What are igusa rugs?

An igusa rug is a rug made of "igusa". Igusa is a material used for the surface of tatami mats. It is a material that has been familiar in Japan since ancient times and is indispensable for Japanese people's daily life. An igusa rug is a functional rug that combines the qualities of a tatami mat with those of a rug. They can be laid on flooring or on top of tatami mats.

Role and characteristics of igusa rugs

IGUSA rugs have roles and features that other rugs do not have. The following is a list of four major characteristics of igusa rugs.
  • Clean the air
  • Regulates humidity
  • Reduces the source of odors
  • Excellent heat insulation
Each feature is explained in detail.

Air purification

IGUSA is a material that purifies indoor air. The interior of igusa has a sponge structure that absorbs formaldehyde and carbon dioxide. This purifies indoor air and makes life more comfortable.

Regulates humidity

IGUSA absorbs moisture 2.5 times more than cotton. When humidity is high, it reduces the feeling of dampness, and when humidity is low, it relieves dryness, making it possible to maintain a comfortable level of humidity.

Reduction of odor sources

Igusa reduces odor causing substances. It reduces unpleasant odors such as sweat, smoke, aging, and pet odors, allowing people to live without worrying about odors. The aroma of igusa also has a relaxing effect because of its calming, aromatic properties. Many people may say, "I love the smell of igusa".

Excellent heat retention effect

Although igusa is often thought of as a "summer material" because of its light and comfortable feel, it can be used comfortably all year round because of its heat-insulating properties. In summer, it creates a comfortable and cool space, and in winter, it creates a warm and moist space.

Types of igusa rugs

There are many types of igusa rugs. There are so many different types that it is hard to know which one to buy. For those who are not so sure, here are three types of igusa rugs: "plain," "patterned," and "with backing.


Plain igusa rugs have a simple design with no patterns on the surface. You can enjoy the "goodness of igusa itself" as if it were a tatami mat. Even plain rugs have various textures depending on the place of origin and weaving method. The color and texture of igusa rugs differ from one rug to another, so you can compare them while making your selection.

Rugs with backing

There are different types of igusa rugs not only by their surfaces but also by their backsides. When you flip over an igusa rug, you will find that some rugs have a non-woven backing. The rugs with backing are recommended for flooring. The backing prevents the rug from slipping, so it can be used comfortably without shifting. It is also effective in preventing damage to the floor. There are also igusa rugs that have a cushioning material between the backing and the surface. With igusa rugs with cushioning, they can be used on hard floors without feeling as if they are on tatami mats. It will be as comfortable as if it were on a tatami mat. Note, however, that rugs with backing cannot be turned over. If you want to lay it on a tatami mat, you can use it for a long time if you use the one without backing, which can be turned over when the color fades.

Patterned Rags

There are igusa rugs with patterns on the surface. Beautiful designs are created every day by craftsmen's skills. The designs range from those with natural motifs such as flowers and leaves to those with unique Japanese patterns such as facets and latticework. By using patterns effectively, you can create a room to your taste. A modern patterned igusa rugs will match a room with a modern taste. Ethnic-patterned igusa rugs go well with ethnic style rooms. On the other hand, if you incorporate "Japanese patterns," you can create a "Japanese modern space" in a western style room.

Difference from Japanness Overlay carpet(uwashiki)

Japanness Overlay rugs are similar to igusa rugs. The biggest difference is the size. Japanness Overlay rugs are smaller in size than igusa rugs. Rugs are made smaller because they are placed in a part of the room. Japanness Overlay carpets, on the other hand, are intended to be laid out without gaps, and are available in sizes that match the size of the room, such as 2 or 3 tatami mat size. In addition, many Japanness Overlay carpets can be used on the reverse side, so they can be turned inside out when the surface has deteriorated.

Types and Characteristics of Production Places

Most igusa rugs sold in Japan are made from imported igusa. Most of them are imported from China. The next most common imports are from South Korea and Taiwan. More than 80% of the igusa grown in Japan comes from Kyushu. Cultivation is particularly active in Kumamoto Prefecture. In recent years, igusa is also being grown in Okinawa. The characteristics of igusa differ depending on where it is grown. The following is an explanation of the characteristics of rushes produced in China and Kyushu, by region.

Kyushu rush

The igusa produced in Kyushu is harvested after it has fully grown, making it highly durable. Because it is dried slowly, it is characterized by its durability. It is firm and comfortable to step on. Because of the labor involved, the price is higher than that of Chinese rush grass.

Chinese rush

Chinese igusa is unevenly finished because the thickness of the fibers varies. It has the disadvantage of many cavities in the fibers and deteriorates quickly. The price is lower than that of domestic products.
