This is of interest to me as a member of my family, here on the U.S. (totally non Japanese) fits the syndrome quite closely. As far as I can tell, a combination of social anxiety, depression, pressure, laziness and lack of pressure (enabling behavior from his parents) has led him to not work in over 20 years and live with his parents, socializing online but showing no interest/ability in socializing with people in person... Or doing any productive work. As time goes on, it becomes harder and harder to join society - my relative now is almost 40 but has very little experience in the 'real' world. He has no experience doing things like buying a car, negotiating a mortgage or lease, applying for a job, working at a job, maintaining a household in general, sustaining or building a mature romantic relationship, or any of the other skills he should have learned in his twenties. It's harder to be a 40 year old 18 year old than an 18 year old one.
