Osaka-jō Hall (大阪城ホール Ōsaka-jō Hōru?), is a multi-purpose arena, in the Kyōbashi area, of Osaka, Japan. The hall opened in 1983 and can seat up to 16,000 people. Built on a site area of 36,351 square meters, part of its form uses stone walls, modeled after those of the Castle and it won the Osaka Urban Scenery Architects Prize Special Award in 1984.
The hall may be reached on a short walk from either Osaka Business Park Station on the Osaka Municipal Subway Nagahori Tsurumi-ryokuchi Line or Osakajō-kōen Station on the JR Osaka Loop Line. The hall is located in Osaka-jō Park, near Osaka Castle and is across a river from two other smaller concert halls. It is used for some sports, such as judo championships and is popular for concerts, with many native and international pop and rock music artists. Each year, 10,000 people come to the hall to participate in a performance of Beethoven's Symphony No. 9.
