The Namitarou is a giant fish said to lurk in Takanami Pond in Niigata prefecture, Honshu, Japan.
Description
Eyewitnesses describe the fish as being from 2 to 4 meters (6.5 to 13 feet) in length. This cryptid fish has become quite well known in the area, and has even been photographed on occasion.
Place
Takanami Pond lies 540 meters (1,772 feet) above sea level in a wilderness area. It is an unusual place to find a cryptid of any type since the pond is not particularly large, and is only 13 meters deep at its deepest point. The surrounding area is famous for its camping, and is actually fairly developed as a tourist spot, with hiking trails, campgrounds, playgrounds, restaurants, and shops.
The pond has become a popular destination for people looking to get a glimpse of its mysterious inhabitant, and the wave the fish is said to produce when breaking the surface has become affectionately known as the “Tarou Wave,” from which the name “Namitarou” comes from ( nami is Japanese for “wave”).
Theories
The Namitarou is said to be most likely a giant carp of some variety. The two main candidates most often brought up are the grass carp (Ctenopharyngdon idella), or the silver carp (Hypophthalmichthys molitrix). Both of these species are widely found in Japan, where they are popular as a food fish. Grass carp can reach lengths of over 1.2 meters (3.9 ft) long and weights of up to 18kg (40lbs), while silver carp can get over 1 meter long (3.2 ft), and up to 27 kg (60 lbs). Perhaps a long lived specimen with its run of the pond has reached an even larger size?
There is also the possibility that a large species of exotic introduced fish could also be behind the sightings. The world’s largest species of carp is the Siamese carp (Catlocarpio siamensis), pictured above, which can be up to 3m (10 ft) long and 300kg (660 lbs) in weight. In Japan, where carp are valued as a food fish and are often kept for ornamental purposes, it is thought that an exotic species may have been imported from elsewhere and released into the pond.
