The Phantom "Kuchiboso Ao-unagi" That Can Only Be Caught in Lake Mikata
Mikatagoko (Five Lakes of Mikata) is known as a production area for natural eels, which are now extremely rare. Among them, the "Kuchiboso Ao-unagi" caught in Lake Mikata has thick and soft meat. It is characterized by a light and elegant taste despite being fatty.
This is because while natural eels in other regions eat goby fish and such, Kuchiboso Ao-unagi eats soft food like lugworms and long-armed shrimp. Their jaws do not develop because they eat by pecking, so their mouths are pointed. Also, the muddy lakebed is suitable as a living environment, which is the reason why fatty eels grow.
There are almost no natural eels in Japan that have migrated upstream from the sea, and the natural eels in Lake Mikata are also those that were released as fry and grew up. The owner of "Unagi Tansui," who is also a fisherman, has dedicated himself to the regeneration of Lake Mikata's eels, including the Kuchiboso Ao-unagi.
