KUMAMOTO-RUSH is a high quality rush of three varieties that are designated as superior variety by Kumamoto Prefecture. The color and the gloss of rush are toned by traditional “Dorozome” (mud-dying) method. The rush has long stem and suitable for tatami facing weaving.

Link with the Production Area

The cultivation of three varieties (Hinomidori, Yuunagi, and Hinoharuka) are permitted to only producers in the production area. The Dorozome method (immersing the rush into solution of natural soil immediately after the harvest. It enables to dry evenly, suppress the damage, and tone the gloss and color) has been established as an efficient production technique in the course of the long history of KUMAMOTO-RUSH cultivation.
