Hosho

Hosho is the premium paper grade most closely associated with fine woodblock printing. Originally produced for official government documents (its name derives from "memorial paper" or "presentation paper"), hosho's consistent quality and smooth surface made it the material of choice for printing the most important and expensive prints.

Made from pure kozo fiber with meticulous attention to uniformity, hosho paper has a slightly glossy surface when properly sized (treated with dosa) that accepts fine detail and produces luminous colors. The paper's uniform density ensures consistent pigment absorption across the entire sheet, which is critical for techniques like bokashi gradation. Variations in paper density would cause uneven color, destroying the smooth transitions that define the technique.

The Echizen region (modern Fukui Prefecture) has been the most celebrated source of hosho paper since the Edo period. Echizen hosho was specified by many publishers for their finest editions, and contemporary printmakers continue to prize it. The difference between a print on premium hosho and one on lesser paper is immediately apparent — colors are more luminous, lines crisper, and gradations smoother. For collectors, the paper quality of a print is one of the indicators used to assess whether an impression is from an early, premium edition or a later, more economical run.
