The Chiba City Museum of Art is architecturally stunning. They preserved an old bank building and built a modern structure right over it, so you can see the original bank interior as soon as you walk into the entrance hall. Most of the artworks on the 5th floor are by Japanese artists, featuring an impressive collection of Ukiyo-e and other fine Japanese art. The admission fee is also very affordable.
Originally, the museum building was an old bank from 1920s. They moved the bank building (actually dragged) by Hiki-Ie method (pulling a whole house), then restored in the modern concrete building. Their collection includes Ukiyoe (woodblock prints)like Hiroshige, Hokusai and some modern art Yayoi Kusama as well.
Museum shop and small cafe on the 1st floor, library on the 4th and exhibitions on the upper floors above 5th. You will need to purchase a ticket to see the exhibitions.
