Whistleblowing remains one of the most effective tools for detecting corporate misconduct, driving legislative reforms across the globe. In recent years, EU member states have implemented comprehensive whistleblower protection laws under the EU Directive, while the US Department of Justice has strengthened its rewards framework through a new pilot programme. Japan has also moved to enhance protections, following its 2020 reforms to the Whistleblower Protection Act with a further amendment in June 2025 aimed at expanding coverage and reinforcing safeguards. This session will explore these developments, compare approaches across jurisdictions and consider their implications for compliance programmes, investigative practices and corporate culture in Asia and beyond.
