PechaKucha or Pecha Kucha (Japanese: ペチャクチャ, IPA: [petɕa ku͍̥tɕa], chit-chat) is a presentation methodology in which 20 slides are shown for 20 seconds each (six minutes and 40 seconds in total). The format, which keeps presentations concise and fast-paced, powers multiple-speaker events called PechaKuchaNights (PKNs) or Pecha Kucha Nights.
PechaKucha Night was devised in February 2003 by Astrid Klein and Mark Dytham of Tokyo’s Klein-Dytham Architecture (KDa), as a way to attract people to SuperDeluxe, their experimental event space in Roppongi, and to allow young designers to meet, show their work, and exchange ideas.
In 2004, a few cities in Europe began holding PKNs, the first of several hundred cities that have since launched similar events around the world. As of June 2012, PechaKucha Nights were held in 534 cities worldwide
