Behind the Scenes of Dubbing Tanjiro Kamado

At the AnimeJapan 2022, the Demon Slayer voice actors had a chance to exchange with the fans. At this particular stage, Hanae shared some challenging experiences when dubbing Tanjiro.
For example, he felt he would die when working with Tanjiro in Episode 10 of Demon Slayer Season 2.
That episode is when the fight between the Demon Slayer Corps and the tandem of Daki and Gyutaro in The Entertainment District Arc.
This fight was so amazing, with many eye feast scenes. It also had many growl parts and screams. With that said, the voice actors had to work 100% of their power. However, he said it was fun too.
Five Facts You Didn’t Know About Tanjiro
He Has Rough Hands.
After his father passes away, Tanjiro becomes the breadwinner of the Kamado family.
Our boy has had to do everything he could to care for the family.
The Kamado family has a tradition of selling coal. And Tanjiro is also a part of that tradition. He has to cut down the tree, make coal, and move down the town to sell it.
His dad taught him all these things when he was young. And when we meet him at the start of the story, Tanjiro seems familiar with the work. He sells coal and helps his mom and Nezuko care for the family whenever possible.

But as we have learned, he is only 13 years old. So while other 13-year-old boys live a happy life and enjoy their childhood, Tanjiro has to take on a massive responsibility for the family.
After the massacre, he spends two years becoming a Demon Slayer. This is because he trains so hard with the program of Urokodaki.
That’s why the hands of Tanjiro are so rough.
In Episode 7 of Season 1, after killing the Swap demon, Tanjiro talks with Kazumi and tells him not to be anguished. But Kazumi said he did not know anything.
Tanjiro holds his hand to calm him down. Kazumi realizes his hands are rough.
He does not just have rough hands; we can see Tanjiro has:
He Has a High-Level Sense of Smell.
Before becoming a Demon Slayer, Tanjiro already owns an incredible nose.
He can feel and identify things by smelling them. His nose is many times stronger than an average person’s.

It shows right in Episode 1 when Tanjiro goes to the town to sell coal. He helps a man identify the perpetrator who has broken the vase. All he needed was to smell that vase. The people seem to believe in Tanjiro so much that, without hesitation, they all agree with his explanation. This implies Tanjiro often helps them just by smelling something.
After becoming a Demon Slayer, his sense of smell is even stronger. Now he can smell the opening threads of his enemies. He can identify their location by the smell. He even feels the emotions of animals, humans, and demons in a large area.
In Episode 6 of Demon Slayer anime Season 1, Tanjiro uses his nose to find the Swap demon.
Former Water Hashira Urokodaki also has this ability. When he first meets Tanjiro in Episode 2, he says that Tanjiro has the scent of kindness and that Tanjiro is too weak to become a Demon Slayer.
Tanjiro’s Forehead is Deadly.
Did you know Mr. Forehead is the nickname of Tanjiro?
Throughout the series, the most potent weapon that has saved Tanjiro many times is not his blade or Dance of Fire God but his forehead.
The first time he uses this secret technique is in Episode 2 of Season 1, when Tanjiro and Nezuko meet the Head Demon.
The boy uses a headbutt to flip the game when the demon tries to take Tanjiro’s axe.
The second is when he meets Inosuke. He uses this secret technique with Inosuke, making him faint immediately after that.

And when he meets the Hashira team, he does the same thing to Wind Hashira Sanemi and makes him fall to the ground after seeing him hurt Nezuko.
But do you know why his head is tough like that?
The reason is in the final part of Episode 10 of Season 2. This scene explains the origin of his forehead. It’s because of his mom; he got this formidable forehead from his mother.
When Nezuko and Tanjiro were children, his mom used her forehead to gore a wild boar and expel it away.
Tanjiro Didn’t Take All the Credit.
Tanjiro may be the main character of the Demon Slayer series, but until the end of Demon Slayer, he needs help to do everything.
Unlike other anime and manga series, where the main character will always become the strongest and save the world from a deadly threat, Demon Slayer focuses on the friendship between the characters.
Although Tanjiro is getting stronger and stronger until the series’ final battle, he still needs support from other characters like Nezuko, Inosuke, Zenitsu, and the Hashira team. He even dies before the final boss, Muzan, turns into dust.
Another is when Tanjiro fights with Upper Moon 5 Rui. The debut of Tanjiro with Sun Breathing is super impressive, but the one who cuts Rui’s head off is Water Hashira Giyuu. If Giyuu didn’t come on time, Tanjiro would probably end up as nutrients to Rui.
It’s easy to understand because Tanjiro has just been a Demon Slayer for months. He needs time and guidance from others to familiarize himself with the work.
Muzan, King of Demons, is Terrified of Tanjiro.

In the battle with Lower Moon 5-Rui, Tanjiro uses the Dance of Fire God to fight against the Spider Demon. That scene is epic. After that, we know that that dance is another version of Sun Breathing, which almost killed Muzan centuries ago.
Sun Breathing has 13 forms; by repeating 12 forms constantly, the user can unlock the 13th form and reach the highest level of Sun Breathing.
Hundreds of years ago, Muzan met Yoriichi and ran away like a coward from the battle after the legendary swordsman used Sun Breathing.
That’s why Muzan is partly afraid of Tanjiro, or more specifically, Muzan is scared of the technique that Tanjio owns.
