Fluctuations of character arrangement in laterally written Japanese sentences are investigated by means of their spatial frequency characteristics. In this paper, we choose 3 parameters for the investigation, i.e., character center interval fluctuation in the longitudinal direction, that in the transverse direction and gap fluctuation between characters. In above mentioned fluctuations, there is a remarkable difference between the character center interval fluctuation in the longitudinal direction for handwritten sentences and that for word-processed sentences. The power spectra for handwritten sentences are inversely proportional to their spatial frequencies, while those for word-processed sentences are proportional to them. Then, in order to consider the relationship between the fluctuation and the geometric property of characters, we investigate widths of characters, gaps between them, and simulate power spectra of character center intervals that are made from random numbers of normal distribution of the geometric property. As a result, it is shown that character center interval fluctuations in the longitudinal direction are closely related to standard deviations of character widths.
