In Japanese tradition, the koi swimming upstream represents perseverance; koi carp streamers (koinobori) flown on Boys' Day (Tango no Sekku) are documented from the Edo period. The legend of carp ascending waterfalls to become dragons derives from Chinese literature (Shiji and Hou Hanshu). *Philipp von Siebold, Fauna Japonica (1833–1850).

Koi fish are one of the canonical Japanese irezumi designs. The foundational narrative is the Dragon Gate (Longmen) legend: a koi that swims upstream through the Yellow River's Dragon Gate waterfall transforms into a dragon. The tradition descends through Utagawa Kuniyoshi's 1827–30 '108 Heroes of the Suikoden' tattooed-hero woodblock prints. Traditional irezumi convention: koi swimming upstream = struggle-in-progress; koi swimming downstream = goal-achieved or completion. Colors (black kuro, red aka, gold ōgon) carry specific secondary meanings.

Koi fish: perseverance, transformation, the Dragon Gate legend. Upstream = struggle; downstream = completion. Japanese irezumi tradition.
