Tate Sumi

Long Sumi. A long Sumi shape that is generally parallel to the dorsal fin of the Koi. Sumi tends to appear in a Kuragake shape and very few Taisho Sanshoku have Tate Sumi. Large Tate Sumi make a strong impact, unlike Tate Hi which appears as a weak pattern. Thin Tate Sumi may be Himo Sumi.
