It is an old stratovolcano facing the Mt. Azuma-kofuji of Okenuma in Bandai Asahi National Park in Fukushima Prefecture and the southern part of Jododaira. At the end of April, when I went to see the fresh green and blue lake, there was still a lot of snow.
It was difficult to get to the shooting location, but I was impressed by the natural beauty reflected in the dark blue surface of the dark blue lake with the remaining snow on the lakeside and the fresh greenery of the trees that have begun to sprout!
It is a recommended hidden gem.
