The density of the chakra is so high it becomes visible. It not only raises the power of the weapon, but simultaneously turns oneself into a blade as well. The chakra-enhanced blades are strong and sharp enough to cut through solid rock and iron. The technique works best with elemental chakra, especially with wind-natured chakra which greatly increases the offensive cutting power.
- The Flying Swallow is a shōgi piece used in a large-board variant called taikyoku shōgi, which is possibly the most challenging chess-like game in existence, with over 400 pieces of more than 200 types on either side.
- There may have been a mistake with this techniques classification as the second databook calls it a ninjutsu in its description, but classifies it as a taijutsu.
- In the Naruto: Ultimate Ninja series, Kakashi's midair taijutsu attacks are named "Flying Swallow", "Rising Swallow" and "Falling Swallow", causing naming conflicts in that two different moves would have the same name (though a small amount of other characters have this case, though only with their normal moves). However, Asuma was not playable until Naruto: Ultimate Ninja 3, with Kakashi's "Flying Swallow" being renamed "Flying Sparrow" in the second game. However in Naruto: Ultimate Ninja 3, Asuma's technique was renamed "Flying Sparrow" instead for unknown reasons (only in the English localisations; its Japanese name is still the same) while Kakashi in both Japanese and English keeps the swallow motif for his three moves.
- This also applies to Sasuke, who only in Naruto: Ultimate Ninja Storm via his past-self, has an attack named Swallow Rotating Fire (燕転火, Entenka; possibly picked up from his training with Kakashi).
