Guest Lecturer: Shungo Omiya (Japan Fair Trade Commission)

On July 24, 2025,as part of the Managerial Economics course, we invited Mr. Shungo Omiya from the Japan Fair Trade Commission (JFTC) to give a special lecture titled "Merger Review and Economic Analysis."

In his talk, Mr. Omiya provided an overview of the history and organizational structure of the JFTC, followed by a detailed explanation of how economic analysis is utilized in the practical enforcement of competition policy, with a focus on merger review.

He introduced analytical methods used for market definition—such as price correlation analysis and diversion ratio analysis—using real-world examples, including the merger between Z Holdings and LINE in the code payment market.

The lecture concluded with an engaging Q&A session, during which participants actively exchanged opinions and deepened their understanding of how economics is applied in competition policy practice.
