Limited time only from May to June! Lake Akiogi where you can see mysterious trees floating on the dam lake

, there is a dam lake called Lake Shusenko where you can see a mysterious sight for a limited time This time, we will introduce the ``submerged forest of Lake Augigi''

What is Lake Shusenko?

Lake Akiogi is a dam lake located in the northern part of Lake Tazawa, and its official name is Lake Yoirobata Dam .

The Yorimahata Dam was the first multi-purpose dam built in the Omono River system for the purpose of flood control of the Tamagawa River and hydroelectric power generation that produced 15,700 kilowatts of electricity. It was named.

The name derives from the fact that the water supply area downstream of this dam fan-shaped , and ` `Oginomata Village'' among the submerged villages. It is said that the lake was named ``Akiogi Lake''.

If you go north on National Route 341 near Lake Tazawa from National Route 46, which connects Morioka City, Iwate Prefecture, and Akita City, Akita Prefecture, you will find it along the road.

A submerged forest that can only be seen for a limited period from May to June every year.

is famous for the fact that you can see the submerged forest only during a limited period in spring

The water level in the upper reaches of the dam lake, which is normally a wetland, is rising due to the influx of spring snowmelt. This is a phenomenon in which trees growing in wetlands become submerged under water, making them appear as if they are floating on top of the water.

It is famous as a limited-time sight that can only be seen until mid-June when the water supply to the rice fields begins

Additionally, the lake's surface turns a stunning cobalt blue color due to the leaching of lime components , which is artificially done to neutralize the acidic water quality of the Tamagawa River. Currently, neutralization and stirring work is being carried out at Lake Hosen upstream. Therefore, Lake Hosen has a similar light blue color.

By the way, as you can see from the above, the hot water at Tamagawa Onsen and Shin Tamagawa Onsen on the shores of Lake Hosen is strongly acidic with a pH of 1.2. It is said to be known as the most acidic spring in Japan

Where can you see submerged forests?

As mentioned above, you can see the submerged forest upstream of Lake Akiogi.

After you see Lake Akiogi, if you continue north on National Route 341 for a while, you will come to a bridge called ``Shin Tamagawa Bridge'', and you can see the most beautiful view of the submerged forest on top of that bridge.

During the submerged forest season, many tourists enjoy taking photos as shown in the photo above.

Lake Shirakawa in Iide Town, Yamagata Prefecture is famous for canoeing in a submerged forest, but there were also people enjoying canoeing here at Lake Akiogi. Looks like it feels good.

lastly

There are many tourist spots where you can see seasonal scenery, but I think Lake Akifan is also an interesting spot that is worth seeing. It's also close to the famous sightseeing spot "Lake Tazawa", about 30 minutes by car, so it might be a good idea to add it to your list of spring sightseeing spots at Lake Tazawa!

@neft_tohoku 🌲 Submerged forest of Lake Akifan in Semboku City, Akita Prefecture 🌲 A sight seen from May to mid-June when the lake swells with melting snow. The color of the water is lapis lazuli because the hot spring water from Tamagawa Onsen located upstream flows into it. #Akita prefecture #Semboku city #Autumn fan lake #submerged forest ♬ Original song – Tohoku Rokken trivia media | NEFT
