Despite the anticipation for the Expo in Japan, there are reportedly more than 1.4 million unused tickets. The high turnout was anticipated but not achieved, raising concerns about ticket sales strategy and audience reach. Efforts are being made to probe into the reasons behind these numerous unused tickets and potentially find ways to put them into use to boost expo attendance.

Expos are significant cultural events in Japan and are often used to showcase the nation's advancements, history, and culture. The low turnout to such a crucial event might raise eyebrows concerning promotional strategies or maybe a reflection of the current social attitudes towards such events. Public opinion is generally divided, with some arguing for a review of ticket sales procedures, and others attributing the discrepancy to possible overestimations of the turnout.

In contrast to the situation in Japan, events like expos in the United States or the European Union often sell out and have a high attendance rate. This disparity may be due to the different promotional strategies employed, as well as cultural differences in attitudes towards such events. However, it is also common for such issues to arise and be handled swiftly to improve attendance and event success.
