The term aizuri-e (Japanese: 藍摺り絵 "blue printed picture") usually refers to Japanese woodblock prints that are printed entirely or predominantly in blue. When a second color is used, it is usually red. Even if only a single type of blue ink was used, variations in lightness and darkness (value) could be achieved by superimposing multiple printings of parts of the design or by the application of a gradation of ink to the wooden printing block (bokashi).

The development of aizuri-e was associated with the import of the pigment Prussian blue from Europe in the 1820s.^[1][2] This pigment had a number of advantages over the indigo or dayflower petal dyes that were previously used to create blue. It was more vivid, had greater tonal range and was more resistant to fading.^[3] It proved to be particularly effective in expressing depth and distance, and its popularity may have been a major factor in establishing pure landscape as a new genre of ukiyo-e print.
