The highly sought after paper is by the living national treasure Iwano Ichibei and his family workshop in the depths of Echizen, where he has privileged access to the most upstream natural water.

Ideal for demanding printing processes both classical and modern, that require repeated pressings. The paper can maintain precision throughout and absorb ink to render the deepest saturation.

The paper is widely recognized as the ideal paper for woodblock printing, Moku-hanga. The paper inherits the most authentic lineage of the great kozo papers Echizen produced throughout history. The likes of Hokusai and Hiroshige all pressed on these pure kozo papers.

100% Nasu-Daigo Kozo, the highest quality kozo mulberry in Japan.

Iwano Ichibei is currently the only individual in the craft who holds the distinction of cultural heritage status. He is the 9th generation of a family dedicated to the craft. Since his father’s time, the family has specialised in Echizen Hosho, thick pure kozo paper. His father played a central role in surviving the craft when pressure to transition to industrial pulp was more than immense, and paved the way for quality woodblock printing papers. The uncompromising work continues to this day in exactly the same setting.
