Every May in Japan, colourful koi-nobori climb the sky on long poles — carp-shaped streamers catching the wind, one for each child in the family. A celebration of strength, resilience, and the hope parents carry for their children.

This COOLTRUE t-shirt lifts that tradition off the rooftop. Minimalist, hand-sketched, and unmistakably Japanese.
