Akika Shimazu, a 38-year-old former Takasago city assembly member, won a by-election for the Hyogo prefectural assembly in the Takasago city district on Sunday, according to Asahi Shimbun. She defeated Yasutaka Katayama, 66, a former deputy governor who had served as a close aide to Governor Motohiko Saito. The seat, which carries one mandate, was vacated by the death of an incumbent prefectural assembly member from the Liberal Democratic Party.
The district had 71,432 eligible voters on election day, and turnout came to 29.23 percent, down from 32.59 percent in the previous contest, the newspaper reported.
Shimazu first won a city assembly seat at age 26 and served three terms there. She received the recommendation of the LDP's prefectural federation, which framed the race as a memorial election for the deceased lawmaker, but she ran without an official party affiliation, saying she wanted broad support. LDP members of the national Diet and local assembly members campaigned for her, and her campaign ran an organizational effort that included visits to companies and groups.
Why it matters
The result is a setback for Katayama, whose candidacy was tied to the record of the Saito administration. Katayama had left his post as deputy governor after a 2024 internal whistleblower document, written by a now-deceased former prefectural bureau chief, raised allegations concerning Governor Saito and others. Katayama, who was at the center of the prefecture's internal investigation into the matter, resigned saying he had caused confusion in prefectural governance, according to Asahi Shimbun.
Shimazu's win also shows that an LDP-backed candidate could prevail in a district while keeping the party label off the ballot, and while avoiding sustained discussion of the governor's record.
A campaign focused on connections, not the governor
During the race, Shimazu stressed that she wanted to serve as a link between the prefectural government and the city of Takasago. On the subject of how Governor Saito runs the prefecture, she said early on that she would judge each policy on its merits rather than take a blanket stance. As the campaign went on, she said she wanted the election to be one that argued policy, and she avoided further comment on the governor's administration.
Katayama entered the race with the weight of the whistleblower controversy behind him. The document, which surfaced in 2024, contained allegations against Saito and others, and the prefecture's internal inquiry into it became the episode that ended Katayama's time in the administration.
The by-election was called after the death of the LDP prefectural assembly member who had held the Takasago seat. Under the memorial-election framing, the LDP's prefectural federation threw its recommendation behind Shimazu, but she chose to stand as an independent, a decision she explained as an effort to reach beyond the party's usual base. Her campaign combined support from national and local LDP politicians with outreach to businesses and organizations, according to the report.
Turnout of 29.23 percent was lower than the 32.59 percent recorded at the last election in the district, a decline of roughly three percentage points.
What to watch is whether the outcome shapes how the LDP handles future races in Hyogo, particularly whether candidates continue to run without the party label while accepting its backing, and whether the governor's record remains a live issue in the prefecture's local contests.
