The journey of Tanjiro Kamado mastering Sun Breathing is one of the most compelling arcs in modern anime, transforming a humble charcoal seller into the foundation of hope for the Demon Slayer Corps. This specific breathing style, one of the original and most powerful techniques, was lost to time and nearly forgotten before Tanjiro’s emergence. Understanding how did tanjiro learn sun breathing requires tracing his path from a desperate survivor to the inheritor of a legacy, a process defined by resilience, ancestral memory, and sheer willpower.
The Lost Breathing Style and the Kamado Legacy
Sun Breathing, or "Hinokami Kagura," was the first of the Breathing Styles created by the original Demon Slayer, Yoriichi Tsugikuni. However, after a falling out, the technique was sealed away and faded into obscurity, passed down only within the Kamado family as the "Hinokami Kagura" dance performed during the annual Fujikasane Mountain Festival. For generations, the Kamado family treated this ritualistic dance as a cultural tradition rather than a combat technique. Tanjiro’s connection to this legacy was not through formal training but through the muscle memory and spiritual imprint inherited directly from his ancestor, Yoriichi, making his lineage the critical key to his development.
The Catalyst: The Tragedy at Mount Fujikasane
The event that set Tanjiro on this path was the horrific massacre of his family, perpetrated by the demon Muzan Kibutsuji. Witnessing the slaughter of his loved ones, including his father Taneshiro, forced Tanjiro to confront the brutal reality of the demon world. When he attempted to defend his younger sister Nezuko with the fluid movements he knew from the family dance, he instinctively utilized the Sun Breathing forms without even knowing their name. This moment revealed that the dance was not just a ritual but a dormant combat style, activating his latent potential through the trauma of survival.
Formal Training Under Sakonji Urokodaki After the tragedy, Tanjiro’s journey led him to the Water Hashira, Sakonji Urokodaki, who became his mentor. Recognizing the unique nature of Tanjiro’s Hinokami Kagura, Sakonji accepted the role of teacher, viewing the boy as the key to potentially defeating Muzan. Under Sakonji’s rigorous tutelage on Mount Sagiri, Tanjiro learned the formal names, forms, and principles of the Sun Breathing style. He moved from instinctive mimicry of the dance to disciplined execution, learning techniques like "Sunrise Breathing" and the 12 forms that constitute the complete style, bridging the gap between heritage and modernity. Unlocking the Transparent World A pivotal moment in Tanjiro’s mastery occurred during his battle against the Hand Demon, a remnant of the Final Selection test. While fighting for his life, he unlocked the Transparent World, a heightened state of perception that allowed him to see the internal biology of his opponent. This ability is intrinsically linked to the Sun Breathing, as Yoriichi himself was the first to develop this technique. By seeing the demon’s weak points in real-time, Tanjiro was able to execute the forms with lethal precision, effectively merging the ancient dance with a new level of situational awareness that defined his fighting style.

As Tanjiro progressed, he learned the tragic history of Sun Breathing’s decline, largely orchestrated by Yoriichi’s jealous peers who suppressed its teachings. This knowledge added emotional weight to his training, understanding he was not just learning a skill but resurrecting a forgotten art. His ultimate test came in the Infinity Castle against the Upper Rank demon Akaza. Here, Tanjiro didn't just rely on the forms; he adapted them, combining Water Breathing techniques with Sun Breathing fundamentals to create a new form, "Heat Haze," showcasing his evolution from a student of tradition to a master of innovation.
