Tell us how many children you have, their ages, whether you're flying from a balcony or a yard, and your region's wind, and our AI matches you to a real koinobori carp streamer set - from a compact 1.5m balcony pole up to a full 4m+ yagura ground stand - and explains exactly which carp represents which family member and why.
Description
Koinobori - literally "carp streamers" - are fabric windsocks shaped like carp, flown outdoors every spring across Japan in the run-up to Kodomo no Hi (Children's Day), May 5. The custom descends from Tango no Sekku, a Boys' Day festival tracing back over a thousand years, and it carries a specific meaning most people outside Japan never learn: the carp is chosen because of a Chinese legend in which a carp swims up a waterfall against the current and, on reaching the top, transforms into a dragon - a symbol of a child pushing through hardship to succeed. Koinobori Sky turns "I want to fly koinobori" into a real, matched setup. Describe your children - how many, and their birth order - along with whether you're mounting on a balcony railing or in a yard, and your region's typical spring wind, and our AI matches you to a real set defined by the magoi's length in meters, the standard sizing unit retailers use, from a 1.5m balcony-bracket pole up through 2m, 2.5m, 3m, and full 4m-plus sets raised on a ground yagura stand. Every match explains the color order flown on the pole, top to bottom. The magoi, the largest carp, is solid black and represents the father. Below it flies the higoi, red, representing the mother - a pairing that became standard practice only in the 20th century; originally a single black carp was flown alone. Below the higoi fly the kogoi, the children's carp, added one per child in birth order and traditionally colored blue for the first child, then green, purple, or orange for additional children, so a family of three children flies five carp in total. Above the carp themselves, every match also explains the two accessory pieces that complete a traditional set: the fukinagashi, a five-colored windsock streamer flown at the very top that represents the five classical elements (wood, fire, earth, metal, water) and is traditionally believed to ward off evil spirits, and the yaguruma, a spinning arrow-wheel ornament mounted at the peak of the pole. The pole and base assembly itself - a compact veranda bracket for a balcony set, or a full cross-braced ground yagura for a yard set - is matched to your stated mounting location. The Sets tab lets you browse real sizes, colors, and accessory pieces as a standalone reference at any time, even without running a match. Your matches are saved to a personal history so you can find the right set again next spring.

Why This App

Koinobori occasionally reach people abroad as a single decorative windsock hung for a spring photo, with no sense of the sizing system retailers use or the meaning behind each carp's color and position on the pole. Koinobori Sky starts from something any parent can describe in a sentence - how many children they have and where they'll fly the set - and turns it into a real matched size and a real explanation of what magoi, higoi, kogoi, fukinagashi, and yaguruma each represent, turning a decoration into a considered family tradition.
