Tatami

Tatami are soft mats used in Japan.

They cover the floor in special rooms.

These mats are made of rice straw. They have cloth on the long sides. They are twice as long as they are wide.

Long ago, only rich people used them. Now, many homes have them. Some rooms have just one mat room.

People use them for martial arts too. They use them to train and compete.

They can be laid in a T shape. This is for good luck. Tatami make a room feel special.

Long ago, tatami were a luxury for rich people. In the Heian period, only high nobles used them for seating. Later, the samurai and priests used them in their homes. By the end of the 17th century, common people had them too.

People use tatami for many things. Martial artists use them in a dojo for training. Some people even use them for tameshigiri, which is target test cutting.

There are special rules for laying mats in a room. An auspicious layout is one that brings good luck. In this way, the corners of the mats form a "T" shape. Other layouts make a "+" shape. People used those for sad events like funerals. Now, most people prefer the "T" shape to stay lucky. Different cities also make mats in different sizes. For example, Kyoto mats are a specific size. Nagoya mats are also very common.

Making a tatami mat involves several specific layers. The core is the most important part. Traditionally, people sew together rice straw to make it. Modern mats might use compressed wood or foam. The top is a weave made of rush. This weave sits on a base of hemp or cotton. There are four warps for every weft shed. The long edges are often finished with a pretty cloth called brocade. Some modern mats have no edges at all.

The word tatami comes from a verb meaning to fold or pile. This is because early mats were thin and easy to stack. Long ago, tatami were only for the very wealthy. During the Heian period, nobles used them only for sitting. In the Kamakura period, samurai and priests began using them. By the Muromachi period, mats covered whole rooms. Common people did not get mats until the late 17th century.

Different cities in Japan use different mat sizes. Kyoto mats are 1.82 by 0.91 meters. Nagoya mats are 1.91 by 0.95 meters. Tokyo mats are 1.76 by 0.88 meters. In Japan, people measure rooms by how many mats fit. One unit of area is called a tsubo. A tsubo is the size of two mats placed together. One shaku is about the same as one foot.

There are even rules for how to lay mats. People use different patterns to bring good luck. An auspicious layout is a pattern that brings good fortune. In this layout, the corners of the mats form a "T" shape. An inauspicious layout makes a "+" shape instead. People used that pattern for sad events like funerals. Today, most people choose the "T" shape to stay lucky. This shows how much people value the meaning of their space.

Tatami are traditional Japanese mats used for flooring. They are essential components of a washitsu, or Japanese-style room. These mats serve many purposes beyond simple flooring. Martial artists use them for training in a dojo. They are also used for tameshigiri, which is the art of target test cutting.

The mats are typically twice as long as they are wide. This rectangular shape defines the structure of many traditional Japanese living spaces.

Making a tatami mat requires a specific layered construction. The core, or center, is the foundation of the mat. Traditionally, this core consists of rice straw that has been sewn together. Modern versions may use compressed wood chip boards or extruded polystyrene foam.

Above the core sits a weft-faced weave made of rush. This weave is supported by a warp of hemp or cotton. There are usually four warps per weft shed. To reduce costs, some makers use only two warps per shed. The long sides are often finished with brocade or plain cloth edges.

Tatami sizes vary depending on their specific place of origin. Kyoto tatami measure approximately 1.82 by 0.91 meters. Nagoya tatami, also called chukyo, are 1.91 by 0.95 meters. Tokyo tatami, or edo, are 1.76 by 0.88 meters.

There is also a square format from the Ryūkyū Islands. These square mats do not have borders. Modern designs often use this borderless style for its simplicity. These regional differences exist because traditional Japanese length units varied by location.

In traditional measurements, a tatami is 1 by 0.5 ken. This is also equal to 6 by 3 shaku. One shaku is roughly the same length as one foot. Thickness also varies by type. An edomono mat averages 5 to 6 centimeters thick. A kyomono mat is usually 5 to 6 centimeters thick.

People often use partial mats as well. A half mat is called a han-tatami. A three-quarter mat is called a jo-tatami, often used in tea rooms.

The history of tatami shows a shift from luxury to common use. The name comes from a verb meaning "to fold" or "to pile." This suggests early mats were thin enough to stack. During the Heian period, nobles used mats only for seating. Floors in aristocratic shinden-zukuri residences were mostly wood.

In the Kamakura period, the shoin-zukuri style emerged for samurai and priests. By the Muromachi period, mats began covering entire rooms. Commoners did not have access to tatami until the late 17th century.

Layout rules are very important for the meaning of a room. In the Edo period, arrangements changed based on the occasion. An auspicious layout is the most common modern practice. In this pattern, the junctions of the mats form a "T" shape.

An inauspicious layout creates a grid where junctions form a "+" shape. This pattern was used for funerals to avoid bad luck. Today, most people avoid the "+" pattern because it is associated with misfortune.

Measuring space in Japan often involves the size of the mats. A common unit of area is the tsubo. One tsubo is the area of two tatami mats forming a square. This is formally 1 by 1 ken, or about 3.3 square meters.

In the Nagoya region, common room sizes are measured in mats. A 4-mat room is about 7.6 square meters. An 8-mat room is about 15.2 square meters. These measurements help define the scale of Japanese architecture and interior design.
