Pecha Kucha, usually pronounced in three syllables like “pe-chak-cha”, is a presentation format in which content can be easily, efficiently and informally shown, usually at a public event designed for that purpose. Under the format, a presenter shows 20 images for 20 seconds apiece, for a total time of 6 minutes, 40 seconds.
It was devised in 2003 by Astrid Klein and Mark Dytham of Tokyo’s Klein-Dytham Architecture (KDa), who sought to give young designers a venue to meet, network, and show their work and to attract people to their experimental event space in Roppongi. They devised a format that kept presentations very concise in order to encourage audience attention and increase the number of presenters within the course of one night. They took the name Pecha Kucha from a Japanese term for the sound of conversation (“chit-chat”).
Klein and Dytham’s event, called Pecha Kucha Night, has spread virally around the world. More than 170 cities now host such events.
