Its a robotic fish! NO, its a real fish! NO, its a …its a not sure. Its a 31-inch-long robot fish which can be found at the pond on the grounds of Hiroshima Machinery Works. The robot is modeled after a Nishiki koi carp as a form of tribute to Hiroshima Castle (whose nickname Ri-jo means Koi Castle). The 80-cm (31-inch), 12-kg (26-pound) fish has a white body with bright red spots.

Though the tail movement is very smooth and lifelike, the remote-controlled koi is capable of moves that a genuine koi is unable to perform, such as swimming in reverse and rotating in place. Probably in the near future, out in the quiet sea, fisherman will be able to catch this fish for sale. I would be glad to see an automatic robotic fish in my house pond which never need to eat or to be control.
