He has Nezuko, so he's coming from this position where he can't just say all demons are absolute evil. The editor commented about Tanjiro, ' is a type of male main character that you don't see much. In the making of the cast, Tanjiro had four supporting characters who would balance each other due to their different skills. In the initial design, Tanjiro did not have a scar or wear earrings, but in the end, they felt these features accentuated the character. However, due to the contrasting aesthetics the manga had, they discarded the drawing and instead drew a similar design with Tanjiro having a serious expression. For the release of the manga's seventh chapter, Gotouge drew a cover of Tanjiro wielding his sword while smiling.

Gotouge has cited issues in the making of the character due to the contrast he has with the dark narrative. Tatsuhiko Katayama, their editor, was worried about the one-shot crusade being too dark for the young demographic and asked Gotouge if they could write another type of the main character who would be 'brighter'.

This has led to the character winning multiple awards with Hanae's performance as him also receiving one. The character has been well received by manga and anime critics due to his caring nature and relationship with his sister while also becoming a strong fighter. The character is primarily voiced by Natsuki Hanae in Japanese and Zach Aguilar in English. His design was influenced by Himura Kenshin from Nobuhiro Watsuki's manga Rurouni Kenshin when deciding how androgynous the character should look.

Gotouge created Tanjiro following a suggestion from their editor of having a bright main character who would stand out in his dark narrative. Besides Ufotable's Demon Slayer: Kimetsu no Yaiba anime adaptation, Tanjiro has also appeared in a light novel that acts as a prequel to the manga. After an encounter with Giyu Tomioka, a demon slayer, Tanjiro is recruited by Giyu to also become a demon slayer to help his sister turn human again and avenge his family. Tanjiro goes on a quest to restore the humanity of his sister, Nezuko, who was turned into a demon after his family was killed by Muzan Kibutsuji following an attack that resulted in the death of his other relatives.
