Minoru Yamagishi is a supporting character in the anime and live-action adaptations of Weather Woman. He is portrayed as an old high school flame of the protagonist, Keiko Nakadai. His role in the story is that of a former romantic interest who becomes caught in the middle of the escalating rivalry between Keiko and Kaori Shimamori. Because of his past connection to Keiko, he is drawn into the conflict that arises when Kaori returns to the television station and begins competing with Keiko for the weather reporter position. His background as someone from Keiko's youth is established, but his personal motivations are not deeply explored within the narrative. Minoru does not undergo significant character development and does not possess any notable abilities; his primary function is to serve as a link to Keiko's history and to add personal stakes to the workplace rivalry.
