Japanese carp tattoo: meaning of koi
The Japanese carp, whose meaning in tattoos is perseverance and overcoming, comes from a legend: a koi swam against the current up a waterfall at the Dragon Gate and became a dragon. Hence the composition rule: a carp swimming upward is read as struggle and the path to a goal, while swimming downward means something already achieved and accepted.

Koi adorn temple ponds and yakuza backs for one reason: this fish swims against the current. Let's break down the legend, the direction of movement, and the colors, each of which changes the interpretation.
Where the meaning of the koi carp comes from
The Chinese legend of the Dragon Gate (龍門) tells that carp swam up a river, and the one that managed to climb the waterfall turned into a dragon. Japan adopted the story as a metaphor for perseverance that is rewarded.
