“Old Pine Tree and Peacock,” by Ito Jakuchu. (Ito Jakuchu)

To accommodate those who want a first, second or third look before the mid-18th century works are returned to Japan, the gallery announced extended hours for the last weekend. On April 27, 28 and 29, the show will be open until 8 p.m.

“Colorful Realm: Japanese Bird-and-Flower Paintings by Ito Jakuchu” has had an average of 7,100 visitors each day, placing it in the top 10 exhibitions at the gallery for daily attendance.

Previous attendance milestones at the gallery include “Treasures of Tutankhamun” in 1961 and 1976, “The Art of Paul Gauguin” in 1988 and a showing of the “Mona Lisa” in 1963. Some of the most popular shows, such as a Vermeer exhibition in 1995 and 1996, have prompted extended hours.

As of Thursday, 172,000 visitors had seen the work of Jakuchu, 30 scrolls that had never been seen outside Japan and that the gallery presented in a templelike setting in the West Building.

The cafe and the gift shop will also be open late this weekend.
