Otori Pond in the Asahi Mountains, Yamagata Prefecture.
Known as the habitat of the unidentified large fish Takitarou, it is also the model for "Oike no Takitaro" depicted in the manga "Fisherman Sanpei".
Until now, witness testimonies of locals have been introduced and surveys using fishfinders have been conducted, but the reality is still a mysterious fish.
What is "Takitarou"? Mr. Koken Sorimachi, who lives in Gunma prefecture, is one of the anglers who was attracted to such an unknown existence.
He brought in a tackle that can be said to be over-engineered in everyday char fishing, and he closely followed the fishing trip to chase the legendary big fish that he was interested in.
