Kokugyo

Title given to Koi that won Best in Size at the All Japan Combined Nishikigoi Show. The prize is named the Kokugyo prize. Literally it is the best prize for that section of Koi. Many Koi hobbyists target this prize. The term can also be used to mean Nishikigoi themselves. The same award at the ZNA All Japan Nishikigoi Show is called the Rin'oh prize.
