Bongiri

Light second half. Nishikigoi that has little pattern on the second half of the body or has a very light pattern compared to the first half. The Koi would look like it was wearing only a shirt. It is a disadvantage when the Koi is small. But if the Koi is high in quality and grows large it could become an outstanding beauty. There are actually many famous Koi with Bongiri.
