This cultural complex features a Gallery for exhibitions and an IMAX Theater with a gigantic 3-D screen, incorporated with a Museum Shop, cafe, and lounge. Its unique architectural concept with a drum in the shape of an inverted cone embracing a sphere and two rectangular parallelepipeds stretching outward to the sea was designed by Osaka's own internationally-renowned architect Tadao Ando. The Gallery, which aims to showcase arts and designs in "easy-to-understand and enjoyable" exhibitions, owns a well-balanced collection of over 15,000 poster masterpieces by artists, such as Toulouse-Lautrec, Mucha, and Cassandre.
