In 2015 we carried out a questionnaire survey of Internet addiction. A total of 10,596 students took part from junior high school. Analysis of the results revealed that 5.7% of students are at high risk of Internet addiction. We also found that the risk is higher for girls, lower grades and those who use social networking services (7.1%). Also we found that tendency for addiction is strongly related with the use to escape from a depressed mood and stress. There are several types of Internet addiction. These include Internet game addiction, SNS addiction, content addiction, in which users spend long time in contact with content such as videos and gambling-type addiction, in which users become absorbed in Internet auctions and social games. It seems likely that the Japanese cultural climate which places a strong emphasis on conformity puts people at greater risk of SNS addiction than elsewhere. In our 2017 nation-wide survey 20.1% of teenagers are at high risk of Internet addiction. The time Japanese youth spend online is continuing to increase as a result of age lowering for smartphones use. We should develop objective method for detecting addiction.
