The World Expo's Sumitomo Pavilion has become enmeshed in a ticket-scalping scandal as high-value priority tickets are being resold at inflated prices. These activities have been reported to be widespread, tarnishing the reputation of the expo. Details about the individual or group perpetrators are still unclear, while investigators are diving into the case to both curb the illicit trading and hold the offenders accountable swiftly.

Ticket scalping has long been an issue in Japan, especially with high-demand events like concerts or expos. Japanese society generally frowns upon such unethical behaviors. Additionally, Japan has legal measures in place including the recent "Ticket Scalping Law" to prevent and penalize these practices for the sake of consumer protection and fair-trade ethics.

Much like Japan, the US and EU confront similar issues of ticket scalping, especially for sports events and concerts. There are laws in place to curb these illicit activities, but enforcement varies by states in the US, and by countries in the EU. The existence of digital platforms has added a layer of complexity to the issue.
