Editor’s note: Hiroki may not have been autistic. He is described in the article as a “hikikomori”, or shut-in, someone who reacts to the stresses of everyday life by withdrawing to their room or their house. This phenomenon, primarily Japanese, is known to be associated with autism, especially mild autism in people who have been trying to function like neurotypicals. However, it also affects people with depression, social anxiety, and other mental illnesses.
