Tansa is an independent, nonprofit, investigative newsroom based in Tokyo. Our investigations reveal - and aim thereby to end - wrongdoing by the powerful, such as government bodies and corporations.

Our investigations reveal - and aim thereby to end - wrongdoing by the powerful, such as government bodies and corporations. We approach our work by considering what needs to change in order to achieve redress for injustice and ensure that others are not harmed by similar wrongdoing in the future. In 2023, Japan ranked 68th in Reporters Without Borders' World Press Freedom Index. The country's major media organizations, prioritizing their own business interests, often fail to sufficiently monitor power or to speak up for the victims of its abuses. We believe independent, investigative journalism is essential for the Japanese public. As governments, corporations, and criminals increasingly work across borders, so too must the journalists who investigate them. In 2018, Tansa became Japan's first official member of the Global Investigative Journalism Network (GIJN), which is comprised of 244 independent, nonprofit media organizations in 90 countries.
