Tanjiro is a young boy of average height with fairly tanned skin and an athletic, muscular physique. He has ruffled, black hair with burgundy tips, combed back to expose his forehead, and wide, dark red eyes with white pupils that appear lighter around the lower section of his irises. He also has a scar on the top left of his forehead, first seen when his mother brought him to watch his father perform the Hinokami Kagura dance. The scar originally looked somewhat like a graze until his fight with the Hand Demon during the Final Selection, after which it develops into a flame-like pattern as his Demon Slayer Mark. It is noted that his hands are visibly rougher for someone his age, as a result of his rigorous training under Sakonji Urokodaki. Tanjiro looks remarkably similar in appearance to his ancestor Sumiyoshi, possessing the same facial structure, eyes, and hairstyle as him, although Sumiyoshi's hair was longer, about shoulder-length and would be tied in a ponytail behind his head.

Tanjiro wears the standard Demon Slayer uniform, a dark-brown gakuran jacket, a white belt, baggy pants that extend into tabi socks, a pair of zōri with red straps, and bands of white cloth wrapped tightly around his calves resembling Kyahan, all beneath his signature checkered haori. He carries a large wooden box on his back (which was a gift to him from Sakonji Urokodaki), where his sister sleeps as they travel during the day.

Tanjiro is very kind by nature and has been described by others as having very gentle eyes and a compassionate persona. He exhibits a great deal of determination and will not give up once he has a goal to achieve; the best example of this being his relentless quest to find a cure for Nezuko. Even though he is relatively strong on his own, Tanjiro isn't opposed to asking others for help when he needs it. He is very protective of his friends and even more so of his younger sister. However, despite his kind and understanding nature, Tanjiro does have a limit to his tolerance and has a distaste for rudeness and cowardice as he easily becomes annoyed by Zenitsu Agatsuma's constant whining, and angered by Inosuke Hashibira's barbaric actions.

From the beginning, Tanjiro was shown to be a prodigious fighter, having a strong natural aptitude for combat, especially in swordsmanship. Tanjiro was already introduced to have superhuman characteristics, like extraordinary senses, a heightened sense of smell, immense willpower and great intellect. His naturally obtained abilities go so far as to allow him to outsmart and catch Giyu Tomioka, one of the most powerful Demon Slayers, off guard and nearly land a fatal blow on him with nothing but his intense emotions.

Just after learning Water Breathing and taking the Final Selection, he was able to easily take down numerous low-level demons without the help of others with his own combat prowess and intellectual abilities allowing Tanjiro to adapt to and defeat his opponents. This was shown when he circumvented the unqiue Blood Demon Arts and fighting styles of decently powerful and skilled demons, such as the Swamp Demon, Susamaru, Yahaba, and Kyogai. Despite still being the lowest rank in the organization, Tanjiro could hold his own against demons who shared the powers of a member of the Twelve Kizuki, the twelve strongest demons in existence and later held his own against an actual member himself, namely Rui, Lower Rank Five. After recalling the Hinokami Kagura, he learned from his father as a child, he almost defeated the Lower Rank demon, a feat which many believed only a Hashira, the strongest swordsmen in the entirety of the Demon Slayer Corps, could pull of.

After mastering Total Concentration: Constant (全ぜん集しゅう中ちゅう・常じょう中ちゅう Zen Shūchū Jōchū?), which further enhanced his physical abilities, Tanjiro was capable of fighting and beheading Lower Rank One, Enmu, one his own, even managing to come up with a solution to the demon's spells in the midst of battle and possessing enough willpower to commit suicide in his dreams in order to wake up. Later, with the help of Nezuko, Inosuke, Zenitsu, and Kyojuro Rengoku, Tanjiro properly decapitated the strongest Lower Rank demon. With the death of Kyojuro at the hands of Upper Rank Three, Akaza, the Flame Hashira's dying words served as a major incentive for Tanjiro to push on in times or crisis and was a key component in his indomitable willpower from then on.

After the battle, Tanjiro could fight on equal ground with Daki, an Upper Rank demon, beings that have lived for over a century and killed numerous Hashira over their lifetimes, and even briefly overpowering her when he was enraged, albeit he ran out of stamina before he could behead her. While injured and slightly fatigued, Tanjiro managed to assist a poisoned Tengen Uzui against Gyutaro and later outsmarted and decapitated him whilst awakening the Demon Slayer Mark momentarily. Thus, Tanjiro became one of the Demon Slayers to ever kill an Upper Rank, a feat that hasn't been accomplished for the last century. Additionally, Mitsuri Kanroji later stated that surviving a battle against an Upper Rank demon equates to around 5 to 10 years of intensive training.

Upon receiving intensive training in the Swordsmith Village, Tanjiro's swordsmanship skills was greatly polished and refined while also awakening the ability to 'smell the future', giving him the movements and reflexes comparable to that of the Hashira. Later, when battling with the weaker clones of Upper Rank Four, Hantengu, one of his clones noted that Tanjiro undergoes explosive growth in the midst of battle, more apparently under ciritical moments. During this same battle, Tanjiro managed to fight off 4 Upper Rank-level demons with the help of Genya Shinazugawa and his sister, and later managed to decapitate Hantengu.

With the training he received during the Hashira Training Arc meant to bolster every Demon Slayer in the organization, Tanjiro's abilities were improved yet again, preparing him for the final confrontation with demon-kind. During the Infinity Castle Arc, Tanjiro's immense growth since the beginning was showcased as he made quick work of numerous demons that were on par with Lower Rank demons, and later was stated to possess the same level of skill as a Hashira by Giyu. His expertise and strength was once again displayed when he fought on even ground with Akaza, the demon that took Kyojuro's life, and later upon awakening the Demon Slayer Mark again and accessing the Transparent World and Selfless State, managed to save Giyu's life and behead Akaza.

After the fight, Tanjiro and Giyu encountered the Demon King himself, Muzan Kibutsuji, and both managed to hold him off despite losing an eye can being severely poisoned by him, almost losing his life as a result. After recovering from the ordeal, Tanjiro was able to fight against Muzan by himself, who had just singlehandedly blizted Giyu, Sanemi, Gyomei, Obanai, Zenitsu, Inosuke, and Kanao. Muzan expressed feelings of unease towards Tanjiro due to the similarities between him and Yoriichi, the strongest Demon Slayer and swordsman to ever exist, showing his immense power. With the help of Obanai, Tanjiro managed to drive the Demon King into the corner and stall until sunrise, putting an end to Muzan once and for all./>
