Standard for institutional use tatami: Carefully selected raw materials from Japan are used to produce mats of the finest texture, safety and durability
These mats are hygienic and prevent the occurrence of mites and mold.
The mat covers are compliant with the Food Sanitation Act and deemed safe.
They produce no toxic gases even in the case of when burned.
They can be safely used in nursing environments, with children, the elderly and those suffering from allergies.
They are optimal for highly air tight homes.
Only carefully-selected raw materials sourced in Japan are used to manufacture this product in Japan.
Durability
They have been developed for institutional purposes and are extremely strong, tough and long-lasting.
They are difficult to scuff and can be wiped using a damp cloth, making cleaning easy.
They are resilient against humidity and warping.
They do not fade in the sun, and no color variation will occur when one mat is swapped out for another in the future.
The best form of natural soft rush straw mats is recreated to provide these mats with longevity.
They have 40 times the wear and tear resistance of a natural soft rush straw mat.
They are water repellent, and any spilled drinks or food can be wiped up easily with no stain remaining.
Stylish and comfortable
They have a beautiful appearance and provide an air of luxury.
There is a rich variety of colors that can be matched with Western or Japanese décor.

Despite being thin mats, they offer a surprising amount of cushion.
They are made of materials and structured in a way that’s easy on skin making them comfortable in any season.
They feel good under the feet and to the hands, and are smooth to the touch in summer, but not cold in the winter.
They are thin mats, and don’t require any adjustments in floor height to be installed.
They also allow wheelchair-accessible casing beads to be easily installed.
Rich experience installing over 100 thousand mats annually
