[9] In 2016, Yamato adapted the George Asakura manga Drowning Love into a film titled Oboreru Knife (溺れるナイフ), starring Nana Komatsu.

[10] Yamato chose to adapt the story because young girls could relate to the main character's experiences.

[11] For her third major film, Yamato wrote and directed Hot Gimmick: Girl Meets Boy, a 2019 adaptation of the Miki Aihara manga Hot Gimmick, about a teenager who gets blackmailed by the son of a powerful corporate executive.

[13] That same year, Yamato organized and produced 21st Century Girl (21世紀の女の子), an anthology of short films by directors born in the 1980s and 1990s.
