In Japan, the internet has been blamed for a spate of group suicides which appear to have been arranged in online chat rooms.
Andrew Harding talked to one young man searching for someone to die with.
Naoki Tachiwana opened his apartment door with a surprisingly warm smile, and beckoned us in to a neat living room. His computer was switched on - the screen facing out towards Naoki's eleventh floor balcony, and the night sky above Tokyo's eastern suburbs.
"Last night I was up all night," said Naoki, smiling again, "talking online to this woman who really - I mean really - wants to die. She asked me to do it with her today, but I said I couldn't because I had this television crew coming to see me. So she said we can do it after they've gone."
It had taken days of online research, emails and text messages to bring us here - face to face with a member of Japan's "internet suicide" community.
It is a growing, and morbidly frank underworld of chat rooms and websites with names like "Suicide Club," where thousands of (mainly young) people meet and talk and plan their deaths.
At least 26 people have died in this manner in the past two months.
"There's nothing bad about suicide," said Wataru Tsurumi, author of a graphic, and best-selling handbook on the subject. "We have no religion or laws here in Japan telling us otherwise. As for group suicides - before the internet people would write letters, or make phone calls... it's always been part of our culture."
