Suntory Museum

The Suntory Museum, which you can tour in about 30 minutes, is that fantastically modern-looking structure you see near the aquarium, designed by well-known architect Tadao Ando. It stages changing exhibitions in airy rooms against a dramatic background of the sea beyond its glass walls. Past exhibits have included posters by Toulouse-Lautrec, paintings by German expressionists, and glass by Emile Gallé; call or check the Meet Osaka quarterly for current information. There's also a 3-D IMAX theater with scenes so real you'll swear those fish on the screen are about to swim into your lap, a good museum shop, the Sky Lounge (perfect for taking a break), and a restaurant, Café Solare.
