Kimura Kaela's new song "Himawari" has been picked up as the theme song for Hashimoto Ai's starring film "Birthday Card". 

"Birthday Card" is a human drama that portrays the growth of the protagonist 'Noriko' who receives encouragement by the birthday cards sent every year by her mother who passed away when Noriko was just 10 years old. 'Noriko' will be played by Hashimoto and her mother 'Yoshie' will be played by Miyazaki Aoi. 

"Himawari" was written after Kimura had read the movie's script. It was composed by Qururi's Kishida Shigeru, an artist who Kimura admires and respects.

You can preview the song in the trailer for the movie below.
