Heizaburo Iwano, the founder of Iwano Heizaburo Seishisho, developed this sturdy Washi (Japanese paper) in the first year of the Showa era (1926), using hemp and kozo as the raw materials for Nihonga (Japanese painting).

Kumohadamashi has been a favorite of great modern Nihonga artists such as Taikan Yokoyama and Seiho Takeuchi, and is also widely used in modern Japanese paintings.

Kumo, means cloud in Japanese. The origin of the name comes from the fact that the fibers are so tangled that the surface of the paper looks like the surface of clouds.

Kumohadamashi has a fairly smooth paper surface, with a firm thickness and flexibility that allows you paint and color easily.


Two types of Kumohadamashi are available, with or without Dosa sizing (technique for preventing color bleeds).
Please choose the one that best suits your needs.
