Public sentiment towards the Expo, a significant cultural event in Japan, experienced a positive turnaround in May, as per a recent analysis. Online posts capturing various happenings and impressions of the event witnessed a positive shift, reflective of an increased level of public interest and approval. The exact factors leading to this change remain to be further discussed in the article.

The Expos, often held in Japan, are considered a part of the country's rich cultural heritage. Japanese people consider these exhibitions crucial in showcasing the country's culture, technological advances, and overall development. Both mainstream and social media platforms in Japan actively engage in reporting and discussing these events, influencing public opinion about them.

Similar to Japan, expos or fairs (such as the World’s Fair) held in the US or EU are significant cultural and economic events, sparking widespread public interest. They too witness active media attention and commentary, impacting public perception. However, the level of cultural significance and regular frequency seen in Japan is rarer in Western contexts.
