OSHIMAYA’s Tri-Fold Tatami Mat is made from natural igusa rush and features three connected mats, each approximately 70 cm square—perfectly sized for flexible use. It folds compactly for easy storage, making it ideal not only for traditional Japanese rooms but also for flooring and modern living spaces. The natural scent and moisture-control properties of igusa create a calming and comfortable atmosphere. With anti-slip backing, it’s designed for safe everyday use. Easy to lay out and comfortable in any season, it brings traditional charm to your home effortlessly.
Unlike standard tatami—which tends to be heavy and fixed in place—this lightweight mat (approx. 2.6 kg per set) can cover the space of three tatami mats in a single layout. Just unfold and place—simple and convenient anytime.

※What is interwoven?
A new manufacturing method that combines the best of both worlds by alternating weaving rush grass and plastic pipes.
In addition to the moisture absorbing effect of rush grass, we have achieved a high deodorizing effect by using resin pipes that have been kneaded with an antibacterial agent.

Product Notes
Product Notes
- Since rush grass is a natural material, it is a little delicate, but in return it has many beneficial properties that are gentle on people.
- Igusa is a natural material with unique properties. To fully utilize the benefits of Igusa, regular cleaning of the room and adequate ventilation are essential.
- The color of the rush grass around the edges may look different from the color of the rush grass in the center. Please note that these color differences are a characteristic of rush grass being a natural material and are not a defect in the product itself.
- Please note that as this is a natural material, there may be slight variations in size.
- Each prevention function is an effect compared to the unprocessed product and does not mean complete prevention.
■ Precautions for use
- After purchasing, please take it out of the nylon bag immediately (some products do not come in a bag). If left sealed, it may grow mold.
- Before use, gently wipe the surface with a dry cloth along the grain. This will remove any surface dust and excess dyeing soil (which is harmless to the human body) and increase the luster of the rush grass.
- Rubbing hard or wiping with water may cause discoloration or mold.
- If you close the room in summer, dust mites and other pests will easily appear. Open the windows occasionally to ventilate the room.
■ When storing
- Igusa products can be used in all seasons, but when storing them, lightly tap them to remove dust, dry them in the shade for about two hours, and then store them in a dark, low-humidity place.
■When cleaning
- Igusa will discolor if exposed to direct sunlight, so by drying it in the shade, you can enjoy its beautiful color for a long time.
- Wrap the okara in a cloth and wipe it along the grain of the rush grass to give it a glossy finish.
- If the stain is minor, we recommend wiping it with vinegar rather than using chemical detergents.
■ If mold grows
- Although the product has been treated with anti-mold coating, mold may grow if the rush grass absorbs excessive moisture due to environmental factors (mold will grow if the moisture content is approximately 15% or more).
- If mold does appear, dry it in the shade for about an hour and then use a brush to remove the mold.
- After that, gently vacuum the area, being careful to ventilate the room so that you don't inhale the mold that you removed.
- If the mold is severe, remove it with bleach and rubbing alcohol. Open the windows to allow for adequate ventilation, and wear gloves when cleaning. Moisten a rag with hot water and a small amount of bleach, wring it out tightly, and then wipe the area.
- After that, soak a clean cloth in alcohol and wipe it off. Alcohol has antibacterial properties and is effective in preventing the growth of mold.
- When drying, make sure to ventilate thoroughly.
■ If it gets dirty
- Even if you do spill water, cleaning it up right away will help remove the stain and minimize damage.
- Unless the stain is dark, no detergent is needed if you soak it up immediately.
- If you spill soy sauce, sprinkle flour or baby powder on the surface and let it absorb the dirt before vacuuming it up. For heavy stains, dissolve a mild detergent in lukewarm water and wipe the area with a tightly wrung out rag, or dab the area lightly with benzine.
- If you have crayon or marker stains, apply cream cleanser to a dry cloth and wipe them off carefully. If you have permanent marker stains, wipe them off with nail polish remover.
Please note that since rush grass is a breathing plant, it will discolor (burn) due to ultraviolet rays, but this does not affect its functionality or quality.

We will only exchange the product for a new one if it is defective upon receipt . Please note that the following points are due to the characteristics of rush products and do not mean the product is defective.
Characteristics of rush products
- Due to the characteristics of natural materials, some of the rush may be cut and sticking out.
- Due to individual differences in rush leaves, partial discoloration or uneven coloring may be observed.
- The color may be white or discolored near the edges and seams, but this is due to the natural properties of the rush grass.
- The natural scent may be strong at times but will fade over time.
■ Examples of initial defects
- If the lining is frayed
- If the edges are not sewn properly (not stitched)
- If there are any large holes or tears

Unique interwoven manufacturing method
This fabric is made by interwoven igusa grass and resin pipes, a method unique to Oshimaya. In addition to the moisture absorbing effect of igusa grass, the resin pipes are kneaded with antibacterial agents, which gives it a deodorizing effect. It is ideal for pet rooms and nursing rooms where odors are a concern.
Resin pipes are used for the collar. There is no need to worry about sunburn or discoloration like with rush grass. The rush grass and resin pipes are woven into a dense weave, which increases the strength of the fabric! It is a durable and long-lasting item that is resistant to scratches from pet claws, etc.
Maintenance
Igusa grass originally contains oil derived from plants,
It has dirt-repelling properties.
If you spill a drink or other liquid, wipe it dry immediately.
