Japan's Prosecutor General Naomi Umemoto resigned Wednesday, apologizing for a series of internal scandals that occurred during her term [1, 2, 3].
The resignation marks a period of significant instability for Japan's public prosecution office, as repeated ethical lapses have eroded public confidence in the legal system's integrity.
Umemoto, 64 [2], held the position since July 2026 [1]. During a press conference at the Supreme Public Prosecutors Office in Kasumigaseki, Tokyo, she addressed the failures of her administration [2, 3].
"As the person who was in the position of final responsibility for the management of the prosecution, it is truly regrettable and I feel very sorry," Umemoto said [1].
Her tenure was marred by multiple controversies involving the Special Investigation Department. Two prosecutors were brought to criminal trial for conducting improper interrogations [1]. Additionally, one prosecutor was fired for disciplinary reasons following a scandal involving an inappropriate sexual relationship [1].
These events followed a broader climate of scrutiny for the prosecution, including the September 2024 retrial acquittal of Iwao Hakamada [1]. Umemoto emphasized the need for a shift in institutional values to prevent further misconduct.
"I believe the most important thing is to thoroughly implement values that balance the pursuit of truth with fair and neutral interrogations," Umemoto said [1].
To address these systemic issues, the prosecution office has implemented ethics training for all prosecutors during the 2026 fiscal year [6].
Despite the scandals, Umemoto expressed gratitude to those who supported her during her leadership. "I was able to reach this day thanks to the support of many people," Umemoto said [2].
“"As the person who was in the position of final responsibility for the management of the prosecution, it is truly regrettable and I feel very sorry."”
The resignation of Naomi Umemoto reflects a deepening crisis of legitimacy for Japan's prosecution services. The combination of criminal charges against prosecutors for interrogation tactics and disciplinary dismissals suggests a systemic failure in oversight. By introducing mandatory ethics training in 2026, the office is attempting a structural reset to restore the 'fair and neutral' image required for judicial credibility.
