Tokyo Dome City Accident: Woman Dies During Inspection as Police Launch Investigation

Tokyo Dome City amusement park remains closed following the tragic death of a 24-year-old female employee during routine maintenance on April 21, 2026. The incident occurred around 11:50 a.m. At the Tokyo Dome City complex in Bunkyo Ward, Tokyo, when the worker became trapped between a descending seat and a support column on the “Flying Balloon” ride. According to the Tokyo Metropolitan Police Department, the employee was conducting a monthly safety inspection of the attraction alongside colleagues when a seat, which should have been secured at the top of the central pillar, suddenly lowered. She was pinned in the gap between the seat and the column and remained trapped for approximately five hours before being rescued. Despite being rushed to a hospital, she was pronounced dead at 5:51 p.m. The victim has been identified as Uemura Hina, a 24-year-old staff member. She was among six employees performing the inspection at the time of the accident. The Flying Balloon ride lifts riders up to 10 meters in the air while rotating, with seats that move vertically and horizontally. Tokyo Dome, the facility’s operator, confirmed the ride involved in the incident and stated that investigations are underway to determine the cause of the unexpected seat descent. Authorities are examining whether proper safety protocols were followed and if any mechanical failure contributed to the tragedy. In response to the accident, Tokyo Dome City announced the suspension of all operations on April 22, 2026, marking the second consecutive day the entertainment complex has remained closed. Officials have not yet announced when the park might reopen, pending the outcome of the ongoing police inquiry. This incident adds to a pattern of safety concerns at the venue, drawing comparisons to a roller coaster derailment that occurred 15 years prior. While Tokyo Dome City had previously pledged to prevent recurrence after that earlier event, investigators are now reviewing whether lessons from the past were adequately implemented. As of now, no official statement has been released regarding potential changes to inspection procedures or ride maintenance schedules. The focus remains on understanding how a routine safety check resulted in a fatal workplace accident at one of Tokyo’s most popular family destinations.
