The Special Collection Research Center recently acquired an early Japanese astronomy book titled 天経或問 (Japanese: Tenkei wakumon; Chinese: Tianjing huowen:"Questions and Answers on Astronomy"). Printed in 1730 in Tōkyō, it was a republication of a Chinese astronomy work supplemented with Japanese reading marks. Chinese Studies Librarian Liangyu Fu introduces us to this new acquisition.
