"Energizing Shower" (元気のシャワー, Genki no Shawā) is the first Japanese ending theme of the Yu-Gi-Oh! Duel Monsters anime, performed by Aki Maeda'. It debuted on April 18, 2000, and aired during episodes 1 to 48. It was replaced by "The Afternoon of that Day" in episode 49.
Yu-Gi-Oh! Duel Monsters 20th Remaster features this ending, but the visuals have been changed completely. They are now comprised of various stills from the series in a photo-like styling, with a blurry Millennium Puzzle box in the background.
