Cloppenburgh's map of Japan is a reduced version of Jodocus Hondius' map of Japan from the same period. This is edition is referenced by Walter as being a later French edition, with the IA in IAPONIA erased, and evidence of the removal of these letters is present. However, this is a curiously folded copy, which leads us to conclude it was issued in a book, rather than an addition of the Mercator Minor. Korea is an island and Japan is configured after Hondius, at least 40-50 place names. A nice dark impression. The notation Tom. 2. Pag. 392 may give a good lead to is source.
Johannes Cloppenburg (sometimes Cloppenburgh; also H. Jan Evertsz and Johannes Everhardus) was a Dutch cartographer. Based in Amsterdam, he was active between roughly 1610 and 1644. He worked closely with the Hondius/Jansson firm and is credited with the 1630 edition of the Atlas Minor.
