To commemorate its 90th anniversary, Toyo Bunko, Japan's largest Asian studies library, is exhibiting in its museum the Iwasaki Collection, originally collated by founder Hisaya Iwasaki (1865-1955), Mitsubishi's third president.

Displayed works include Japanese, Chinese and English writings, such as the Important Cultural Property "Rongo Shikkai," a record of Confucius and his disciples' words, and the National Treasure "Moushi" ("Classic of Poetry"), which was written around the seventh to eighth century.

In addition, the museum will showcase a selection from its own collection of ukiyo-e works and will, for the first time since its foundation, reveal its erotic shunga paintings by artists such as Katsushika Hokusai and Utagawa Kuniyoshi; Aug. 20-Dec. 26.
