July 5, 2022

Investigative Agency for Preparatory Efforts for Independence (Japanese: , Hepburn: Dokuritsu Junbi Chōsa-kai, Nihon-shiki: Dokuritu Zyunbi Tyoosa-kai, abbreviated "BPUPK"), better known as the Investigative Agency for Preparatory Efforts for Independence Indonesia (abbreviated "BPUPKI"), is an agency formed by the government of the occupation of the Japanese army in Java. The Japanese military government, represented by the 16th and 25th Army commands, approved the establishment of the Indonesian Independence Preparatory Research Agency on March 1, 1945. Because these two commands were in charge of Java (including Madura) and Sumatra. The BPUPK was only formed for the two regions, while in Kalimantan and East Indonesia, which were controlled by the Japanese Navy command, no similar agency was formed. April 1945 coincided with Emperor Hirohito's birthday. This agency was formed in an effort to gain support from the Indonesian people by promising that Japan would assist the process of Indonesian independence. BPUPK consists of 67 people chaired by Dr. Kanjeng Raden Tumenggung (K.R.T.) Radjiman Wedyodiningrat with vice chairman Ichibangase Yoshio (Japanese) and Raden Pandji Soeroso. Apart from BPUPK members, an Administrative Body (a kind of secretariat) was formed with 60 members. This Administrative Body is led by Raden Pandji Soeroso with Mr. Abdoel Gafar Pringgodigdo and Masuda Toyohiko (Japanese). The task of the BPUPK itself is to study and investigate matters relating to aspects of politics, economy, governance, and matters needed in the effort to establish an independent Indonesian state. On August 7, 1945, Japan dissolved the BPUPK and then formed the Preparatory Committee for Indonesian Independence (PPKI) or (Japanese: Dokuritsu Junbi Iinkai), with 21 members, in an effort to reflect the representation of the various ethnic groups in the Indies. -The Netherlands, consisting of: 12 people from Java, 3 people from Sumatra, 2 people from Sulawesi, 1 person from Kalimantan, 1 person from Sunda Minor (Nusa Tenggara), 1 person from Maluku, 1 person from ethnic Chinese.


The agency's official name in Indonesian is "Agency for Investigating Efforts to Prepare for Independence", but the more commonly used name is "Badan Investigating Efforts for Independence". In many Indonesian historical sources, this agency is often called the "Badan Investigating Efforts to Prepare for Indonesian Independence" or "BPUPKI", but in fact the original name of this institution does not include "Indonesia". The reason was that this body was formed by the command of the Japanese 16th Army which only had authority in Java. The Japanese 25th Army Command, which had authority in Sumatra, only authorized the establishment of the BPUPK for Sumatra on July 25, 1945. Meanwhile, the areas of Kalimantan and East Indonesia were under the authority of the Japanese kaigun (Navy) and they did not allow the establishment of preparatory institutions for independence.


Background At the end of the Pacific war, Japan's defeat became clear. On September 7, 1944, the Prime Minister of Japan, General Kuniaki Koiso, announced that Indonesia would be liberated someday, after the final victory was achieved in the war that Japan called the "Greater East Asia War". In this way, the Japanese hoped that the Allied troops would be welcomed by the Indonesian people as invaders of their country, so that on March 1, 1945 the leadership of the Japanese military occupation government in Java, General Kumakichi Harada, announced the establishment of a special agency tasked with investigating efforts to prepare for Indonesian independence. , which was called the "Investigating Agency for Preparatory Work for Indonesian Independence" (BPUPK).
