Although the majority of such internet-related suicide pacts have occurred in Japan, similar incidents have also been reported from other countries including China, South Korea, Germany, Australia, Norway, the United Kingdom, Canada, the United States, and Sweden.
The first known Internet-related suicide pact occurred in Japan in October 2000, with a later February 2003 incident, involving a young man and two young women, that “became a landmark incident of Internet suicide pacts in Japan due to heavy media coverage”. 
Despite the alarmed response of the media, however, Internet-connected suicide pacts are still relatively rare. Even in Japan, where most of such pacts have occurred, they still represent only 2% of all group suicide-pacts, and less than 0.01% of all suicides combined. However, they do seem to be on the increase in that country: 34 deaths from such pacts occurred in 2003; at least 50 are estimated to have occurred in 2004; and 91 occurred in 2005.  One notable example would be Hiroshi Maeue, who on March 28, 2007, was sentenced to death by hanging, alleged to have murdered three participants in a suicide pact. 
An article published in the British Medical Journal in December 2004, by Dr Sundararajan Rajagopal, Consultant Psychiatrist from St. Thomas’ Hospital in London, highlighted the emergence of the relatively new phenomenon of cybersuicide pacts, addressing it from a psychiatric perspective. Dr Rajagopal commented “The recent suicide pacts in Japan might just be isolated events in a country that has even previously been shown to have the highest rate of suicide pacts. Alternatively, they might herald a new disturbing trend in suicide pacts, with more such incidents, involving strangers meeting over the Internet, becoming increasingly common. If the latter is the case then the epidemiology of suicide pacts is likely to change, with more young people living on their own, who may have committed suicide alone, joining with like-minded suicidal persons to die together”.
 Compared to traditional suicide pacts
An article published by the Canterbury Suicide Project makes some notable comparisons between the nature of “traditional” suicide pacts and more recent Internet-related suicide pacts (or, as described in the article, “cyber-based suicide pacts”). It points out that, traditionally, suicide pacts have been extremely rare; usually involve older individuals (50–60 years old) and very few adolescents; and tend to be between individuals with family or marriage-type relationships and differing, but complementary, psychiatric pathologies. On the other hand, the growing number of Internet-related suicide pacts are almost the exact opposite: they involve young people almost exclusively; tend to be between complete strangers or individuals with platonic friendship-type relationships; and the common characteristic between them would seem to be clinical depression.
The article also points out that the trend of Internet-related suicide pacts is changing the way that mental-health workers need to deal with depressed and/or suicidal youngsters, advising that it is “prudent for clinicians to ask routinely if young people have been accessing Internet sites, obtaining suicide information from such sites, and talking in suicide chat rooms”
