Map Production
After taking the tour of the map and exploring its contents we learn some important information. First, the map centers on China, but includes the entire world; second, Umemura Yahaku 梅村弥白 reprinted the map in Kyoto; third, the original map was produced in Suzhou by Wang Junfu.
The fact that the map was printed in Japan can be confirmed by a look at its reverse side. Like the Maclean copy, all extant copies of this map are folded and include two covers, a format that is typical for commercial maps in Japan at the time. In Edo Japan, folded sheet maps could be printed in various sizes, ranging from smaller prints folded into tiny easy-to-carry pocket maps to much larger prints. Here the back and front covers are thick paper stock wrapped in blue colored sheets that are glued to the back of the map, typically but not always at opposite corners of the folded sheet and with the front cover featuring a title slip (Fig. 2), pasted in the center of the top cover. Here it reads ‘Map of the Great Ming’ (Dai min ezu 大明繪圖), an abridged title from the proper title found on the map itself.

Although copies of this map are kept in many libraries and archives in Japan and around the world, the MacLean copy is unique in two ways: first, it features covers that measure approximately 30.4 x 21.2 cm., which results in a four by six grid fold for the entire map, whereas most other Umemura covers measure approximately 27 x 19.5 cm., resulting in a five by seven grid fold for the map. Second, the MacLean copy shows signs that originally the two vertical sheets had been folded separately as a two-sheet set, each sheet with its own front and back covers: the back of the map still bares the blue outline traces of two covers that were removed when the two sheets were later glued together to make a single folded sheet. This suggests that the MacLean copy might have been originally sold as two separate sheets, each folded into their own covers. On the front of the map, this assumption of two separate sheets remounted together is confirmed where the neat line at the bottom center is misaligned as seen near the two characters of the South Pole (Nanji 南極, Fig. 1A).

The Umemura family that produced this print ran a print shop at the crossroads of the Gojō 五條 and Teramachi 寺町 streets in the southeastern part of Kyoto. Their print shop was known for bringing Chinese works onto the Japanese print market, including books that rearranged and borrowed from Ming-era works of geography as well as maps. The map's printing can be dated to shortly before 1706, as it is absent from a 1699 Umemura catalogue but appears in catalogues dated to 1706 and 1715 (Kaida, “World Maps”). Scholarship on the market prices of the early prints sold by Umemura indicate that it was a mid-range print with a stable price of 5 monme between 1706 and 1715 (Miyoshi, “Shuppan sareta sekaizu,” 107).
Map Genealogies
As noted above, the Umemura print is a faithful reissue of a map printed in the Chinese city of Suzhou in 1663 by Wang Junfu 王君甫 (act. 1650-80). The Wang map is entitled Complete Map of All under Heaven and the Nine Frontiers, with all Countries, Human Traces and Route Itineraries (Tianxia jiubian wanguo renji lucheng quantu 天下九遍萬國人跡路程全圖, Fig. 3).

As we have seen, Umemura retained on the MacLean map, in the upper left corner, the original signature by Wang Junfu (Fig. 4).

At the same time, the re-carving process by Umemura introduced important changes in the contents of the map, most important of which is the production statement flanking the small title of the bottom margin in the bottom right corner of the map. To the right and left of the title, two phrases are inserted in small font: “bookshop in the imperial capital” and “re-issued by Umemura Yahaku” (Fig. 1B).

A second significant change is the replacement of the earlier title's first two characters of Tianxia 天下 (J. Tenka) with Dai Min 大明 (Ch. Da Ming), explicitly referring to the fact that the map primarily presents the administrative structures of a Chinese state that no longer existed (Fig. 5). Beyond changes in print, Umemura's reissue also applied bright colors to highlight rivers and oceans, mountains, and provincial capitals.
