This rush has a long stem and is suitable for weaving tatami facing. Only three cultivars designated as excellent varieties by Kumamoto Prefecture (Hinomidori, Yuunagi, and Hinoharuka) are allowed to use.
The traditional “mud‐dyeing” process makes the rush good quality with a neat gloss and color tone.
