PechaKucha or Pecha Kucha (Japanese: ペチャクチャ, IPA: [petɕa ku͍̥tɕa], chit-chat) is a presentation style in which 20 slides are shown for 20 seconds each (6 minutes and 40 seconds in total). The format, which keeps presentations concise and fast-paced, powers multiple-speaker events called PechaKucha Nights (PKNs).
