Japanese sandfish, commonly known in Japan as "Hatahata" is an important fish especially for Akita Prefecture. The fishing is carried out only for a limited period from the end of November to the end of December. A long time ago, Japanese people gave the name "God of thunder" to Hatahata, because Hatahata comes over with the winter thunderstorm from the depths of the ocean to the coastal area. The people of Akita believe that they are the "Gift of God" during the harsh winter. This is the reason that the fishermen head to the cold ocean every year with courage and hope.
