A lethal, legendary blade known to kill a hundred in one stroke. Tessaiga.

—Sesshōmaru referring to Tessaiga's power.[4]

Tessaiga (鉄砕牙てっさいが, "Iron-Crushing Fang or Steel-Cleaving Fang"), also spelled Tetsusaiga, is a powerful yōkai sword wielded by the inu-hanyō Inuyasha during the main story, and was originally owned by his father who had instructed Tōtōsai to forge this sword by using one of his own fangs as material for the sword's blade. It was the counterpart of Sesshōmaru's inherited sword, the Tenseiga. Out of the two blades, Tessaiga was "the sword of destruction" with an ability said to "kill a hundred demons in a single stroke", while Tenseiga was "the sword of life" which was said to save one hundred lives with a single strike.

The Tessaiga also seemed to possess a mind of its own, as it has been seen guiding Inuyasha, such as wanting to be drawn or giving him advice in certain situations; this was a trait Tessaiga shared with Sesshōmaru's Tenseiga. It was later revealed that the two swords were originally one blade, but Inuyasha's and Sesshōmaru's father decided to divide the blade into two swords, so that he could give each of his sons one sword with each sword possessing different abilities to teach each of the two sons about certain values, which their father wished for them two to learn about and acknowledge.


The swordsmith Tōtōsai created the Tessaiga from a fang of the inu-daiyōkai, Tōga, the father of Inuyasha and Sesshōmaru for the purpose of protecting his human bride, Izayoi. In its 'docile' form, the sword looked like a regular (and rather battered) katana. When wielded properly, it transformed into a weapon roughly the size of a car bumper that somewhat resembles a falchion or, due to regional and historical context, a dadao sabre. As Tessaiga only transformed if the user cared for humans and had yōki, this means that while humans could never wield it in its true form because they do not possess yōki, it would still however protect a human wielder from deadly yōkai abilities. The Tessaiga had the power to slay 100 demons in one swing by striking the Wind Scar; it also had the ability to absorb the technique or skill of a strong yōkai that was defeated with the sword.

Tōga used the Tessaiga to steal Shishinki's Meidō Zangetsuha technique, but because of the danger the technique bore, the Tenseiga was created to contain it. When Tōga died after he battled with Takemaru as he saved his family: his wife Izayoi and his second son Inuyasha, a barrier was put on Tessaiga to prevent full yōkai who hated humans from being able to use it, and the sword was hidden inside his grave in the world between the living and afterlife. Sesshōmaru searched for the sword some time after his father's death, but had no luck in finding it. Finally, he asked Inuyasha about the Tessaiga's location. After a series of events, both brothers travel to their father's grave to claim the Tessaiga. Sesshōmaru was unable to touch the sword, while Inuyasha was not only able to wield it, but used it to defeat Sesshōmaru. After the battle, Inuyasha became the master of Tessaiga and began to use it to aid him in battle. During a battle with the Thunder Brothers, it was revealed that the sheath can 'summon' the Tessaiga. Tessaiga can also protect its master by putting a barrier around him; however, the barrier the sword produces seems to only work after the attack has hit him.

Hama vs Tessaiga

Tessaiga cut off Kikyō's sacred arrow (manga only).

In the manga, but not in the anime version, Tessaiga can also cut off a Kikyō's sacred arrow with a single slash, proving to be more strong than a miko's spiritual power. The only effect of Kikyō or Kagome's arrows is returning Tessaiga to its normal form piercing the blade, but of course their effect is very limited and never permanent.

Inuyasha learns how to transform Tessaiga and use its Kenatsu quickly enough. He didn't learn to use it's true power to slay 100 yōkai until Sesshōmaru (who had a human arm with a Shikon fragment in it so he could wield Tessaiga) briefly stole the sword and used it himself. He showed the power by summoning 100 demons and slayed them, even to the point of destroying a mountain in one slash. Even after seeing the power, Inuyasha didn't know how to use it, until he accidentally used it to prevent Miroku from being eaten by yōkai when he couldn't use his Wind Tunnel. Naraku blackmailed Sango into stealing the sword for him by threatening Kohaku's life. After she and Inuyasha battled, it was then that Inuyasha was able to retake the Tessaiga back. Inuyasha finally discovered the secret of slaying one hundred demons at once, and learned how to use it during another battle with Sesshōmaru. Inuyasha begun to use the Wind Scar as his signature finishing move afterwards until acquiring Adamant Barrage from the talking corpse of Hōsenki I.

However, in a confrontation with Goshinki, a third incarnation of Naraku, the Tessaiga was broken in half quite easily.[5] Tessaiga breaking reveals that it kept Inuyasha's demon blood under wraps.[6] The sword's creator, Tōtōsai, was able to repair the Tessaiga, but in doing so he used one of Inuyasha's fangs. The result is that Tessaiga now became dependent on the strength of Inuyasha himself, rather than his father's - making the weapon heavier and more difficult for Inuyasha to wield. However, at the same time Tessaiga also became much sharper and sturdier, to the point of being able to match a sword forged from the tusk of Goshinki, the same Oni that originally shattered the sword. After relying on his own strength instead of that of his full demon from, Inuyasha became able to wield the Tessaiga and learned how to use a greater power based from that of the Wind Scar to take out a very powerful enemy; an ultimate ability/technique known as the Backlash Wave, saying that the Wind Scar was merely a trick for novices.

The combined attacks of the Tessaiga and the Tenseiga had succeeded in defeating the Sō'unga, the autonomous demon sword of world conquest, which was stronger than either of them alone.[3]

Four years later, Inuyasha had used the Wind Scar to try and defeat the newly awakened Root-Head but failed. One month later, he had demonstrated Adamant Barrage to the son of the late Hōsenki, who had bestowed such an ability onto him. Some hours later, after his first quarter dog-demon child was born, he had held Tessaiga ready to defend his wife and newborn daughter as his elder half-brother and Kirinmaru where coming closer. Before he could attack, however, he and Tessaiga were sucked into the Black Pearl and trapped in where the tomb of his late dog-demon father was for the next fourteen years.

Gaining New Demonic Attacks and Techniques[]

As Naraku became ever stronger from the Shikon Jewel, Inuyasha began to use Tessaiga's useful power/ability-absorbing ability to further strengthen the sword with new and even stronger- attacks and abilities to help him put an end to Naraku. Seeking a way to break Naraku's demonic energy barrier, Inuyasha went to defeat the barrier-keeper of the bat demon tribe in order to obtain a technique to shatter barriers;[7] instead Inuyasha ended up helping the barrier keeper, Shiori. To thank him, Shiori allowed him to cut her orb- the source of barrier/shield-erecting power - and Tessaiga gained the power and ability to break through barriers.[8]

Subsequently, Tessaiga absorbed Hōsenki I's Adamant Barrage technique, but as with the demonic shield-shattering ability, this attack was gained by Inuyasha doing something to help others. In this case, Inuyasha saved his friends from Naraku's miasma instead of trying to cut Hōsenki I and strengthen the sword. Kongōsōha allowed Tessaiga to cut down Naraku's stronger barrier and cut down enemies strong enough to withstand the Wind Scar.

The next power Tessaiga absorbed was the yōki absorption from the demon sword Dakki. Unlike the previous two abilities, Inuyasha had to actually battle and destroy the sword to acquire the power. Since Dakki could absorb yōki, it nearly took all of the Tessaiga's powers, but Inuyasha used his sword to destroy Dakki and gained the ability to absorb yōki in the form of Dragon-Scaled Tessaiga (Kanji: 竜鱗の鉄砕牙; Hiragana りゅうりんのてっさいが; Hepburn: Ryurin No Tessaiga). However, Inuyasha didn't master the Dragon-Scaled Tessaiga right away unlike the previously acquired powers, as being a hanyō limited the amount of yōki Tessaiga could absorb before the yōki backfired on Inuyasha and injured him. By using Dragon-Scaled Tessaiga to absorb the senki from a Seimeikan sent by Naraku, it purified the yōki it absorbed thereby stopping the regurgitation, but in the manga, he cut Nikosen's Life Force Stalk with the Dragon-Scaled Tessaiga.

By doing this, Sesshōmaru and Tōtōsai told Inuyasha that he did not know the true meaning of Tessaiga and took a shortcut instead of mastering the form. After training, Inuyasha learned to see yōketsu of yōkai; by cutting it with Dragon-Scaled Tessaiga he could destroy the source yōki thereby killing the yōkai.

The sixth and final ability, as well as as its strongest and most devastating ability, Tessaiga regained the Meidō Zangetsuha from the broken Tenseiga. During a battle between Sesshōmaru and Inuyasha, Sesshōmaru willingly broke Tenseiga on Tessaiga to give it the Meidō Zangetsuha technique as their father had intended. The technique allowed the user to send their enemy directly to Hell. In the final battle with Naraku, Inuyasha fully mastered the technique and it changed into an attack that cut an enemy and then sent what it touched directly to Hell, while pulling the remains into the cuts.

Physical Description[]

Tessaiga normal form

Tessaiga's katana form.

Inuyasha and Tessaiga Sword

Tessaiga's fang form.

At first glance when not in use, the Tessaiga appeared to be nothing more than a battered katana with a heavily chipped and rusted blade with the hilt's fabric tearing away. When transformed, the blade turned into an oversized dog's fang, fitting for its name. The cross guard turned into a large patch of fur similar to a dog's also. In the later chapters and episodes, the blade not only became slightly larger, but changed colors and transformed according to the abilities it absorbed. When Tessaiga is let go of, such as being thrown towards an enemy, it can retain its true form for a few seconds before reverting to its normal form.

Powers & Abilities[]

The Tessaiga can absorb the powers and abilities of any material, substance, or form of demonic energy it comes in contact with, making itself more powerful and granting it new abilities in the process.

Katana Form[]

  • Anti-Yōkai Barrier: Tōga placed a barrier on the Tessaiga that would burn pure yōkai that attempt to touch it.[9] After Tōga's death, Tōtōsai (being the sword's creator) is the only living yōkai that could both hold and activate the Tessaiga without harm. Oddly enough, the Kitsune Shippō, who is also a pure yōkai, could hold it without harm, so it may be possible that the barrier does not affect any yōkai that shows kindness for humans or that comes with little to no malicious intent. Humans were capable of holding the Tessaiga in its untransformed katana state, with the sword's barrier protecting them from harm. Due to their hybrid nature, hanyō such as Inuyasha could both hold the Tessaiga and activate its true form if they showed compassion for humans. For unexplained reasons, when Sesshōmaru grabbed Tessaiga with a human hand and on multiple occasions with his right hand, despite being rejected by the barrier, Tessaiga still transformed. This suggests that Tessaiga can be forced to transform if a strong enough yōkai were to touch it, which would explain the need for a barrier because if Tessaiga was capable of remaining untransformed for those it deemed unworthy, there would be no need for a barrier. Although its katana form isn't very useful for attacks, it does have very strong durability, having withstood a clash with Tōkijin, which easily cut apart Hiraikotsu, another weapon forged from a demon's body parts. As hanyō become humans once a month, it could also be argued that since they are considered true humans during that time, the barrier was also intended to protect Inuyasha when he became vulnerable during the night of the new moon. Tessaiga can also use the barrier to prevent Inuyasha from drawing it if Tessaiga feels the need to do so.
  • Tessaiga's Scabbard: Being composed of the wood of Bokusenō, the Tessaiga's scabbard could deflect or resist yōki-based attacks; however, if that force was used continuously, the scabbard would crack and its barrier would fail. It could also summon the Tessaiga, as seen when Inuyasha was trapped inside the flask of a sage. If the scabbard was broken, it could be repaired by leaving it beside a hive of yōkai bees, who would use their beeswax to repair it.

True Form[]

Tessaiga Kenatsu

Tessaiga's Kenatsu.

  • Kenatsu (けんあつ, "Sword-Force, Sword-Pressure"): Like many yōkai swords, Tessaiga can cut opponents without touching them by emitting small concentrated bursts of yōki. This was Inuyasha's main method of combat with the Tessaiga before he learned the Kaze no Kizu, using it to dispatch of weaker yōkai with simple slashes. During the night of the new moon, the Tessaiga can't transform since Inuyasha have turned into human, temporary once a month as a hanyō.

Kaze no Kizu.

  • Wind Scar (かぜきず, Kaze no Kizu, "Scar of the Wind"): The Tessaiga's full-powered kenatsu and signature attack that could, according to legend, slay one hundred yōkai in a single strike. It was activated by sensing the fissure (or "scar") between the clashing yōki of the Tessaiga's wielder and his yōkai opponent and swinging the sword into the fissure, unleashing a massive, destructive wave of yōki. Inuyasha took some time to master this technique, and didn't even know of its strength at first, until Sesshōmaru showed it to him.[1] After his battle with Ryūkotsusei, Inuyasha learned to put his own power into the attack so the scar appeared around Tessaiga's blade and could be triggered instantaneously. Until Inuyasha gained that ability, the Wind Scar was not very useful against Kagura since she can change the yōki winds so they didn't clash and create it. Instead of obliterating the rouge raccoon dog demon Shogen Mamiana, it had left a scar on his forehead.


  • Backlash Wave (爆流破ばくりゅうは, Bakuryūha, "Explosive Stream Blast"): The Tessaiga's ougi (lit. "ultimate technique"). It used the opponent's yōki and unleashed the Kaze no Kizu at the right point. The yōkai's energy would be reflected back with the added power of the Kaze no Kizu. Inuyasha first used the technique to defeat Ryūkotsusei by reflecting his yōki blasts back at him. However, two requirements were needed in order to implement the Bakuryūha. The first was that Inuyasha could only reflect pure energy attacks composed of yōki. The second was that his own yōki had to be at a similar level of his opponent's or the Bakuryūha would not form.
  • Power/Ability Assimilation: Perhaps the Tessaiga's most useful ability is its power to absorb the primary abilities/attacks of any yōkai or yōkai-based artifact that is destroyed by its blade and convert said ability into a cutting nature.
  • Indestructibility: During the battle to destroy the demon sword Dakki, it is revealed by Inuyasha that, though Tessaiga can be badly damaged, the blade cannot break so long as he himself is alive. Tessaiga apparently gained this ability after being reforged with Inuyasha's own fang, as the original blade had been bitten in half by Goshinki.
  • Barrier of Wind: Demonstrated during the fight with Dakki, Tessaiga avoids taking direct blows when it reaches a point where it could be destroyed. It releases wind from any cracks it has, forming a protective shell around the blade and its wielder.

Red Tessaiga[]

Red Tessaiga

Red Tessaiga.

  • Akai Tessaiga (赤い鉄砕牙) also known as Kekkai Yaburi no Akai Tessaiga (結界破りの赤い鉄砕牙, "Red Tessaiga Barrier Shattering"): This technique was obtained from Shiori's orb as a reward for saving her from her grandfather and his bat yōkai. In this state, the blade was able to cut through barriers, allowing Inuyasha to reach his enemies. Though it could cut through Naraku's barrier at one point, it could not following the events of Mount Hakurei. It was also ineffective against spiritual shields, such as Hitomiko's. It is known as the "Barrier-Breaking Red Tessaiga" which is unnamed.

Interestingly, when Sesshōmaru fought Inuyasha when Tenseiga and Tessaiga were about to become a single sword, the Kongōsōha was ineffective against the barrier of Tessaiga's sheath (which Inuyasha used to defend himself) while the Red Tessaiga was able to destroy it. However this was anime-only.

    • Kaze no Kizu Kekkai Yaburi no Akai Tessaiga (結界破りの赤い鉄砕牙かぜきず, Barrier-breaking Wind Scar of the Red Tessaiga, "Scar of the Wind Red Tessaiga Barrier Shattering"): While in this state, Tessaiga can still produce the Wind Scar, but adds the ability to break barriers to the blast. Inuyasha had used it against Naraku and Hakudōshi, failing with both; it only worked once on its own against Naraku.[10][11][12] In movie 2, as Inuyasha was about to attack Kaguya with the Wind Scar two colors red and pink, but it appears to be an illusion.[11]
  • Gateway to the Mirror of Stillness: Since all mortal humans can't reach to the Dream Castle of the Pentacle Mirror and did see it, because they're standing on in it at Lake Motosu which it's like a mirror, and since some of them were protected by the Time Barrier from the Mirror of Stillness, Inuyasha's blade turned to red and hit on the ground as it opens a portal that led to the Dream Castle.[11]

Diamond Tessaiga[]

Diamond Tessaiga.

Adamant Barrage


  • Adamant Barrage (金剛槍破こんごうそうは, Kongōsōha, "Diamond Spear Blast"): This technique was obtained from Hōsenki I after Naraku used a Shikon shard to corrupt him and forced him to fight Inuyasha. When swung, the Tessaiga fired a barrage of diamond shrapnel that could dissolve barriers the Red Tessaiga could not, including Naraku's later barriers. This technique could also be combined with the Kaze no Kizu to enhance its power. Oddly, it had no effect on the barrier of Tessaiga's sheath during the battle that joined Tessaiga and Tenseiga.
  • Adamant Backlash Wave: A technique only seen in "Fire on the Mystic Island" where Inuyasha combined the Backlash Wave's power with the Adamant Barrage. The attack sends out tendrils of adamant, which pin the target in place. Inuyasha would then swing his blade, causing the adamant to shatter and fly at his enemy, releasing the demonic energy within the crystal.

Dragon-Scaled Tessaiga[]

Inuyasha and Dragon Scale Tessaiga

Dragon-Scaled Tessaiga.

  • Yōki Absorption: After breaking the yōkai sword Dakki, Tessaiga gained the ability to absorb an opponent's yōki (demonic energy) directly. Inuyasha, being a hanyō, limited the amount of yōki the sword can absorb before it backfired on the user. After being bathed in Yōreitaisei's senki, the regurgitation stopped. This power also allows Inuyasha to pull demons from possessed victims, which he did during his battle with the cat-demon. Like the demonic barrier-breaking ability, this skill is unnamed.
Magatsuhi's Death

Yōketsu have trapped Magatsuhi.

  • Yōketsu (妖穴, "Vortex of Demonic Energy"): The visual manifestation of demonic energy in the form of a whirlpool that appears behind a yōkai and is visible to just a few. It can banish Magatsuhi from possessing someone's bodies.
    • Yōketsu Cutting: After realizing that the true nature of the Dragon-Scaled Tessaiga was to cut yōki, Inuyasha learned how to see yōketsu (the source of a yōkai's yōki) and used the Dragon-Scaled Tessaiga to cut it, instantly destroying normal yōkai. Beings created of many different yōkai, like Naraku and Mōryōmaru, have several yōketsu, which means cutting them will destroy parts of their body and prevent regeneration of the destroyed parts; however, the Fuyōheki proved to be a nuisance as it hides yōki, preventing Inuyasha from seeing where to strike. Against stronger yōkai, the Dragon-Scaled Tessaiga could cut away portions of its opponent's yōki to weaken their power, which could prove fatal.

When Inuyasha cut his own yōketsu, his full yōkai power was released and the energy flowed back into himself and Tessaiga, which caused his yōketsu to grow until it devoured Sesshōmaru's completed Meidō Zangetsuha.

  • Nikosen's Life-Root Stalk: Inuyasha gains the power after beating the yōkai Nikosen, who was once a hermit and imbued his holy aura in the Life-Root Stalk. After absorbing this power into Tessaiga, Inuyasha gained the power to control the Dragon-Scaled Tessaiga's demonic aura with the holy aura from the Life-Root Stalk. This only occurred in the manga.

Flaming Tessaiga[]

Flaming Tessaiga

The Flaming Tessaiga.

At one point, Inuyasha gained this temporary upgrade after absorbing the conjoined twin yōkai Kinka, thus absorbing his power of fire generation. After using the Flaming Tessaiga in this encounter, it was never seen again. Such an additional combined ability was only in the manga. This was remade with Setsuna's Scourge of Swallows and Cyclone Burst attacks in Episode 10 of the spinoff.

  • Flame/Fire Attack: After absorbing Kinka, Tessaiga absorbed his power of producing and controlling flames of fire.[13]
  • Resonance: After Mōryōmaru absorbs Ginka, each strike from the Flaming Tessaiga resonates with the absorbed Ginka and his lighting, causing Mōryōmaru to be attacked from the inside.[13][14]

Meidō Tessaiga[]

InuYasha Final Act Black Tessaiga

Meidō Tessaiga.

  • Meidō Zangetsuha (めいどうざんげつ, "Dark Path of the Dawn's Moon Wave"): This technique was originally absorbed by Tōga during his battle with Shishinki. Due to its dark nature, it was removed from Tessaiga and sealed within Tenseiga, but after being perfected, it attained when Sesshōmaru's Tenseiga broke on Tessaiga. The original technique manifested as a giant black circle that sent anything within its vicinity directly to the Netherworld. It could also be used as an escape from a Meidō one was already in, though the exit location was not set. Inuyasha also used it to reach both the closed-off path between eras in the Bone-Eater's Well and the Sacred Jewel itself.
    • InuYasha's Meido Zangetsuha

      Inuyasha's fully developed Meidō Zangetsuha.

      Meidō Blades: Once Inuyasha completely mastered the Meidō Tessaiga, the Tessaiga could fire multiple black crescent-shaped portals that not only cut an opponent, but have their remains sucked up into the path. Thus the technique kept its original ability intact while also adding the Tessaiga's cutting nature. It seemed to be stronger than the original Meidō Zangetsuha, as it was able to physically kill Naraku, which was impervious to the original move, but of course not his soul due the jewel corruption.


  • In the English adaptations of InuYasha, Tessaiga was called Tetsusaiga (or Tetsaiga) due to an error in translation in the early days of the manga when the tiny っ (tsu) kana (which indicates a glottal stop, or a doubling of the consonant that follows it) was misread as a full-sized つ (tsu) kana, altering the romanization and pronunciation of the word. Both Tetsusaiga and Tessaiga can come from the kanji; the proper spelling depends on how the name is pronounced. The proper romanization is Tessaiga. By the time Viz, the company that translates the anime and manga, realized the error, it was too late.
  • Throughout the series, the Tessaiga's shape has changed between episodes. In some, it is curved near the end, and in others, it is completely straight.
  • Though it was stated that the Tessaiga will repulse the touch of a demon, Shippō has been seen holding the Tessaiga once without feeling any pain. Tōtōsai was also seen holding Tessaiga, and it even transformed. Given the Tessaiga's disposition towards protecting humanity, it is likely that the barrier is not like a sacred barrier which rejects demonic auras altogether, but rather the ill-will most demons feel towards humans. As Shippō is young, he does not bear ill-will towards humans and therefore, unlike Sesshōmaru or Jaken, is not rejected by Tessaiga. Alternatively, this may be because Shippō was not actually attempting to use the sword. In Tōtōsai's case, the sword not only accepts his touch but also transforms, it is most likely the case that, as he was the original forger of the sword, he has a special connection to it and is able to use it in ways normal demons could not, circumventing its normal restrictions.
  • On another note, in Swords of an Honorable Ruler, Sesshōmaru briefly wielded the Tessaiga and it even transformed, but his hand was badly burned, when Inuyasha was possessed by the Sō'unga. Sesshōmaru also wielded Tessaiga in episode 134 to free Lady Sara from the demons that possessed her, and once again his palm suffered burns. This shows that the barrier on Tessaiga can be forcibly by-passed and used by a full demon if they are strong enough to endure the ensuing pain.
  • The Tessaiga is available as a long sword weapon in the Monster Hunter 3 Tri, however it is exclusive to Japan.
    • Also available in Monster Hunter Portable 3rd only after clearing a download quest and obtaining tickets to create it.
  • Tessaiga, along with Inuyasha, Shippō, Miroku, and Kagome make a cameo appearance in Ranma ½ OVA Episode 13. During one of Akane's nightmares, Tessaiga is seen in its true form, stuck in the floor. Tessaiga is seen behind Inuyasha's and Shippō's dead bodies located on Akane's left.
  • Several of the Tessaiga's named techniques have a "crush" theme naming (with the kanji "破", meaning crush, rip, tear, or (more so) blast), nodding to Tessaiga's translation as the "Iron-Smashing Fang." (The "sai" and "ha" are two different kanji however.) The only exception is the Meidō Zangetsuha, which uses the kanji for "wave" instead of "crush."
  • In Episode 130, a comedic filler episode, Inuyasha humorously told Shippō the real secret to using Tessaiga to its fullest was by making the right onomatopoeia noises when swinging it. Also it would seem he was the only demon to handle Tessaiga without being repelled by it.
  • Although the matter was raised by Inuyasha, as concern for Sesshōmaru, after he gained Meidō Zangetsuha, it wasn't explained nor went into detail if Tessaiga absorbed all of Tenseiga's healing powers as well. Though it is unlikely, as Tenseiga would otherwise be useless and Tōtōsai would not have given Sesshōmaru a powerless sword.
  • Technically and chronologically, Meidō Zangetsuha was the first mentioned power Tessaiga ever absorbed.
  • In 2015, an attempt to forge a replica of the Tessaiga was made by blacksmiths on the YouTube series Man At Arms: Reforged. However, the resulting sword differed from the actual Tessaiga in several respects: the sword was shorter, narrower, and thinner than the actual Tessaiga, and, most notably, the blacksmiths added an original, ornamental design onto the blade itself that was intended to mimic the appearance of the Tessaiga's transformation during the Meidō Zangetsuha technique (i.e. the "Meidō Tessaiga"), a stylized representation which obviously is not present on the physical blade of the Tessaiga in the series.[15]
  • In Hanyō no Yashahime, Tōga was erroneously using Tessaiga 600 years ago while fighting Kirinmaru, and as the two beast kings Tōga and Kirinmaru come together to destroy the Grim Comet 500 years ago, he was erroneously using Meidō Zangetsuha with Tessaiga after Kirinmaru cut the comet first, contradicting the origins of Tessaiga having been forged for the purpose of protecting Izayoi[16][17] and Tenseiga having been created to contain Meidō Zangetsuha.
  • There are only two weapons against whom Tessaiga can't never win: Miroku's Wind Tunnel and Hakushin's spiritual power.
  • As an half-demon just like its owner, Naraku can take Tessaiga without the barrier's effect, but of course not use it, marking the only exception in the series.
  • Kanna and Goshinki were created by Naraku with the only purpose of destroying Tessaiga, both of them with the same full story about their creation and final deaths against it.
