Konishi

Konishi Koi Farm

• Founded during the Taishō era (1912–1926) in North Asa, Hiroshima, Konishi Koi Farm has grown into one of Japan’s most established koi breeders. The current owner is Joji Konishi, the third-generation president of the farm.
• Throughout its history, the farm has introduced numerous Meiri—unique, standout Nishikigoi—garnering multiple champion awards at both national (All Japan Koi Shows) and international exhibitions.
• A core philosophy of the farm: “Nishikigoi must not only be beautiful, but also robust and healthy,” ensuring their koi thrive long-term in hobbyist ponds worldwide.

• Karashigoi (Karashi)

  Developed in-house in the early 2000s, Karashigoi has become Konishi’s most iconic variety. Known for its mustard-gold metallic sheen and large-bodied build, it epitomizes the breeder’s innovative legacy.

  These koi can grow extraordinarily large; in autumn, their natural ponds are harvested (sometimes manually or even using cranes) to handle the “super jumbos.”

• Shusui

  A scaleless (Doitsu) variety featuring a pale, almost sky-blue dorsal streak and red/orange underbelly. Konishi’s Shusui remains one of their standout breeds, including variants like “Konishi Kosui.”

• Kujaku

  Celebrated for its metallic, peacock-like pattern and shimmering shina, Kujaku from Konishi frequently captures top awards—like the 2023 All Japan Koi Show’s Best in Variety for Kujaku and the First Prize (90-bu category).

Beyond their main specialties, Konishi maintains an extensive array of handling breeds, including:

• Gosanke Group:

   

  • Kōhaku (white base with red markings)
  • Taishō Sanshoku (Sanke) (white with red and black)
  • Shōwa Sanshoku (Showa) (black base accented with red and white)

   

• Kawarimono Varieties:

   

  • Goshiki (multi-layered, multi-coloured)
  • Aigoromo (white with bluish-edged scales)
  • Yamabuki Ogon (solid metallic yellow-gold)
  • Ochiba Shigure (soft, autumn leaf-like pattern)
  • Ginrin Kōhaku & Ginrin Sanke
