The Investigating Committee for Preparatory Work for Independence (Indonesian: Badan Penyelidik Usaha-Usaha Persiapan Kemerdekaan, abbreviated as BPUPK; Japanese: 独立準備調査会, Hepburn: Dokuritsu Junbi Chōsakai, Nihon-shiki / Kunrei-shiki: Dokuritu Zyunbi Tyoosa-kai), sometimes referred to, but better known locally, as the Investigating Committee for Preparatory Work for Indonesian Independence (Indonesian: Badan Penyelidik Usaha-Usaha Persiapan Kemerdekaan Indonesia, BPUPKI),^{[note 1]} was an organization set up on 1 March 1945 by the Japanese military authority in Java during the Japanese occupation of the Dutch East Indies as the initial stage of the establishment of independence for the area under the control of the Japanese 16th Army. The BPUPK held two plenary meetings; the first was from 28 May to 1 June 1945 and the second was between 10 and 17 July 1945. A BPUPK was also established in Sumatra.
