This rush carpet has a simple, never-boring block pattern. Domestic rush grass (produced in Kyushu) is used. Each strand is thick, with a thick outer skin and fine fibers, making it resilient and durable.

Igusa has a natural purifying effect on the air and regulates humidity. It is also stain resistant, and as it is used, it changes to a golden color, giving it a distinctive taste.

The rush grass is treated with hiba essence. (Antibacterial and deodorizing effect)
