Tokubetsu-keibi-tai (Metropolitan Police Department)

The Emergency Service Unit (特別警備隊, Tokubetsu-keibi-tai) was a rapid reaction force of the Tokyo Metropolitan Police Department (TMPD) in the pre-World War II era.

[2] In 1933, this unit was established in the Police Bureau (警務部, Keimu-bu) for the crowd control, riot control, counter-terrorism, search and rescue, disaster response or other emergency missions.

Acting as a SWAT team of the TMPD, they were equipped with a jō, tantō and FN Model 1910 semi-automatic pistol while ordinary police officers had only a sabre.

[1] During the war, as air raids on Japan intensified and civilian casualties increased, TMPD Emergency Service Unit was enhanced for relief mission and renamed as Security Unit (警備隊, Keibi-tai), and at the same time, it was decided to set up similar units in other prefectures with major cities.

But all these units were inactivated in 1946 as the occupation progressed, but on the same day, the Guard Section (防護課, Bougo-ka) was created for the same role in the TMPD only.
