Osaka Metro, the subway system in Osaka, Japan, aims to contribute to the city's development through its urban MaaS (Mobility as a Service) concept called "e METRO." The app offers various features to enhance transportation services and improve the overall urban experience. One of the main functions of the app is the ability to search for transfer routes. Users can combine different modes of transportation, including subway, buses, other railway lines, shared bicycles, and taxis, to find the most convenient transfer routes to various locations in the Kansai region. Another feature is the option to reserve on-demand buses. Users in specific areas of Osaka, such as Kita-ku, Fukushima-ku, Ikuno-ku, and Hirano-ku, can reserve on-demand bus services and make online payments through the app. The app also allows users to purchase and use various mobile tickets that can be used on Osaka Metro's on-demand buses and other services. Additionally, users can access subway operation information, such as train schedules, congestion updates, and delay certificates. Furthermore, the app provides useful information such as recommended places to visit and event updates in Osaka, making it a convenient tool for residents and visitors alike. Osaka Metro plans to continue adding new services to further enrich and enhance the quality of life for its users.
