Example Input: Question: When did the Tokyo Kaisei school change it's name? Passage:The Japanese exhibition at the fair was the product of years of preparation. The empire had received its invitation in 1871, close on the heels of the Meiji Restoration, and a government bureau was established to produce an appropriate response. Shigenobu Okuma, Tsunetami Sano, and its other officials were keen to use the event to raise the international standing of Japanese manufactures and boost exports. 24 engineers were also sent with its delegation to study cutting-edge Western engineering at the fair for use in Japanese industry. Art and cultural relics at the exhibit were verified by the Jinshin Survey, a months-long inspection tour of various imperial, noble, and temple holdings around the country. The most important products of each province were listed and two specimens of each were collected, one for display in Vienna and the other for preservation and display within Japan. Large-scale preparatory exhibitions with this second set of objects were conducted within Japan at the Tokyo Kaisei School (today the University of Tokyo) in 1871 and at the capital's Confucian Temple in 1872; they eventually formed the core collection of the institution that became the Tokyo National Museum.
