Yonkoma manga (4コマ漫画, "four cell manga", or 4-koma for short), a comic-strip format, generally consists of gag comic strips within four panels of equal size ordered from top to bottom. (They also sometimes run right-to-left horizontally or use a hybrid 2x2 style, depending on the layout requirements of the publication in which they appear.) Though the word yonkoma comes from the Japanese, the style also exists outside Japan in other Asian countries as well as in the English-speaking market (particularly in mid-20th century United States strips, where Peanuts popularized the format;[1] most strips there, including the last several years of Peanuts, have since moved to a three-panel format).
