In both the United States and Japan, railways are a vital foundation supporting economic activity. In the U.S., major projects such as modernization along the Northeast Corridor are underway, and investment in rail-centered public transportation is accelerating ahead of mega events including the FIFA World Cup 2026. Meanwhile in Japan, alongside ongoing advancements in rail development and station-centered urban development in major metropolitan areas such as Tokyo and Osaka, network enhancements and customer-experience initiatives linked to international events have already been implemented. Investment by Japanese rolling stock manufacturers in the U.S. has also contributed to local communities. Against this backdrop, the railway sector has become a key area for sharing expertise and strengthening bilateral relations. This symposium will bring together government officials and railway operators to discuss expanding the economic impact of railway investment and leveraging mega events to enhance the customer experience.
