Carp that climb the wind.

Designer koinobori, festival river-hangs, and a growth-keepsake carp a year — raised on the early-summer breeze for the children of now. Made by a studio, not a souvenir stand.

01The wind does the work

薫風 is the wind that fills them.

Kunpu — the fragrant early-summer breeze that carries the scent of young leaves — is the moment a koinobori stops being cloth and starts to swim. We design for that moment. A carp climbs upstream against the current; the legend says the one that reaches the top of the waterfall becomes a dragon. That is the wish you hang above a child: not that the wind be gentle, but that they be brave enough for it.

So our streamers are cut to fly taut, not to sag. Ripstop sailcloth, screen-printed by hand in six colourways, balanced to hold their shape in a real gust. Festival-grade, made to be raised every May for twenty.

"One black father, one red mother, and a whole school of children — each a wish for courage, sent up on the wind." — Tango no Sekku, the Boys' Festival, kept since the Edo period

02What we make

Three ways to raise a braver banner.

Atelier koinobori

Hand-cut ripstop carp in six colourways, screen-printed with the geometric scale motif. Sized from desk (40cm) to river (5m). Built to fly taut for two decades.

Festival river-hangs

We rig 50 to 5,000 streamers across a river, street, or courtyard — engineering, install, and take-down handled. The Tatebayashi hang holds the world record; we plan to yours.

50–5,000 STREAMERS · NATIONWIDE INSTALL

Growth keepsakes

One small carp a year, dated and named, from a child's first May to their twentieth. A subscription that becomes a streamer-string of a whole childhood.

03Raised since the Edo period

A festival old enough to be brave about being new.

Koinobori have flown over Japan since the eighteenth century, and became their bright modern selves in the Meiji era. We keep the meaning and redraw the cloth — flat colour, hard edges, a studio's eye — so the wish reads as clearly to a child today as it did two hundred Mays ago.

04The river hang

Five thousand carp over one river.

Every spring from late March to early May, Tatebayashi in Gunma strings roughly five thousand koinobori across the Tsuruuda River. In 2005 it set a Guinness World Record — and later flew 6,340 to mark the height of Tokyo Skytree. We plan, rig, and fly hangs at that scale, and at the scale of one school courtyard.
