A story never before told and a memoir to help change our understanding of the world around us, 13-year-old Naoki Higashida's astonishing, empathetic book takes us into the mind of a boy with severe autism. With an introduction by David Mitchell, author of the global phenomenon, Cloud Atlas, and translated by his wife, KA Yoshida.

Naoki Higashida was only a middle-schooler when he began to write The Reason I Jump. Autistic and with very low verbal fluency, Naoki used an alphabet grid to painstakingly spell out his answers to the questions he imagines others most often wonder about him: why do you talk so loud? Is it true you hate being touched? Would you like to be normal? The result is an inspiring, attitude-transforming book that will be embraced by anyone interested in understanding their fellow human beings, and by parents, caregivers, teachers, and friends of autistic children. Naoki examines issues as diverse and complex as self-harm, perceptions of time and beauty, and the challenges of communication, and in doing so, discredits the popular belief that autistic people are anti-social loners who lack empathy.

This book is mesmerizing proof that inside an autistic body is a mind as subtle, curious, and caring as anyone else's.
