This publication is the result of a collaboration with Leiden University Libraries. The editors are Kuniko Forrer and Matthi Forrer. Kuniko is a book historian and an authority on the Dutch language who has worked at Japan Museum Siebold Huis since 2012. She has a doctorate in Dutch literature and book studies. Matthi is an art historian and authority on Japan, and the first person appointed to the Siebold professorship at Leiden University. He is currently a senior researcher on the Japanese and Korean collection at Leiden’s Wereldmuseum. The editors share their love for Japan, and Siebold’s Nippon in particular, from the perspectives of their distinct specialist fields.
