In recent years, digital technology-based trading has dramatically been improving users’ access to markets, and digital platforms, in particular, have been playing a significant role in such trading. Meanwhile, some concerns have been raised over digital platform markets, such as transparency and fairness.
Against this backdrop, the Ministry of Economy, Trade and Industry (METI) has been advancing development of rules for markets surrounding digital platforms, the building of a framework for helping stakeholders share challenges that they are facing, and conducting comprehensive surveys for digital markets that are changing dramatically.
Act on Improving Transparency and Fairness of Digital Platforms (the Transparency Act)
Aiming to improve the transparency and fairness of digital platforms, the Act on Improving Transparency and Fairness of Digital Platforms (the Transparency Act) was established on May 27, 2020, promulgated on June 3, 2020, and enforced on February 1, 2021.
The Act stipulates necessary measures for digital platforms, including requirements of digital platform providers to disclose terms and conditions and other information, secure fairness in operating digital platforms, submit a yearly report on the current situation of business operation, and conduct self-evaluations.
