Main Hall at Osaka International Convention Center is the flagship auditorium of the venue also known as Grand Cube Osaka—an instantly recognizable landmark on Nakanoshima that regularly hosts major conferences, ceremonies, and concert-scale events. With a hall setup of up to 2,754 seats, it is built to handle both high-profile speakers and large productions, supported by flexible staging and audience configurations.
Inside, the experience feels modern and purpose-built: clean sightlines, efficient wayfinding, and a layout that keeps arrivals and intermissions smooth. Visitors often highlight consistent acoustics, comfortable seating, and the practical front-of-house facilities (foyers, cloakrooms, and on-site services) that make the whole visit feel organized from door to finale.
The exact address is 5-chome 3-51 Nakanoshima, Kita Ward, Osaka, Japan. For the most direct approach, head to Nakanoshima Station (Exit 2) and follow the signs toward the convention center entrance; drivers can use the venue’s underground parking.
