The Security Police (セキュリティポリス Sekyuritī Porisu), also known as the Security Police Division (警備部警護課 Keibibu Keigoka), is the Japanese close protection unit mandated with the responsibility of protecting domestic and foreign VIPs on Japanese soil and abroad. Its officers are known to wear the SP insignia on their suit lapel, red neckties, and pocket handkerchiefs on their suits. Its structure has been greatly influenced by the United States Secret Service. The SP is under the control of the Tokyo Metropolitan Police Department.
