Hirosue Ryoko: Wakasa Katsu on Detention
Hirosue Ryoko’s Case: Detention Decision Awaited After Injury Arrest

Tokyo, April 10, 2025 – Actress Hirosue Ryoko, 44, faces an uncertain future following her arrest on suspicion of causing injury to a nurse at a hospital in Shimada City, Shizuoka prefecture. Wakasa Katsu, a lawyer and former deputy director of the Tokyo District Public Prosecutors’ Office Special Examination Department, discussed the case today during a remote appearance on Nippon Television’s “Facts Live Miyaneya.”
Investigation and Detention Decision
Shizuoka Prefectural Police referred Hirosue to prosecutors on April 9. The Hamamatsu branch of the Shizuoka District Public Prosecutors Office is now tasked with determining whether to request her detention. A decision on detention or release is expected within 24 hours of the prosecutor’s call. Concurrently, authorities searched Hirosue’s Tokyo home today in connection with alleged dangerous driving and related injuries.
Wakasa’s Legal viewpoint
wakasa clarified the distinction between the injury arrest and a separate incident involving a rear-end collision with a large trailer on the Shin-Tomei Expressway. He emphasized that the severity of the nurse’s injuries is a critical factor in the detention decision.
“The key to whether or not detention is pursued solely for the injury charge hinges on the extent of the nurse’s injuries,” Wakasa stated. He elaborated, “If the injury requires approximately three days of treatment, and there is minimal flight risk coupled with solid patient identification, a release is likely. However, an injury requiring one to two weeks of treatment presents a more complex scenario, perhaps leading to a fine. Injuries necessitating around two weeks of treatment could result in detention.”
Prosecutorial Procedures and Possible Outcomes
According to Wakasa,district prosecutors typically seek an expedited detention decision. “in most cases, a detention request is filed on the same day the case is referred to the prosecutor’s office, and the judge renders a decision that day,” he explained. “The fact that the prosecutor’s office did not file a detention request yesterday, and the court has not yet made a decision, suggests uncertainty. It remains unclear whether a detention request will be made, which deviates from the standard procedure.”
Wakasa added, “Given this situation, I personally believe that requesting detention is no longer a viable option.”
Dangerous Driving Allegations
Regarding the allegations of dangerous driving and related injuries that prompted the search of Hirosue’s residence,Wakasa anticipates a thorough investigation. “I expect further investigation to determine whether criminal charges can be substantiated,” he saeid.
