Tansa welcomes whistleblower support from everyone.

We investigate and report from the perspective of people who are affected. We do not take a "neutral" position.

With regard to cases which we start to investigative, we promise that we will protect whistleblowers in any way. Please provide information as specifically as possible. The Tansa team will review the information provided and contact you if necessary.

Case of whistleblowing

If you are inside a public institution or company and have witnessed or heard about organizational wrongdoing or corruption, your information can help those affected to be saved.

When submitting whistleblowing information, please keep the following in your mind:

Whistleblower Protection Act

It is legally permitted to be able to report not only to your organization but also to the media. This means that reporting to Tansa is also protected under the Whistleblower Protection Act.Part-time, temporary, or contracted workers can also report. Additionally, those who have left the organization can report if it is within one year of their resignation.

Your organization cannot dismiss a whistleblower. Other unfair treatments, such as demotion, pay cuts, or withholding of retirement benefits, are also prohibited. The organization cannot claim damages against the whistleblower based on the consequences of the whistleblowing.

Reports must pertain to legal violations by companies or public institutions. This includes “the laws concerning the protection of life, body, property, and other interests of citizens.”

Point to note

It is not recommended to use computers, mobile phones, or smartphones which are lent to you by your organization. When submitting information, please always use your personal computers, telephones and smartphones. Organizations may try to identify you as the whistleblower and penalize you under some pretext. We would like to ask you to contact us with the mindset of protecting yourself first.
