The City Museum of Art opened in 1999, three years after Taro Okamoto, one of Japan's leading artists of the 20th century, passed away. The museum has a collection of 1,779 works donated to Kawasaki City by Taro Okamoto. Various events are held, including special exhibitions and permanent exhibitions, as well as museum tours and workshops.
The symbol tower of the Taro Okamoto Museum of Art is the 30m tall "Mother's Tower". Based on a prototype created with the image of "the strength of a giant tree deeply rooted in the earth," "the gentleness of a rich and plump mother," and "eternal life blazing toward the sky," it is faithful to Taro Okamoto's intentions. It was reproduced and produced.
