2025年11月16日，日本東京港區赤坂商圈發生一起嚴重傷人事件。一名四十多歲女性在一棟大樓地下一層的音樂演出現場入口處遭到不明男子持刀襲擊，身受重傷。事發當時，受害女子獨自一人在門前候場，左側腰部約五厘米、右手掌約三厘米遭刺傷，傷勢被判定為重傷，但送醫時意識清醒，目前生命體徵暫時穩定。據她本人表示，與行兇男子素不相識。

警視廳通報，事件發生於上午10時30分左右。一名路人目擊男子作案，描述其戴黑色帽子與白色口罩，身高約180厘米，身穿黑色工裝，手持疑似刀具。作案後，男子迅速跳上共享單車向青山方向逃離，動作迅速且疑似有預謀。警方初步判定嫌疑人仍持凶器在逃，已以殺人未遂罪立案，全力追查其下落。截至目前，嫌疑人的身份及作案動機仍不明，尚未發現與受害者有任何聯繫。

進一步調查顯示，受害者是該大樓地下一層Livehouse的簽約表演者。事發當天，她按照演出安排提前前往場地準備，但到達時店鋪門鎖未開，只能在門口獨自等待，不料遭遇襲擊。店內工作人員在聽到異常聲響後即刻發現受害者並協助報警。原定於當日的兩場演出——下午日場與晚間夜場——因事件已緊急取消，網站尚未公布補場安排。

事件發生地點位於東京核心繁華區，距離赤坂見附地鐵站西南僅約150米，周邊商業設施與人流密集。多名路人目擊事件過程，一名途經男子表示曾聽到地下傳來含糊的痛苦叫喊，並看到一名戴帽男子匆忙逃離；另一名市民目擊嫌疑人騎共享單車快速離開，速度異常，似乎刻意躲避。大樓其他樓層的工作人員也表示事件發生後仍感到恐懼，擔心自身安全。

截至目前，警視廳已在赤坂及周邊青山、六本木等區域加強巡邏，調取事發現場及周邊道路監控影像，重點追蹤嫌疑人逃跑路線，並呼籲市民若發現符合“戴黑帽、穿黑工裝、騎共享單車”特徵的可疑人員或掌握相關線索，及時向赤坂署報告。案件的作案動機及嫌疑人身份仍在進一步調查中，警方正全力展開搜捕行動，以防止事件進一步擴大。

On November 16, 2025, a serious stabbing incident occurred in Tokyo’s Akasaka district, Minato Ward. A woman in her forties was attacked by an unknown male assailant at the entrance of a music venue located on the basement level of a commercial building. At the time, the victim was waiting alone to enter for a performance when she was stabbed in the left side of her waist, sustaining a wound approximately five centimeters long, and in the right palm, with a three-centimeter wound. The injuries were classified as severe, but she remained conscious during transport to the hospital and is currently in stable condition. She stated that she did not know the attacker.

According to the Tokyo Metropolitan Police Department, the incident occurred around 10:30 a.m. Witnesses described the suspect as wearing a black hat and white mask, standing approximately 180 cm tall, dressed in black work clothes, and carrying a knife-like weapon. After the attack, the suspect quickly escaped on a shared bicycle heading toward Aoyama. Police have reason to believe he is still armed and have opened a case for attempted murder, actively searching for his whereabouts. As of now, the suspect’s identity and motive remain unknown, and there is no indication of any prior connection to the victim.

Further investigation revealed that the victim is a contracted performer at the Livehouse in the basement of the building. On the day of the incident, she had arrived early to prepare for her scheduled performance. Finding the venue locked, she waited outside alone and was attacked. A female staff member inside the venue heard unusual noises, discovered the victim, and immediately called the police. Two performances were originally scheduled that day—an afternoon show from 1:00 p.m. to 3:30 p.m. and an evening show from 7:00 p.m. to 10:00 p.m.—but both were canceled due to the incident, and no rescheduling plans have been announced.

The location of the attack is in a bustling central area of Tokyo, approximately 150 meters southwest of Akasaka-mitsuke Station, surrounded by restaurants, office buildings, and commercial facilities with heavy pedestrian traffic. Multiple bystanders witnessed parts of the event. One man passing by recalled hearing muffled cries from the basement and saw a hat-wearing man fleeing in a hurry, while another bystander observed the suspect riding a shared bicycle at an unusually fast pace, seemingly trying to evade detection. Employees working on other floors of the building reported lingering fear and concern for their safety after witnessing emergency vehicles and police arrive at the scene.

As of the latest updates, the Metropolitan Police have intensified patrols in Akasaka and surrounding areas such as Aoyama and Roppongi, reviewed surveillance footage from the scene and nearby streets, and are focusing on tracking the suspect’s escape route. Authorities have also urged the public to report anyone matching the description—black hat, black work clothes, riding a shared bicycle—or any relevant information to the Akasaka Police Station. The motive and identity of the suspect remain under investigation, with law enforcement continuing a full-scale search to prevent further incidents.
