The Fukuoka Bar Association has issued a recommendation to the Fukuoka Police stating that the prohibition of earplugs in police detention facilities constitutes a violation of human rights. This recommendation was made after a male suspect detained at the Kasuya Police Station reported that he was unable to sleep properly due to traffic noise, leading to severe headaches and discomfort. Despite several requests from the suspect to purchase and use earplugs, the police did not grant permission, citing concerns that the use of earplugs might hinder communication and management within the facility.

The police responded to the Bar Association's inquiry by indicating that the fear of not hearing necessary instructions and the potential for concealing or swallowing items were reasons for the ban on earplugs. However, the Bar Association pointed out that while the Ministry of Justice's guidelines for detention centers allow the use of earplugs, there are no clear regulations concerning earplug usage in detention facilities governed by the National Public Safety Commission. They argue that since the suspect is in a pre-trial state, any restrictions on their rights should be limited.

In support of their position, the Bar Association has submitted a request to the Minister of Justice and the Chairman of the National Public Safety Commission urging a review of related regulations. The Fukuoka Police’s detention management section stated that they are currently assessing the matter on a case-by-case basis while aiming to ensure proper treatment of detainees while considering their human rights.
