都道府県公安委員会 (Prefectural Public Safety Commission)
PPSC
Summary
Prefectural Public Safety Commissions (PPSCs) are established in each of Japan's 47 prefectures under Police Act Articles 38–51 (Act No. 162 of 1954). Each commission consists of three members in ordinary prefectures and five in larger urban prefectures (Tokyo, Osaka, etc.), appointed by the prefectural governor with consent of the prefectural assembly. Members must have no prior police or prosecutorial role within five years of appointment. PPSCs supervise prefectural police headquarters, approve senior appointments, review citizen complaints under Article 79, and recommend disciplinary action — but formal discipline of officers below the NPSC-controlled ranks is advisory (the prefectural police chief retains final authority over most officer discipline). PPSCs do not independently investigate use-of-force incidents; complaints are forwarded to internal affairs. Evidence access is restricted to what the prefectural police administratively furnish.
