Amassed by Bridgestone founder Ishibashi Shōjiro, this is one of the best French impressionist collections you will find in Asia. Though European painting is undoubtedly the main attraction (think Renoir, Ingres, Monet, Corot, Matisse, Picasso, Kandinsky et al), the museum also exhibits sculpture and some works by Japanese impressionists, as well as European pieces that employ abstract or neoclassical aesthetics.
Note that the museum is currently closed for major renovations. Check their website for updates.
