What is a tatami mat and how did it originate?

The tatami mat originated during the Heian Period (794-1185). It was a time when wooden, or sometimes even dirt floors, were common. At first, these mats were luxury items because sitting on them as opposed to sitting on uncomfortable wooden or dirt floors, was strictly reserved for the nobility class. But when the Kamakura Period (1185–1333) came around, the priest class and samurai warriors gained power and these tatami mats became a common feature in their homes too.

Up until this point, tatami mats were for the wealthy, the priest and warrior class, and used to indicate rank during religious and tea ceremonies. But by the Muromachi Period (1336 to 1573), tatami mats started to cover entire rooms and therefore became more common and accessible. However, it wouldn’t be until the late 1600s that tatami mats started to become a normal feature in the homes of commoners.

Today, they can still be found in homes across Japan, various other Japanese places such as ryokans and martial arts studios – although the ones used for martial arts such as Judo and Karate are known as Judo tatami and differ from regular tatami mats because they are covered entirely in polymer as opposed to rush grass since polymer is a far more durable material that can take abuse.

The way tatami mats are made today differs considerably compared to how they were made centuries ago. Before, needless to say, they were made entirely by hand, but today they are made by machine.

A tatami mat is made up of different parts – with each part consisting of a different material.

The top section has always been made from Igusa (rush grass), which is essential for its softness, while the filling used to be compressed rice straw, but it would harden over time and attract bugs, which is why today they use either polystyrene foam or wood chipboards. Today, the bottom parts are typically made from non-woven fabric.

Before, tatami mats didn’t have borders, but today many of them do and these borders are made from kiln-dried pine or fabric such as polyester, hemp, or cotton.


How big is a tatami mat?

Tatami mats come in various sizes and are usually twice as long as they are wide. There is a standard size which is around 910mm x 1820mm, but it’s also important to remember that these standard sizes differ depending on where in Japan you are.

The three different standard tatami sizes in Japan.

Standard size in Tokyo: 880mm x 1.76m.

Standard size in Nagoya: 910mm x 1.82m.

Standard size in Kyoto: 955mm x 1.91m.


The benefits of having a tatami mat

It’s perfect for cold and warm conditions: There is a very good reason why tatami mats have rush grass on the top and it’s not only for its perfect balance of softness and firmness. It also creates insulation so cold or heat from the floor never penetrates the mat. Thus, it stays cool in the summer and warm in the winter.

It’s ideal for dry and humid conditions: During humid conditions, tatami mats absorb humidity and release that same humidity back into the air when the air is dry. So technically, it kind of works as a humidifier and a dehumidifier.

It blocks sound: They are great for wooden floors as they absorb the sound of footsteps.

They’re great for sleeping on: Although Western-style beds have gained popularity in Japan, many Japanese people still sleep on a bare tatami mat without a futon. For a Westerner, doing the same will take some getting used to, and there are several health benefits when doing so.

It’s eco-friendly: High-quality tatami mats made from natural materials, not only last for many years but are also 100% recyclable and can even be used as fertilizer.

Tatami mat care tips

Tatami mats are not exactly cheap, but they have all the hallmarks of Japanese quality and can, therefore, last decades with proper care. Check out these essential tatami mat care tips so that you can get the most out of your investment.

Remove shoes: The Japanese norm of removing one’s shoes before entering a home extends beyond cultural reasons. It’s also in part because walking with shoes or slippers on a tatami mat will eventually ruin the fabric and make it dirty. It is therefore best to walk on it barefoot or while wearing socks.

How to clean: Cleaning your tatami mat the proper way is essential because using the wrong method or cleaning detergent will do far more harm than good. The list of cleaning correctly is rather extensive, but the guys at tatamiroom.jp explain it perfectly.

Do not step on the borders: If your tatami mat has a border, then it’s best not to step on it. Stepping on it for long enough will eventually result in the mat getting twisted out of shape.

Storage: Sometimes you may want to store your tatami mat for a certain period. In such a case, it’s best to store it in a cool dry place. It’s also best to put them inside of a cover. Such covers usually come with your tatami mat upon purchase or can be bought separately.
