The concept of hikikomori was first introduced to the public when a Japanese psychiatrist, Tamaki Saito, published a book in 1998 with the name in its title (30).In his book Social Withdrawal (Shakaiteki Hikikomori), Saito defined hikikomori provisionally as “those who withdraw entirely from society and stay in their own homes for more than six months, with onset usually during the latter half of their twenties, and for whom other psychiatric disorders do not better explain the primary causes of this condition.” Since then, hikikomori has attracted the interest of researchers and a few epidemiological studies have been carried out in Japan.Background: As the number of internet users increases, problems related to internet overuse are becoming more and more serious.Adolescents and youth may be particularly attracted to and preoccupied with various online activities.The number of internet users in Japan has exceeded 100 million and continues to grow.Internet technology has changed our daily lives dramatically.
In recent years, internet access has been changing.
Kimberly Young, an American psychologist, initially proposed provisional diagnostic criteria for subjects with problematic internet use with her naming of “internet addiction” in reference to Diagnostic and Statistical Manual of Mental Disorders (DSM) IV (6) criteria for substance dependence in 1996 (7).
Two years later, Young revised her definition of internet addiction, which made it more similar to an impulse control disorder in DSM-IV (8).
The results from a national survey conducted by MIAC in 2013 also came to a similar conclusion; in that male users preferred playing games on the internet while female users mostly used it for communications with their friends (27).
It is notable that 68.4% of teenagers use SNSs, according to the MIAC survey (1).
