It was serialized in Shogakukan's manga magazine Weekly Shōnen Sunday from September 1988 to December 1993, with its chapters collected in 24 tankōbon volumes. The manga has been licensed for English release in North America by Viz Media. The story follows Yaiba Kurogane, a samurai boy raised in the forest by his father who ends up returning to city life in Japan. Yaiba encounters a rival swordsman, Takeshi Onimaru, but when the battle just so happens to end in a stalemate, a humiliated Onimaru is lured into malevolence upon stumbling across a magical katana, culminating in his plans to take over the world with an army of demons. This forces Yaiba and his allies to go on a quest to defeat the newly transformed demon lord, while also encountering several figures from Japanese history and mythology along the way. A 52-episode anime television series adaptation, titled Kenyū Densetsu Yaiba, produced by Pastel, aired on TV Tokyo and Television Hokkaido from April 1993 to April 1994.

In 1993, Yaiba received the 38th Shogakukan Manga Award for the category.

Yaiba Kurogane is an adventurous boy who knows how to be a samurai but not much else. He lives with his father, Kenjuro, in the forest. One day, while Yaiba was eating, a troop of gorillas comes to attack. Yaiba and his father escape and hide inside a box. They do not know, however, that the box is full of pineapples and is going to be transported to the city. Once there, Yaiba discovers that he is a legendary warrior who must fight a demonic-looking high school student named Takeshi Onimaru. The people Yaiba meets on his journey help him grow as a samurai through training and guidance. Despite his skill with a sword, Yaiba is impulsive and often creates conflicts with potential allies, necessitating the intervention of his friends. Together, they embark on various adventures and encounter figures from Japanese history and mythology. Their journey eventually leads them to confront a threat that endangers the entire world.

Gosho Aoyama modeled the character of Yaiba after the protagonist of Ore wa Teppei, which also inspired the author to take up kendo, although he noted Teppei to be a lot smarter than Yaiba.
