"Many young people have their own blogs, or they belong to some online social network so it is almost impossible for the police to check every Web site for a possible crime warning," said Tetsuya Shibui, an author who closely follows the relationship between crimes and the use of the Internet.
An attempt to regulate or monitor messages posted on the Web will not put a stop to such crimes, according to Shibui. "I think the fact he posted so many messages should show that he wanted to be heard. He wanted someone to recognize him. Some people need the Internet to have their voices heard."
Society needs to work on creating an environment for people to be heard, said Komiya. "The government needs to create a system where people can get emotional support. Just like we see in the United States and Europe, we should have a mentor system. Many people nowadays cannot even talk to their family members. But if they have a mentor, that may give them peace of mind. Knowing that there is one person in this world who would listen to you can make a huge difference."
