Footage released Tuesday shows a Tokyo prosecutor insulting a defendant during a series of interrogations conducted in 2021 [1].
The video raises concerns about the legality of interrogation tactics within the Tokyo District Public Prosecutors Office's Special Investigation Department. While the footage captures derogatory language, the legal system has declined to penalize the official involved.
The recordings cover four separate interrogation sessions that took place on June 3, June 23, July 2, and July 5, 2021 [1, 2]. In the videos, a 57-year-old male prosecutor is seen berating Naoyuki Ikuta, 52, the president of a solar power company [3, 4]. Ikuta was accused of defrauding financial institutions of approximately 2.2 billion yen [1].
During the sessions, the prosecutor reacted with frustration to the defendant's silence and alleged false statements. "If you think the investigative agency is being looked down upon, you should understand what happens," the prosecutor said [1]. He further told Ikuta, "To view the prosecutors' office as the enemy means you are anti-social, completely" [1].
In other segments of the footage, the prosecutor told the defendant, "Don't glare, hey," and accused him of lying too easily [1].
Following these events, the prosecutor was hit with a criminal complaint for abuse of authority by a special public officer. However, authorities later decided not to indict the prosecutor, citing insufficient evidence [2, 5].
Ikuta received an 11-year prison sentence in his first trial [1]. The release of the video on May 12 has renewed debates over the transparency of the Japanese interrogation process, and the lack of accountability for officials accused of misconduct [1, 2].
“"To view the prosecutors' office as the enemy means you are anti-social, completely."”
The dismissal of charges against the prosecutor, despite the existence of video evidence, highlights the high legal threshold for proving 'abuse of authority' in Japan. This case underscores a systemic tension between the state's goal of securing confessions in high-value fraud cases and the protection of defendants' rights against psychological coercion during custody.
