Japanese translation is actually "wow yo", which is the mantra of Naruto's mother for a long time. Naruto Uzumaki inherited Namikaze Minato's hair color and pupil color, Uzumaki Kushina's appearance and personality, and that mantra.
Naruto and Jiu Si Nye will unconsciously blurt out "Falling Horse" when they are excited.
Naruto's name source:
The name Usagi Naruto (ぅずまきナルト) comes from the famous house of ナルト, a Japanese city near the sea. If there is an opportunity, you can also see the vortex on the sea (the famous vortex tide). "ナルト" has another meaning, that is, a common decorative food "Mingmen Juan" placed on the surface in Japanese Lamian Noodles, which is named because it looks like a whirlpool of famous stores.
Because "ぅずまきナルト" has the homonym of "Vortex" and "Mingmen" in Japanese, "Naruto Uzumaki" is translated as "Vortex Mingmen" in Hong Kong and Macao. In the cartoon, Naruto's name comes from the name of the protagonist in Perseverance and Endurance written by Jiraiya. Because the protagonist in the book has many beautiful and uplifting spirits, Naruto's parents hope that Naruto can become such a person who never gives up in the future.
