Fūma Shuriken (風魔手裏剣, Fūma Shuriken) are large, four-bladed projectile weapons possessing pre-eminent sharpness and lethality. This type of shuriken is considered characteristic to the famous Fūma clan, after whom they were named and who possibly developed them. However, their use is not limited to this clan. The most commonly used ones can be collapsed for easy storage, leading to its nickname Shadow Windmill (影風車, Kage Fūsha).

Although a Fūma Shuriken is normally characterised by curved blades, the blades can be of any shape, such as the straight-edged ones which cannot be folded, used by Mizuki and Obito Uchiha. Even the giant square-shaped ones utilised by Toroi are classified as Fūma Shuriken.

As Zabuza Momochi and Obito demonstrated, the shuriken can be used in melee combat by spinning the blade in one's hand to slash and stab the opponent directly. In Sasuke Uchiha's battle with Itachi Uchiha, he showed the ability to rig the four blades to disconnect via pulling a connected wire and have them fire at ninety degrees to one another as a surprise attack, as well as imbuing it with lightning to increase its cutting power.
