Overview
- The band says guitarist Yoyoyoshie threw a guitar into the crowd at Umeda Club Quattro on April 9, 2026, and that the instrument struck an audience member.
- The injured person was taken to hospital by ambulance and treated for a forehead laceration that required seven stitches and a cervical sprain.
- Otoboke Beaver issued a public apology on August 11 accepting full responsibility and saying the delay in contacting the injured fan and in public comment worsened the person’s emotional distress.
- The band pledged to work with the injured fan during recovery and said members and staff will take steps to prevent a repeat of the incident at future shows.
- The episode has drawn attention to performer conduct and venue coordination as Otoboke Beaver tours more widely, and it could prompt closer scrutiny of crowd‑interaction practices at high-energy concerts.
