In Japan, a traditional mat is called a "tatami." It's a rectangular, woven mat made from rice straw or grass, and it's been used for centuries as a floor covering in homes and traditional buildings.
Tatami mats are typically 1.8 meters long and 0.9 meters wide, and they're often placed on a raised platform called a "toban" to create a seamless, flat surface.
The height of a tobana is usually around 15-20 centimeters, allowing for easy walking and movement while maintaining the traditional Japanese aesthetic.
Tatami mats are not only functional but also play a significant role in Japanese interior design, with their subtle colors and textures adding warmth and coziness to a room.

What is a Japanese Mat Called?
A Japanese mat is called a tatami. It's a flooring material developed in Japan, originally used as a rug on wooden floors in the Heian period.
Tatami mats are made of three parts: tatami doko, tatami omote, and tatami beri. The tatami doko is the core of the tatami mat, made from dried straw, polystyrene foam, or tatami board.
Tatami mats have a rich history, dating back almost a thousand years to the Heian Period (794-1185). They've survived through many changes in Japan's history and are still a part of Japanese lifestyle.
Tatami mats are unique to Japan, suited to the country's climate, and are still used in traditional Japanese homes, known as Washitsu. Even with Western interior styles becoming popular, tatami mats remain special to Japanese people.
In Japan, tatami mats are typically laid out with a type of floor mattress called a shikibuton, which is a rectangular, quilted pad that's easy to set up and put away.

Martial Arts

Tatami mats are a crucial part of martial arts flooring, particularly in karate, judo, and aikido.
In these disciplines, stepping onto the tatami mat is considered a sacred entry into the martial arts zone.
Tatami mats used for martial arts are designed to be firm yet yielding, making them ideal for impact.
Modern tatami mats are often made of a thick foam similar to that used for gymnastics.
These foam mats are designed to imitate the texture and properties of traditional tatami mats.
They're more durable and flexible than traditional tatami, but still treated with the same reverence in the martial arts world.
Modern Usage and Benefits
Having some tatami mat flooring is a great option because it creates a calming environment in the home.
Tatami mat flooring is comfortable for sitting or sleeping on, and is a safe, soft floor for children to play on.
You can buy tatami mat flooring that is designed to be installed over hardwood floors, making it simple to transform any room into a tatami mat room.
Tatami mats are used today as wall-to-wall floor coverings, just like a carpet, and are a common feature in traditional Japanese homes.
In modern Japan, it is customary for one room of the house, known as the washitsu, or traditional room, to be the tatami room.
This room tends to have traditional décor and features, such as shoji rice paper doors and decorative things like ikebana flower arrangements.
Tatami rooms signal a sudden change in atmosphere from casual to formal when you enter, and depending on the activity that’s about to take place, your behavior and language become deferential and serious.
Care and Maintenance
Tatami mats require regular cleaning to prevent dirt and liquids from being absorbed into the rush grass material. This is especially important in humid environments where mold can grow if the mats are not cleaned regularly.
The lifespan of a tatami mat is typically around 5 to 6 years, after which it will start to show signs of wear. The color will also fade to a yellowish brown over time.

To clean a tatami mat, use a vacuum with a tatami attachment or a tatami-specific mop, always working in the direction of the rush grass to avoid damage. Manual cleaning with a dry cloth is also a good way to keep them in good shape.
Never wear shoes on a tatami mat, as this can cause damage to the rush grass material. Furniture legs should also be suitable for tatami flooring, with a wide, flat bottom that can displace the weight of the furniture.
Regular cleaning is key to maintaining the health and longevity of a tatami mat.

What Material is a Japanese Mat?
A Japanese mat is made of three parts: tatami doko, tatami omote, and tatami beri.
The tatami doko is the core of the tatami mat, traditionally made by tightening dried straw with threads, but nowadays it's often used polystyrene foam or tatami board.
The tatami omote is a rugged part of the surface woven with rush and shichito, but many rushes are now imported from abroad due to decreasing domestic production.
Tatami mats are soft on the surface and firm inside, with a slight amount of springiness, and are made from rice straw that is layered and sandwiched by an outer layer of woven rush grass (igusa).
They usually have a pretty cloth border edge, the heri, around the tatami, which adds to their unique charm.
Comfort and Home Incorporation
Incorporating a tatami space into your home can add extra Japanese vibes to create a Japandi style.

The dimensions of tatami mats are usually approximately 3 feet by 6 feet, making them a great fit for small spaces. A 12-tatami room would have the rough square footage of about 216 square feet.
Some people find the smell of tatami mats to be divine, evoking memories of playing outside as a child. The scent is often described as a faint grass or hay smell.
The compact design of tatami mats makes them a great choice for small spaces, studio apartments, and tiny bedrooms. They can be easily folded up and put away, freeing up space during the daytime.
In Japan, tatami mats are used as a measurement called jo, where the number of tatami that fit in a room indicates its area. This unique measurement system is a testament to the importance of tatami mats in Japanese culture.
