Manuscripts

Only two copies of the map are known today. Both have been preserved in Japan and show later modifications.

The map currently in Ryūkoku University (hereafter, Ryūkoku copy) has gathered scholarly attention since the early 20th century. It is 158 cm by 163 cm, painted on silk. It is presumed that the Ryūkoku copy was created in Korea but it is not clear when the copy was brought to Japan. One claims that it was purchased by Ōtani Kōzui and others assume that it was obtained during the invasion of Korea (1592-1598) and given to the West Honganji temple by Toyotomi Hideyoshi. It contains some place names of Korea that are newer than 1402, suggesting that the Ryūkoku copy was partially modified from the 1402 original around 1470s and 1480s.

Another copy (Honkōji copy) was discovered in the Honkōji temple of Shimabara, Nagasaki in 1988. It is 220 cm by 280 cm, much larger than the Ryūkoku copy, and painted on paper. It seems that the Honkōji copy was created in Japan during the Edo period. The place names of Korea suggests that it was revised around 1560s.

There are two copies of maps in Japan that are related to the map. One (Honmyōji copy) housed in the Honmyōji temple of Kumamoto is known as the "Map of the Great Ming" (大明國地圖). The other (Tenri copy) at Tenri University has no title and is tentatively called by a similar name (大明國圖). They are considered to be later adaptations of the original. The most important change is that place names of China are updated to those of the Ming Dynasty while the original showed administrative divisions of the Mongol Yuan Dynasty.

Based on a legend of the temple, it has been assumed naively that the Honmyōji copy was given to Katō Kiyomasa, the ruler of Kumamoto, by Toyotomi Hideyoshi in preparation for the Korean campaigns. However, the Seonjo Sillok of Korea reports that in 1593 the son of a Korean official who had surrendered to Katō copied and offered map(s) of China and Korea to him. This may refer to the extant Honmyōji map.
