The sword Kusanagi is one of the Imperial Regalia of Japan. Its high profile has made it popular, and it appears in various works of fiction. Its appearance frequently signals the nearing of an end of the storyline, but not always. Unlike Excalibur, it is rare for characters to actually use Kusanagi in a combat since it is a ceremonial weapon. Instead, its magical properties are stressed. Because it is a Japanese weapon, it is sometimes misrepresented as a katana, even though the Kusanagi legend predates the katana design by a number of centuries. If archaeological evidence is to be taken into account, then Kusanagi would have been double-edged and much shorter than a katana.
The protagonist of the King of Fighters series, whose story is loosely based on the Yamata no Orochi mythos, is called Kyo Kusanagi, and he is one of the descendants of the three clans responsible to seal Orochi 1800 years before. While his clan guards the namesake sword, the Mirror of Yata is in possession of Chizuru Kagura and the Magatama of Yasakani belongs to the Yagami family (which, currently, seems to be reduced to Iori only, due to the accursed blood pact made by them with Orochi himself, by which clan members possess the powerful Orochi Flames at the cost of their men would die young and women would die when giving birth).
In the popular Japanese manga Naruto, a villain named Orochimaru is able to procure the Kusanagi sword from a snake that comes out of his mouth. This is befitting of him both because it references the Yamata-no-Orochi and because an alternate translation of "Kusanagi-no-Tsurugi" is "Sword of the Snake". The manga depicts the sword as a katana, while the anime shows a Jian.
Also, in Part II of the Naruto manga, Sasuke Uchiha wields what he calls a "Sword of Kusanagi", albeit, a different version or variation to Orochimaru's Sword of Kusanagi, though it does not share any of the traits that Orochimaru's Sword had. Orochimaru's Sword of Kusanagi is a Katana (Jian in the anime), while Sasuke's Sword is a Chokuto.
In Part II of the Naruto manga, Itachi Uchiha, a major supporting character, wields the Totsuka-no-Tsurugi, which is a variation of the Kusanagi. It is an ethereal blade that is kept by his guardian spirit, Susanoo.

In the same game, there is a character named Susano who slays the eight-headed snake Orochi with the help of the protagonist. However, the sword he uses is the wooden sword that he carries around, not the Kusanagi. Also, the sword obtained from the first slaying of Orochi in game is Tsumugari, one of the legendary swords of Japan. The Ama no Murakumo no Tsurugi (known in the English version as Thunder Edge) is acquired after defeating True Orochi, echoing the original legend.

Kusanagi is featured as a key element in some of the stories of the series starting out with Miyamtoto Usagi finding the sword in the seashore.
