Vignettes which are mostly unrelated to the main focus of the series are placed throughout each episode, some of them adapted from Helvetica Standard, another manga by Arawi.

Originally, the manga was meant to be a short, stand-alone series which was serialized in Kadokawa Shoten's Shōnen Ace magazine between the May and October 2006 issues.

He stated that "[Nichijou] is that rare cult series that has such high end values to it and so many layers and richness that people will overlook because it's a comedy that I cannot recommend it enough.
