On March 15, Japanese voice actor Hiro Shimono took on the role of a one-day chief at the Ikebukuro police station for an event aimed at promoting traffic safety. Dressed in a police uniform, he participated in a parade near JR Ikebukuro Station alongside mounted police, where he urged the public to drive with consideration for others rather than prioritizing their own selfish impulses. Shimono brought personal experience to the event, recalling times when he narrowly escaped traffic accidents and engaged with traffic rules through quizzes with police officers.

The event coincided with an important public announcement regarding a new traffic regulation that would come into effect on April 1, which introduces a penalty ticketing system for bicyclists who commit infractions, including 'distracted driving.' Shimono and the officers present discussed this new initiative, underscoring its significance in promoting safe road behaviors. His participation highlights the intersection of celebrity influence and public safety initiatives, leveraging his popularity to reach a broader audience.

Despite his recent diagnosis of laryngitis, announced just a few days prior, Shimono expressed his dedication to continuing his work as a voice actor and ensuring he does not cause undue concern. Known for his roles in popular anime series such as 'Demon Slayer' and 'My Hero Academia,' he spoke about the challenges of managing his voice while staying engaged with his work, aiming to balance his career and health in the public eye. This event not only showcased the importance of traffic safety but also demonstrated how public figures can positively impact societal issues even when facing personal challenges.
