The Japanese government has recently released an estimate stating the economic impact of the upcoming Expo could reach a staggering 3.6 trillion yen. This figure highlights the significance such a large-scale international event holds for the country's economy as it is expected to spark a wave of economic activity, including increased tourism, trade opportunities, and job creation.

In Japan, large international events like the Expo are usually viewed as opportunities to showcase the country's culture, advancements, and economic stability. They are considered platforms for potential growth and usually receive a lot of attention from both the general public and business sectors who eagerly anticipate the economic boost they bring.

Similar to the US or EU, hosting grand global events is considered beneficial economically. For instance, the hosting of the Olympics or international trade expos in these regions have typically yielded increased tourism, trade deals, and job creation. However, the actual economic gain can sometimes be overestimated and involves a significant initial investment.
