Yokohama Mayor Yamanaka Admits Power Harassment; 7 Violations Confirmed July 30

Yokohama Mayor Takeharu Yamanaka admitted on July 30 that he committed serious workplace harassment after a third-party investigation confirmed seven separate violations. The probe found he yelled at subordinates, called them dehumanizing names, threw documents, and abused his personnel authority. Yamanaka apologized but said he intends to remain in office and fix the problems he caused.

What the investigation found

Three lawyers appointed by the Yokohama City Council examined complaints from the then-head of the human resources department, who went public in January. The report confirmed Yamanaka called staff “useless,” “human scum,” “old lady,” and “moron.” He yelled, threw documents, and made threats like “disembowel yourself if you fail to secure the international conference bid.” He also prohibited certain staff from entering his office and made unexplained personnel transfers that caused mental distress and sick leave claims.

Scope of the abuse across city staff

The investigation surveyed 746 city employees and former workers. Of 294 who responded, more than 60 percent said they witnessed or heard about suspected abuse. Multiple staff members took sick leave for adjustment disorders and other mental health issues linked to the harassment. The lawyers concluded the mayor’s behavior was “extremely serious” and that he used his superior position to psychologically pressure and control subordinates through improper use of hiring and firing authority.

Yamanaka’s response and stated intent

Yamanaka told reporters on July 30 that he takes the findings “extremely seriously” and apologized for affecting staff morale and safety. He said he would not contest the report and pledged to rebuild a workplace where employees feel secure. When asked about resigning, he declined, stating he would focus on fixing the organizational problems and improving the workplace environment. The city council passed a unanimous resolution in March calling for the investigation.

Organizational failures and next steps

The report cited inadequate oversight by deputy mayors and lack of harassment prevention systems for special officials as root causes. The Japanese Communist Party’s city council caucus called on Yamanaka to explain himself to the public and demanded implementation of a harassment prevention ordinance covering elected officials. The report recommended new safeguards and monitoring to prevent recurrence.

Final Thoughts

Yamanaka’s admission marks a rare public accountability moment for a sitting Japanese mayor, though his decision to stay in office leaves questions about consequences. The confirmed pattern of abuse across seven categories and 60 percent of staff witnessing it signals systemic dysfunction requiring urgent structural reform.
