In order to efficiently erase the graffiti written on the walls of the city, Shibuya Ward in Tokyo has AI learn graffiti data, calculate the cost of erasing, and determine the scope of activities of graffiti artists. We are making an attempt to connect it to specific, and we want to eliminate graffiti and protect the landscape.

Graffiti is prohibited by the Shibuya Ward ordinance, and there are cases where people are accused of damaging property.



However, a survey conducted in Shibuya Ward last year on Takeshita-dori, Center-gai, and between Shibuya and Ebisu on the JR Yamanote Line confirmed graffiti in an area of ​​about 7,000 square meters.



Shibuya Ward has started a project to eliminate graffiti since last year, entrusting the removal of graffiti to external businesses and subsidizing the cost of erasing.



In addition, we are accepting graffiti information on the official LINE account of the ward, and this year we have erased 293 cases and 2459 square meters of graffiti by the end of last month.

In addition, AI is trying to learn graffiti data and proceed with erasing efficiently, AI distinguishes graffiti from the video and calculates the area and cost of erasing, as well as graffiti based on the characteristics of graffiti Attempts have also been made to classify people and identify the scope of their activities.



Tetsuto Sato, director of the environmental policy department of Shibuya Ward, said, "I want to create an atmosphere throughout Shibuya that does not allow graffiti."
