Takako Matsu is a renowned Japanese actress and singer who has also contributed her voice to a select number of anime film roles. Born in Tokyo in 1977, she comes from a family with deep roots in traditional Japanese performing arts. Her career began on the stage and in television dramas in the early 1990s, and she quickly rose to prominence as a leading actress in both film and television. Parallel to her acting career, she has also enjoyed success as a pop singer and composer since her musical debut in 1997.

While Matsu is primarily known for her extensive live-action work, her voice acting roles are notable for their prominence in high-profile animated features. In the 2006 fantasy film Brave Story, she provided the voice for the protagonist, Wataru Mitsuya, a young boy who enters a magical world to change his destiny. This role was a significant undertaking, as she voiced the central character of the adventure.

More than a decade later, she took on another role in a major anime production, playing Nazuna's Mother in the 2017 film Fireworks, Should We See it from the Side or the Bottom?. Directed by Nobuyuki Takeuchi and chief-directed by Akiyuki Shinbo at Studio SHAFT, the film featured Matsu in a supporting role as the mother of the main heroine, Nazuna.

A recurring pattern in Matsu's career is her collaboration with Disney. She is widely recognized for voicing Queen Elsa in the Japanese dubbed versions of the Frozen franchise, including the 2013 original and its 2019 sequel. Her performance of the song Into the Unknown in Japanese was featured on the soundtrack and performed at the 92nd Academy Awards. This work extends to other Disney features, such as the video game Kingdom Hearts III, where she also voiced Elsa.

Matsu's work in anime, though not extensive, demonstrates her ability to take on leading and supporting roles in major animated productions. Her performance in Brave Story as a young boy and her subsequent roles in Fireworks and the Frozen films highlight her versatility and her status as a prominent figure in Japanese entertainment who occasionally lends her talents to animation.
