This is shin osaka station and not Osaka station. make sure you download the maps of the subway and JR line and have an idea on which lines and direction you need to be. Enjoy!
Major station in Osaka along the Shinkasen lines between major cities in Japan ( from Tokyo to Hakata). There're express and local trains to the airports and to other major cities of the Prefecture.
