Osaka Metro reported a remarkable profit of 9.7 billion yen thanks to activities related to the Expo. The substantial increase in profits is attributed to the high influx of both domestic and international tourists that leveraged the transportation service to attend the Expo. Specific details about the revenue, such as their main sources and distribution of expenditures, have yet to be disclosed.

In Japan, news about public corporations, particularly those related to transportation, like the Osaka Metro, making a profit is crucial. It underlines the economic health of the sector, impacts the decisions of future investments, and is part of public accountability as these corporations are indirectly owned by taxpayers.

In the US or EU, news about profits of public transportation companies, especially those tied with significant public events, is also considered useful. It provides insight into the efficiency and financial health of government-run companies, which is critical for public oversight and future planning.
