Koinobori Sky
An AI lifestyle app for overseas users that matches a described family and space to a real koinobori carp streamer set size, and explains its carp colors and pole accessories.
The Problem With This Niche
Koinobori usually reach people abroad as a single decorative windsock bought for a spring photo, with no sense of the size-grading system retailers use or the meaning behind each carp's color and position on the pole. First-time buyers regularly pick a set that's the wrong size for their space, or never learn that each carp is supposed to represent a specific family member.
Koinobori Sky fills that gap. You describe your children, your mounting space, and your region, and Claude AI, working from documented Kodomo no Hi tradition, matches you to a real set size and explains the meaning of every carp and accessory.
