Uta ga Chikara (歌がチカラ, Songs Are Strength^?) is Kokia's fourth album, released in July 2004, eight months after her last album, "Remember Me." The album centres on inspirational songs, including the official song for the Japan team at the 2004 Summer Olympics, "Yume ga Chikara."

The song "Utau Hito" was later used as the ending theme song for the animated film Furusato: Japan in 2007. Director Akio Nishizawa felt the song was so fitting for his film, it was as if the song were commissioned specifically for it. The song featured on Kokia's first greatest hits album, Pearl: The Best Collection, as well as the B-side of her 2007 single "Arigatō... (The Pearl Edition)."

The album was preceded by two singles: "So Much Love for You" in April and "Yume ga Chikara" in June. "So Much Love for You" was used as the sole theme song for the variety show , while one of the B-sides on the single "New Season (Yume ni Mukatte Fuku Kaze)" was used in a commercial for the Japan Vocational School Information Research (全国専門学校広報研究会). However, most of the promotional focus went to "Yume ga Chikara." The song was used as the official cheering song for the Japan team at the 2004 Summer Olympics.

The album reached #23 on the Japanese Oricon albums charts, selling 20,000 copies. It is Kokia's second most sold album (behind "Remember Me"), as of 2010.

The album received mostly positive reviews from critics. Tomoyuki Mori praised Kokia for her "pure and beautiful vocal quality," and was positive on the inspirational themes on the album. CDJournal gave the album a star of recommendation. They especially praised "Utau Hito," saying that "(Kokia's) fervent singing from the bottom of her heart" made the reviewer fall in love with the song. Also praised were Kokia's motivational songs "Pinch wa Chance" and "New Season (Yume ni Mukatte Fuku Kaze)," along with the acoustic version of "Yume ga Chikara."
