On the 14th in Kasumigaseki, Tokyo, an incident occurred in which Takashi Tachibana (57), the leader of the political group "The Party to Protect the People from NHK," was attacked with a bladed weapon, sustaining cuts on his head and neck. The Metropolitan Police Department arrested Shion Miyanishi (30), an unemployed resident of Suginami Ward, Tokyo, on suspicion of attempted murder. Miyanishi reportedly stated, "I intended to kill Mr. Tachibana because he drove other politicians to suicide." He also mentioned that he developed homicidal intent after seeing news reports about the suicide of a former Hyogo Prefectural Assembly member. The attack took place near a demonstration being held in front of the Ministry of Finance, where Tachibana was suddenly assaulted while taking photos with supporters. The police confirmed that there was no prior acquaintance between the two and are conducting a detailed investigation into the circumstances of the incident. In an interview, Tachibana stated, "I am not responsible for the former assembly member's death."

東京・霞が関で14日、政治団体「NHKから国民を守る党」の立花孝志党首（57）が刃物で襲われ、頭や首に切り傷を負う事件が発生した。警視庁は、殺人未遂の疑いで東京都杉並区の無職・宮西詩音容疑者（30）を現行犯逮捕した。宮西容疑者は「立花氏を殺そうと思った。ほかの議員を自殺に追い込んだ人間だからやった」と供述し、兵庫県の元県議会議員の自殺報道を見て殺意を抱いたと話しているという。事件は財務省付近で行われていたデモの近くで発生し、立花氏は支援者との写真撮影中に突然襲われた。警視庁は、2人に面識がなかったことを確認しており、事件の経緯を詳しく捜査している。立花氏は取材に対し「元県議の死は私が原因ではない」と述べた。
