Ichimai-e

Ichimai-e (single-sheet pictures) refers to individual woodblock prints produced and sold as standalone works, distinguishing them from book illustrations (sashie) and album prints. The term encompasses the vast majority of the prints that collectors think of as "Japanese woodblock prints" — individually published designs by identified artists, sold through established retail networks.

The ichimai-e format became the dominant commercial product of the ukiyo-e industry from the mid-eighteenth century onward. These single sheets could be displayed in the home, collected in portfolios, or simply enjoyed and discarded — they were affordable popular art, not precious objects. The standard oban-format ichimai-e typically sold for the price of a bowl of noodles in Edo-period Japan, making them genuinely mass-market products.

Single-sheet prints could be published individually or as part of a series (such as Hokusai's Thirty-six Views of Mount Fuji), but each sheet was sold separately and designed to work as a self-contained composition. The ichimai-e format continued through the shin-hanga and sosaku-hanga movements and remains the primary format for contemporary Japanese woodblock prints. When people refer to collecting "Japanese prints," they almost always mean ichimai-e.
