Dainichi Collection

Dainichi Koi Farm Collection

Dainichi Koi Farm in Ojiya, Niigata Prefecture, Japan, is widely regarded as one of the finest koi breeding operations in the world. Founded by the Mano family, Dainichi has produced countless Grand Champion winners at the All Japan Koi Show and other prestigious competitions. Play It Koi offers select koi from the Dainichi breeding program — fish that carry bloodlines refined over decades for exceptional skin quality, powerful body conformation, and elegant pattern development that improves with age.

The Dainichi Difference

Dainichi koi are known above all for their extraordinary hada — the luminous, almost translucent skin quality that is the hallmark of world-class Nishikigoi. This skin quality comes from the unique mud ponds of Niigata, where mineral-rich mountain water and cold winters create an environment that no artificial facility can replicate. Dainichi's Kohaku, Sanke, and Showa varieties are especially celebrated, with deep, stable hi (red) that holds its intensity even as fish age and grow. The sumi (black) on Dainichi Showa is renowned for its lacquer-like depth.

Collecting Dainichi Koi

Dainichi koi represent a long-term investment. Many of their fish are selected as tosai (one-year-old) and develop dramatically over the next three to five years. The best Dainichi koi appreciate in both beauty and value as they mature, which is why experienced collectors often purchase younger fish with future potential rather than fully finished adults. For collectors building a show-quality collection, combining Dainichi genetics with fish from Kodama Koi Farm creates an outstanding variety of bloodlines.

Caring for Dainichi Koi

Give these exceptional fish the care they deserve. Quarantine all new arrivals and feed a premium koi food program — Dainichi actually produces their own line of koi food formulated to complement their breeding program.
