One of the simplest ways to create a comic is the comic strip, which is usually 3-4 panels long. The Japanese have their version of the comic strip, called ‘yon-koma‘ manga or ‘4-panel’ manga. This kind of short strip is very easy to create, using a formulaic narrative structure called ‘kishotenketsu‘. This 4-step narrative division derives from an old Chinese poetry structure of four-line compositions.
