According to reports, he expressed intentions to confront the Chinese ambassador Wu Jianghao to address perceived harsh remarks made by China about Japan. The Tokyo police confirmed that no injuries occurred during the incident, and a knife was discovered on the embassy grounds, according to SCMP and AA.

Additional police officers have been deployed to enhance security at the embassy following the event, Kihara stated during a press briefing.
