Yutaka Yamamoto is a Japanese animation director and original creator born on September 1, 1974, in Osaka Prefecture. He graduated from the Faculty of Literature at Kyoto University before beginning his career in the animation industry in 1998 when he joined Kyoto Animation. Within the company, he worked on a number of productions in various roles, rising to prominence as the series production director for The Melancholy of Haruhi Suzumiya in 2006, for which he also choreographed the widely recognized ending theme dance. His first full directorial assignment was for the series Lucky Star in 2007, but he was replaced after only four episodes due to performance issues. Following his departure from Kyoto Animation, he founded his own animation studio, Ordet, in 2007.

As an original creator, Yamamoto has developed several anime projects from their initial concept. In 2008, he directed Kannagi: Crazy Shrine Maidens, a collaboration between Ordet and A-1 Pictures. In 2011, he directed Fractale, an original television anime series produced by A-1 Pictures and Ordet. One of his most significant original creations is Wake Up, Girls!, a multimedia franchise that began with a film titled Wake Up, Girls! Seven Idols in 2014, followed by a television series and two additional films, all of which credit Yamamoto as the original creator and director. He also directed the original short film Watashi no Yasashikunai Senpai in 2010.

The anime Twilight, also known as Hakubo, is another original work by Yamamoto. Released in 2019, the film was funded through a crowdfunding campaign on the website Campfire, which successfully raised over 16 million yen against a target of 15 million yen. Yamamoto served as the original story creator, screenwriter, director, and sound editor for the project. The story is set in Iwaki City, Fukushima Prefecture, following the Great East Japan Earthquake, and depicts a romance between two high school students who have been affected by the disaster. Yamamoto has referred to Twilight as the final installment in his Tohoku Trilogy, a set of works set in regions affected by the 2011 Tohoku earthquake and tsunami, following an earlier project set in Iwate Prefecture and the Wake Up, Girls! series set in Miyagi Prefecture. His stated intention to create a story dealing with the aftermath of the natural disaster was reported as early as 2011.

Throughout his career, Yamamoto has also worked on adaptations and other projects in roles such as supervising director for the Black Rock Shooter original video animation in 2010. He has been noted for his directorial style, which emphasizes natural human movement and acting, and his work often features detailed choreography for dance sequences. In 2019, he vowed to stop working on animation following the completion of Twilight, although he later announced plans for a dark fantasy original anime project titled Magical Girls. Yamamoto has also worked as a lyricist for some projects. He left his position as president of Ordet in 2016.
