A graffiti that reads "Toilet" was found on a stone pillar at Yasukuni Shrine in Tokyo on June 1.

Tokyo police are investigating the incident as a case of property damage.

Footage of a man who makes gestures that appear to be urinating on the stone pillar and then graffities it with red spray-paint has been posted on Chinese social media.

A Chinese man who claims to have posted the video told Nippon TV that he was the one who wrote the graffiti.

S/ Chinese man / I wrote "Toilet." It means bathroom in Chinese, so before I wrote it, I did what I'm supposed to do in the bathroom. I have not been able to control my anger since I found out that the Japanese government allowed the discharge of contaminated water.

When told that graffitiing is illegal, he said he did it to protest the release of treated water from the Fukushima Daiichi nuclear power plant into the sea that began in August 2023.

When we urged him to turn himself in to the police, he said he does not think he did anything against the law.

The police are trying to track the perpetrator down.

They believe he departed from Japan following the incident.
