It seems that Hinami was hit by a car in downtown Tokyo around 9 PM on August 15th, and has injuries to her head, hips, and legs.
An acquaintance of hers reported via Twitter that she had been in an argument with her boyfriend, who'd accused her of cheating on him. Allegedly, Hinami was walking in a "dazed, dizzy state" and entered the roadway, where she was struck by a taxi. She was transported to hospital via an ambulance and her injuries are reported to not be life threatening.
