Osaka-jō Hall features an arena with a maximum capacity of 16,000 people (site area 55,244 m²), as well as the multipurpose Shiromi Hall and a convention hall. It is in a prime location, about a 5-minute walk from Osakajō-kōen Station. There is no on-site parking at Osaka-jō Hall, but multiple paid parking lots are available within about a 15-minute walk; wheelchair users arriving by car are advised to contact Osaka-jō Hall in advance by phone. The arena is equipped with extensive sound-focused facilities, allowing audiences to enjoy highly immersive performances from any seat and helping create a strong sense of unity between performers and spectators—one reason it can host events with crowds of over 10,000. Usage fees vary depending on the event, so details should be checked per event. In 2020, many concerts and live shows were canceled due to COVID-19, but some events have gradually resumed with measures such as electronic ticketing and disinfectant supplies.
