Narita Koi Farms raises and sells Nishikigoi (carp), or so-called the “swimming jewel”, in Komaki-shi, Aichi Prefecture. Narita Koi Farms is a small company with only seven employees, but has a unique and major characteristic. That is, they "polish（care）" the carp. They purchase young carp from farms in Hiroshima and Niigata, and raise them to become beautiful fishes. The two "Koi-Baka", or “carp freaks”, are the ones behind this effort. One of them is Mr. Narita, the president and the one in charge of purchasing and sales. The other one, Mr. Yamamoto, is the managing director and Narita’s right-hand man, who is in charge of the "polishing/caring" work. The competitive exhibition is where people compete the beauty of their carp. Nishikigoi was born in Japan, and therefore the exhibition is known for its strict and high standards.
