Toshiki Miyamizu (宮水 俊樹 Miyamizu Toshiki ) is the estranged father of Mitsuha and Yotsuha Miyamizu. Following his wife, Futaba's death, he rejected the Miyamizu shrine and its traditions to pursue a career in politics. He is shown to be a very busy man and became the mayor of Itomori two years after his wife's death, having held the position for 4 years as of 2013.
He was, under his daughter's suggestion, responsible for the evacuation of Itomori during the Comet Tiamat incident. As all residents survived, he was scrutinized by the media for some supposed "hidden agenda". It is unknown what happened to him at the end of the film, as no mention is made of him in the film past the Comet Tiamat incident.
