An art museum in the U.S. capital on Saturday kicked off the first exhibition in over a decade showcasing many of the paintings and sketches from its extensive collection of works by ukiyo-e master Katsushika Hokusai (1760-1849).

The yearlong exhibition at the Freer Gallery of Art, featuring about 120 works by one of Japan's most iconic painters, was launched partly in celebration of the 2020 Olympics, according to the museum in Washington.

"Hokusai: Mad about Painting" offers visitors a rare chance to see the extent of the museum's Hokusai collection, which it said is not loaned to outside institutions at the desire of the museum's late founder Charles Freer.
