Johannes Gerhard Frederik van Overmeer Fischer began as a clerk at Dejima, the Dutch station in Japan, and he was later promoted to warehouse master. During the span of his stay in Japan, Fischer's access to Japanese culture was limited but he amassed a considerable collection of objects. This material was taken back to the Netherlands in 1829. In 1833, he published Bijdrage tot de kennis van het Japansche rijk (Contribution to the knowledge of the Japanese Empire).
