Set in Taisho-era Japan, this beloved shonen series centers on Tanjirou Kamado, a kindhearted charcoal seller who loses his family to a demon attack and must train as a Demon Slayer to protect his sister Nezuko, the sole survivor, who has been transformed into a demon herself. The story balances genuine emotional warmth with striking action, and its richly detailed world has made it a cultural phenomenon across Japan. Fans visiting Tokyo will find Demon Slayer merchandise, pop-up exhibitions, and themed collaborations throughout the city, particularly in Shibuya and Akihabara.
