A mid-career professional at the Bank of Japan filed a wrongful termination lawsuit in the Tokyo District Court on October 1, just four days after receiving a written order to leave the premises and step down from her role. The plaintiff, a woman in her 50s identified as A-san, alleges that her dismissal on August 27 came in direct retaliation for internal whistleblowing regarding compliance and technological vulnerabilities within the central bank’s core settlement infrastructure.
Lawsuit Filed in Tokyo District Court Over Dismissal
The legal filing asks the Tokyo District Court to confirm A-san’s employment status and award damages for emotional distress. A-san, who specialized in financial systems and management at private financial institutions before joining the central bank on April 1, held a clean attendance record with no prior disciplinary warnings. Despite this, management delivered a refusal of permanent employment on August 27, followed by a formal exit order on September 4 that barred her from entering central bank offices. On September 30, her legal team also filed a provisional disposition petition requesting job preservation and interim wage payments while the primary lawsuit proceeds.
Compliance Deficiencies in the Central Bank Settlement System
The dispute centers on system reviews A-san conducted after starting her position. Tasked with evaluating whether Bank of Japan systems met external standards, she compiled audit reports highlighting discrepancies with the FISC Safety Guidelines for Financial Information Systems and international wire standards like ISO 20022. The core “BOJ-Net” system lacks electronic messaging required to handle funds transfer refusals, returns, or cancellations under FATF Recommendation 16. While international counterparts at the European Central Bank and in the United States operate compliant infrastructure, Japanese commercial banks are left to manage anti-money laundering obligations manually while settlement executes instantaneously.

A-san faces exclusion after filing internal whistleblowing reports
After a supervisor remarked on May 18 that her findings could not be shared with other departments, A-san escalated the documents on May 21 directly to the head of the inspection division and the head of the personnel department. Under Bank of Japan regulations, submitting reports to designated executives constitutes formal internal whistleblowing. Following these submissions, A-san’s legal representation notes she was gradually excluded from operational meetings and email chains, with supervisors dismissing the exclusions as oversights. When she escalated the unresolved issues directly to the governor and deputy governor on August 28 and August 31—and subsequently notified the Ministry of Finance and the Financial Services Agency—the central bank issued the physical entry ban.
Bank of Japan denies claims of compliance penalties
Represented by attorney Katsuyuki Nakagawa, the plaintiff challenged the legitimacy of the bank’s stated rationale during a press conference in Tokyo on October 2. In written correspondence responding to content-certified mail from the plaintiff’s legal counsel, the Bank of Japan’s personnel director maintained that A-san failed to demonstrate adequate flexible planning and judgment as a management-level employee capable of accounting for organizational constraints. Nakagawa countered that the central bank penalized an employee for insisting on adherence to international compliance standards over internal administrative convenience.

What core technological shortfall did the plaintiff identify in the Bank of Japan’s network?

A-san submitted her internal compliance report to division heads on May 21. After facing exclusion from meetings, she received notice of permanent employment refusal on August 27, followed by a formal exit and entry ban order issued in writing on September 4.
