At the age of thirteen he wrote The Reason I Jump, which was published in Japan in 2007. Its English translation came out in 2013, and it has now been published in more than thirty languages. Higashida has since published several books in Japan, including children's and picture books, poems, and essays. The subject of an award-winning Japanese television documentary in 2014, he continues to give presentations throughout the country about his experience of autism.
