On the afternoon of the 18th, a teaser was posted on an online community saying, "Recently, my parents have abandoned me, and my friends have ignored me," and that he will be brandishing a weapon near Yata Station at 6 p.m. on the 23rd.
After other netizens criticized him, the author of this article added, "You're just starting a fire. You didn't even try to comfort me once?"
The creator then captured areas around Noto Station, such as cafes, on a map on a domestic portal site, and drew a picture of the specific area believed to be the location of the crime.
The image was attached. After that, the police who received the report started an investigation, but since it is an anonymous community where IP tracking is difficult, it is said that the identity of the creator has not yet been identified.

The government is also investigating whether the crimes committed by weapon-wielding teasers are the same. Politicians are debating whether to amend the law to punish such crimes as "public intimidation."
The crime of public intimidation is the act of teasing an unspecified number of people online or elsewhere to commit a crime indiscriminately, and carries a sentence of up to five years in prison or 50 million won (approximately 54,000 yen).
The bill includes provisions for severe punishment with a fine of up to 10,000 yen. However, experts point out that in addition to strengthening penalties, it is also necessary to supplement the system.
One expert said, "It is important to simply strengthen punishment, but it is also important to take measures that can prevent recidivism.
There are not enough devices," he said, advising, "We have reached a point where we need a law that allows for probation and follow-up supervision of those who are punished."
