The label "Hajiro" is often used to refer to the whole group of old-type black koi with white patterning. Gets confusing when you are thinking of the specific color/pattern version pictured in the books as Hajiro. I like the specifity of precise usage, but in so many ways these are relics of the past... a time when slight variations of patterning was different enough to lead to a new name and some degree of excitement.
I think your photo is a Ginrin Matsukawabake in a color transition period. But, somebody will call it Ginrin Suminigashi ...just be cute.
