You’ve never read a book like The Reason I Jump . Written by Naoki Higashida, a very smart, very self-aware, and very charming thirteen-year-old boy with autism, it is a one-of-a-kind memoir that demonstrates how an autistic mind thinks, feels, perceives, and responds in ways few of us can imagine. Parents and family members who never thought they could get inside the head of their autistic loved one at last have a way to break through to the curious, subtle, and complex life within.

Using an alphabet grid to painstakingly construct words, sentences, and thoughts that he is unable to speak out loud, Naoki answers even the most delicate questions that people want to know. Questions such as: “Why do people with autism talk so loudly and weirdly?” “Why do you line up your toy cars and blocks?” “Why don’t you make eye contact when you’re talking?” and “What’s the reason you jump?” (Naoki’s answer: “When I’m jumping, it’s as if my feelings are going upward to the sky.”) With disarming honesty and a generous heart, Naoki shares his unique point of view on not only autism but life itself. His insights—into the mystery of words, the wonders of laughter, and the elusiveness of memory—are so startling, so strange, and so powerful that you will never look at the world the same way again.

In his introduction, bestselling novelist David Mitchell writes that Naoki’s words allowed him to feel, for the first time, as if his own autistic child was explaining what was happening in his mind. “It is no exaggeration to say that The Reason I Jump allowed me to round a corner in our relationship.” This translation was a labor of love by David and his wife, KA Yoshida, so they’d be able to share that feeling with friends, the wider autism community, and beyond. Naoki’s book, in its beauty, truthfulness, and simplicity, is a gift to be shared.

Advance praise for The Reason I Jump

“ The Reason I Jump is awise, beautiful, intimate and courageous explanation of autism as it is lived every day by one remarkable boy. Naoki Higashida takes us ‘behind the mirror’—his testimony should be read by parents, teachers, siblings, friends, and anybody who knows and loves an autistic person. I only wish I’d had this book to defend myself when I was Naoki’s age.” —Tim Page, author of Parallel Play and professor of journalism and music at the University of Southern California
