J-pop singer-songwriter Kaela Kimura is set to digitally release a new song, called ”Chiisana Eiyu” (Modest Heroes), written as the ending theme of the upcoming three-part animated short film anthology by Studio Ponoc.

Studio Ponoc is a Japanese animation company founded in 2015 by the former lead film producer for Studio Ghibli. Following the hit of its first animated feature film, Mary and the Witch’s Flower released last summer, Ponoc recently launched a new project called the “Ponoc Short Films Theater.” The upcoming anthology Modest Heroes featuring Kimura’s new song is the project’s first release.

Back in May, Kimura began writing the song with the three directors of the film’s segments - - all of whom are former Studio Ghibli animators including Mary and the Witch’s Flower director Hiromasa Yonebayashi - - and worked closely with them to build up the imagery. The emotions in the song are depicted from the perspectives of children and the grownups around them, switching back and forth between the two.

“Chiisana Eiyu” was produced by Shinobu Watanabe of the Japanese band Asparagus, who has worked with Kimura on a number of her catchy pop hits including “Tree Climbers” and “Ring a Ding Dong.”

The acclaimed photographer Masayoshi Sukita, known for his iconic shots of musicians including David Bowie, Iggy Pop, and YMO, shot the latest portrait of Kimura.

Kaela Kimura will also sing the opening theme song for Modest Heroes. ”Chiisana Eiyu” will be released digitally on Wednesday, Aug. 22.
