Foam Katana: A Guide for Cosplayers and LARPers

Apart from the samurai, several fictional characters from anime and manga popularized the katana sword. So, it is not surprising that a foam katana is one of the most common weapon props seen in cosplay and live-action role-play or LARP today. Knowing the history and information about the samurai sword may help you show your creative side and own your character.

How to Choose the Best Foam Katana?

While it is fun to carry a samurai sword with a carbon steel blade, several pop culture events don’t allow metal and wooden swords, making a foam katana an ideal choice. Still, it is important to opt for a durable and realistic-looking weapon.

Type of Material

Foam swords for cosplay and LARP are constructed from high-density foam which is firm and durable. These swords often come with some structural element, such as a fiberglass or a hard plastic inner core that helps to maintain their shape. For safety reasons, the core rod of LARP swords does not extend to the tip.

Polystyrene foam has a closed-cell structure and comes in several densities. If you want a foam katana for sparring, think of a high-quality polyethylene foam that is shock-absorbing, maintains its shape, and gives more weight. Still, cosplay prop swords are lightweight, so they are not recommended substitutes for martial arts practice swords.

Size and Length

In battles and martial arts, the katana sword usually fits the height of the swordsman. While there is no strict measurement for a cosplay sword, it is ideal to opt for one that replicates the size of a real samurai sword. The katana varies in length, but it usually has a blade length of around 60 centimeters long and never shorter than 40 centimeters long, as this makes it a Japanese blade known as a wakizashi instead.

When it comes to size, practicality is an important factor. Sephiroth in the Final Fantasy VII video game is known for his gigantic katana sword, with an overall length ranging from 180 to 240 centimeters. Hence, cosplayers may downsize the weapon to be more durable and less cumbersome to wear in events.

Appearance

The best cosplay props are realistic and dangerous-looking. The blade of a foam sword is often hand painted to look like real metal. Since the Japanese sword is most recognized for its hamon, you may also see some foam blades that simulate the temperline patterns.

The katana sword is distinguished for its tsuba or sword guard, which often has a rectangular or rounded shape. Some foam katana swords feature realistic-looking tsuba with utilitarian or elaborate cut-out designs while others feature a black handle or tsuka in the traditional diamond pattern wrap. It can also be a good idea to opt for a foam katana that includes a scabbard to complete your samurai attire.

Maintenance

All latex-coated blades need maintenance, such as using a silicone spray to prevent the foam sword from drying out. Apart from storing your foam katana in a cool, dry environment, it should also be kept flat on its pommel, not on its tip.

Facts About the Katana Sword

In Japanese history, the katana served as a mighty sword on the battlefield and in duels. Highly valued and respected by samurais, it remains a significant weapon in traditional martial arts today.

Here are the things you should know about the samurai sword:

The use of the wooden katana in martial arts originated in the Muromachi period.

When the ryu systems of teaching martial arts developed, practitioners used wooden swords called bokken in training to preserve the blades of the samurai sword. Early bokken was made from biwa, which was believed to inflict a wound that would not heal. Today, martial artists rely on red or white Japanese oak on their training swords.

In Japanese history and folklore, a bokken served as a weapon of real combat.

In 1612, swordsman Miyamoto Musashi used a wooden sword, or bokken, carved from a boat oar to defeat his rival Sasaki Kojiro. He was undefeated in reportedly 60 duels and perfected the two-blade fighting technique. Today, his Book of Five Rings is well-known even outside of Japan.

In martial arts, practitioners use a wooden katana called bokuto.

While some may utilize a foam katana as a practice sword, martial artists use wooden swords or bokken. In iaido and aikido, practitioners specifically use the bokuto or wooden katana. It is ideal for training because it mimics the weight and handling of a steel blade. Yet it is non-lethal compared to the real samurai sword.

In kendo, the shinai is the safer alternative than the wooden katana.

In the 16th century, kenjutsu used a wooden sword in training, but it eventually evolved into a sporting competition that makes use of a bamboo sword called shinai. Today, kendo practitioners use the shinai, which consists of bamboo strips bound together, for sparring and competitions.

Some martial artists use a heavier wooden sword called suburito.

A training sword should be balanced, but a heavier sword will help develop muscle strength. Hence, some practitioners who perform sword-swinging exercises opt for suburito, which is longer and thicker than typical wooden katana swords.

Katana Guide for Cosplay and LARP

Dressing up as a samurai or taking the role of a favorite anime character is more fun if one takes the whole thing seriously. Here are some facts about the katana sword that may help you act out your part in the game:

The katana was more efficient for fighting on foot than on horseback.

In Japanese history the katana served as an infantry sword while the tachi was a cavalry sword. Both swords are single-edged and curved, but tachi blades tend to be longer and have more curvature than the katana.

The samurai carried the katana with the cutting edge facing up.

The katana can be distinguished from tachi because the samurai wore the sword with its cutting edge facing up, tucked into the belt. On the other hand, the cavalry wore the tachi facing down, suspended from the belt. Hence, it was easier to use with one hand from horseback.

The wearing of daisho was restricted to the samurai class.

The term daisho means large and small, referring to a sword set of long and short swords. During the Muromachi period, the samurai used the katana on the battlefield, and the wakizashi served as a supplementary weapon. Shorter than the katana, the wakizashi measures about 45 centimeters long.

The samurai also used a tanto dagger for their seppuku ritual.

To avoid being captured after battlefield defeats, the samurai traditionally performed a ritual suicide called seppuku, believed to give them an honorable death. They preferred to use the tanto dagger, usually less than 30 centimeters long.

The samurai katana sword is longer than a ninja sword.

The ninja or shinobi may be known for their shuriken, but they also used a sword called ninjato. Compared to the katana with curved blades, the ninja sword often had shorter straight blades and a much longer tsuka or handle.

The sakabato, or reverse-blade katana, is one of the most popular anime swords.

In manga and anime TV series such as Rurouni Kenshin or Samurai X, characters such as Himura Kenshin wields the reverse-bladed sakabato. He is a former assassin who regrets his past, so he uses a reverse-blade katana to fight his enemies while preserving their lives.

A foam katana is one of the most versatile LARP swords for role-playing.

In Kimetsu no Yaiba, the Demon Slayers use nichirin swords, also referred to as color-changing katanas to kill demons. A foam samurai sword will let you play the part of Tanjiro Kamado, Giyu Tomioka, Shinobu Kocho, and more. In One Piece, pirate hunter Roronoa Zoro also owns katana swords such as the Wado Ichimonji, Sandai Kitetsu, and Shusui.

In the Samurai Museum in Tokyo, visitors can indulge in Japanese-style cosplay.

Apart from exhibits of samurai swords, visitors can also try on samurai cosplay costumes, such as kabuto helmets, armor, katana, and other weapons. Professional actors also perform sword demonstrations, and experts share their insights on Japanese swords.

Conclusion

The samurai sword is one of the best-known swords in history. From manga to anime and video games, it serves as the ultimate weapon of several characters like Himura Kenshin, Roronoa Zoro, and Tanjiro Kamado. It is no surprise a foam katana remains a popular choice of anime fans in cosplay and LARP.
