“One hundred different carp designs appear on Edo yukata
Swimming in blues: Referred to as the king of freshwater fish, the carp has long been praised as an auspicious creature, often appearing in old axioms such as “a carp climbing up the waterfall to become a dragon,” which signifies success or promotion in Japan. Naturally, the fish has often become a motif for paintings and ornaments as well as designs for katagami patterns.”(http://int.kateigaho.com/spr05/katagami-yukata.html)
