1.1. What are tatami mats?

What are Tatami mats? Tatami is a type of traditional Japanese mat, which can be folded, and used to cover the floor. In Japanese, “Tatami” () is derived from the verb “Tatamu” which means “to fold”, and is used to refer to thin objects used for lining, spreading, or folding.

Tatami mats made by the Japanese from tightly woven dry straw fibers were first introduced in 712. In the Heian period, wooden floors were very popular, when tatami mats were used as sitting mats to express themselves as an aristocratic class.

In the Muromachi period, with the convenience of this type of mat, the Japanese began to make larger tatami sheets that they then glued together to be able to spread throughout the room. Rooms with tatami floors are called zashiki (座敷) which literally means “room to sit”. The code of conduct when sitting on a tatami mat was also spread from here.

Tatami mats developed widely among all classes starting in the 17th century (Edo period). During this period, a room covered entirely with tatami was considered a typical Japanese-style room, 和室 (washitsu). However, nowadays with the modern rhythm of life, tatami mats have gradually disappeared from modern Japanese homes, but in Japanese culture, tatami mats are still unforgettable memories.

Since the Nara period in the 8th century, tatami mats have been used, originally serving as bedding for aristocrats and the upper class. Around the 16th century, tatami transitioned from being used solely for sleeping and sitting to covering entire room floors.

Tatami Mats For Martial Arts

Tatami mats are best known for their use in Japanese martial arts as flooring. Traditional tatami mats offer a firm yet flexible surface that can handle impacts, making them perfect for judo, karate, and aikido. Stepping onto the tatami mat is viewed as a sacred transition into the martial arts practice area.

In modern times, tatami mats used for martial arts are generally constructed from thick foam, akin to what is used in gymnastics. These mats are designed to replicate the feel and characteristics of traditional tatami, with added durability and flexibility. Although made from foam, they are still called tatami in martial arts and are given the same respect as real tatami mats.

Tatami Mats For Sleeping

Tatami mats offer great benefits for back pain relief, posture improvement, and better blood circulation. Their firm structure aligns the spine, which is especially helpful for back sleepers, and they also assist with regulating body temperature. Being compact and easy to store, tatami mats are a practical space-saving option as they do not need a bed frame.

While Japanese tatami mats are known for their comfort and unique style, they are not without their downsides. Maintenance can be challenging, which is why tatami rooms tend to have very little furniture; these mats are easily damaged by tears, scratches, gouges, etc.

One downside of tatami mats is that they absorb things very well, making stains and marks more common. Dust and moisture can also accumulate, and if not properly managed, mold may develop. Regular cleaning and airing are essential to avoid these issues, though it can be a bit of a hassle.

There are also a few other considerations, including the scent of igusa, which some find pleasant while others may find it overwhelming. Another factor is the high cost of Japanese tatami mats.

Making a simple frame to keep your tatami mats in place is quite easy. We suggest using “quarter round” trim or something similar, which can be found at any wood supply store. Ensure that the trim you choose is no higher than the mats, which are about 2.2 inches thick.

– Low-pile carpets are also a viable option for placing tatami mats, though you may notice some additional softness, which could be fine depending on your intended use. It might be a little more difficult to press the mats tightly together due to the carpet’s depth and flexibility.
