Osaka International Convention Center (Grand Cube Osaka)

Updated: Jan 12

*The center is temporarily closed from December 1, 2023 to March 31, 2024.

Osaka International Convention Center, built on the banks of the Dojima Ohashi Bridge over the Dojima River, was designed by the world-renowned architect KUROKAWA Kisho (1934-2007). As its nickname "Grand Cube Osaka" suggests, it is characterized by its sophisticated cube-shaped architecture.

It is a steel-framed structure with 13 floors above ground and 3 floors below. It opened in 2000 as a comprehensive exchange facility for people, goods, and information from around the world. The interior is designed in a " traditional Japanese " style, with the walls and ceiling of the main hall and entrance hall inspired by origami paper and pine branches, respectively. The Special Conference Hall, a hemispherical space designed by Kurokawa in the image of the earth, was the main venue for the G7 Osaka-Sakai Trade Ministerial Meeting in October 2023.
