Tokyo, Japan – Voice actress and live streamer Mogami Ai was brutally stabbed to death while broadcasting live on the Japanese streaming platform ふわっち (Whowatch) in Shinjuku, Tokyo.

Authorities have arrested a male suspect at the scene, who allegedly carried out the attack while the livestream continued to broadcast to viewers.

According to reports, Mogami was in the midst of a 企画 (planned broadcast) where she attempted to walk around the entire Yamanote Line, a popular train loop in Tokyo.

During the stream, viewers suddenly heard a chilling scream—”Kyaa! Help me!”—which continued for nearly a minute before abruptly stopping.

Shortly after, a bloodied individual appeared on-screen. The attacker, still holding a knife, then turned the smartphone camera toward himself, revealing his face to the livestream audience.

The comment section was immediately flooded with shocked reactions, with many viewers questioning if this was a random attack.

Instead of stopping the broadcast, the suspect continued filming the fallen Mogami as she lay motionless on the ground.

A passerby, witnessing the horrific scene, intervened and shouted, “What are you doing?!” Moments later, police arrived at the scene and confronted the suspect.

“Did you do this?” an officer asked.

“I did it,” the man responded calmly, still holding the weapon.

Police immediately took the suspect into custody, officially declaring him under arrest.

Officers then checked Mogami’s condition and confirmed, “No breathing.”

As a crowd gathered around the scene, their shocked voices could be heard in the background of the livestream, which remained active for a significant amount of time before eventually being cut off.

Authorities have not yet released further details about the suspect’s identity or motive, though initial reports suggest he may have been an anti-fan of Mogami.

Investigations are currently ongoing.
