English: A drawing of a trade ship heading from Nagasaki to Vietnam, from the Gaiban Shokan. This book was prepared as a reference work for "Gaiban Tsusho," the compilation of diplomatic documents of the Tokugawa shogunate, prepared by Kondo Seisai (1771 - 1829), who served as the magistrate of Nagasaki and the magistrate of books and records. It contains copies of diplomatic papers, including 33 certificates impressed with the shogun's vermillion seal for officially authorized trips to Annam (Vietnam), the Netherlands, and Luzon (in the Philippines). It was completed in the first year of Bunsei (1818), and the two sets of two-volume were presented to the Tokugawa Shogunate in 1819. One copy was kept at the Momijiyama Library, and the other, at the Shoheizaka-Gakumonjo run by the shogunate.
