Abstract: Japans Stalker Regulation Law was formulated based on the homicide that occurred in 1999. Since the enactment of the Stalker Regulation Law in 2000, every time a new type of stalking incident occurs, it had to be revised. The law has been revised three times in 2013, 2016, and 2021. In the first revision, the behavior of sending e-mail was included in the objects of penalty, and in the second revision, the stalking behavior related to SNS was strengthened. The third revision added punishment for obtaining location information through Global Positioning System without the permission of the other party and installing positioning equipment without the consent of the other party. The specific contents of Japans Stalker Regulation Law and its three revisions, as well as the ways to solve the stalking problem in the form of legislation and official and non-governmental cooperation, has some implications for China.
