The children’s novel “I’ve Found My Color!”, currently on sale from Kodansha Ltd., has become a hot topic, with the total number of copies of the print edition exceeding 80,000. “I’ve Found My Color!” ” was also selected as a required reading for the 71st National Youth Book Report Contest (upper elementary school division) and as a recommended reading for the 2024 Saitama Winter Break. In addition, it was included in the 2024 junior high school entrance exams at six schools: Atsumi Gakuen 1, Otsuma 3, Kamakura Jogakuin 1, Gyosei 1, Nihon University A1, and Yokohama Futaba 1. With its easy-to-read writing style and structure, this book has been chosen as the subject of many upper elementary school students’ book reports. This is the key point! Color vision deficiency affects a large number of people, with 1 in 20 boys and 1 in 500 girls, but there are not many children’s novels that tackle this topic head-on. This book is an ambitious work written by a former teacher, who interviewed many people, including those affected, those involved, and ophthalmologists. We interviewed many people involved (those affected, those close to them such as their parents, experts, and doctors) in pursuit of realism, and received a flood of empathy from those affected, saying, “I know, I know!”
