Japanese Ancient Maps Excluded Dokdo – Takeshima Part IV
Old Japanese Maps of Shimane Prefecture Show Japan’s Historical Territorial Limits
“If Dokdo was an inherent part of the nation of Japan as her MOFA insists, why do historical Japanese maps consistently exclude Dokdo Island..?”
The following maps were gathered from various sources with the intent of making one point. Throughout the ages Japanese national maps prove Dokdo was not considered an inherent part of Japan as their Foreign Ministry now boldly claims. For reference, Oki Island has been boxed and a modern map at the top gives a geographical reference point for the viewer. From these maps, it’s a logical conclusion that for centuries before the annexation of Dokdo in 1905 the Japanese considered Oki Island (隱岐) as the Northwestern boundary of Japan. For higher magnification, each map is clickable.

“..A Classic Example of a Japanese Historical Map showing Japan’s western boundary…”
To familiarize the readers of this page with what were the historical limits of Japan, here we have a case study of a typical map from this area. This chart is highly detailed and proves without a doubt, beyond the Oki Islands lie Korean territory. Boxed in blue to the upper right is Oki Island and this map ends only slightly beyond this island group. Again in blue is tiny Minoshima (見島). This shows minor islands belonging to this prefecture were indeed included and thus Dokdo was not part of Shimane prefecture.

An 1877 map of Japan's Shimane Prefecture that cleary excluded Dokdo - Takeshima from Japan.

The map above was drawn in 1877 and showed the northwestern limits of Japan indictated by the border. Oki Islands (boxed in blue upper right) was the boundary of Japan and Korea’s Dokdo Island was excluded. Tiny minor islands such as Minoshima (blue box upper left) were drawn as part of Japan.

The map of Shimane shows no islands west of the Oki IslandsDokdo Takeshima is not to be seen on this map of Japan's Shimane Prefecture

Above left: This close-up portion of the 1877 map confirms the Oki Islands as Japan’s territorial limit. Above right: A larger picture of tiny Minoshima (見島) that lies off of Japan’s West coast confirms tiny minor islands were also drawn on the map. Thus Dokdo Island was not part of Japan.
As a rule, historical Japanese maps of Shimane Prefecture and the Oki Islands omitted Dokdo Island. The maps below confirm this fact.

A Japanese map of Shimane dated 1876 that lacked Dokdo Takeshima IslandShimane Prefecture's Oki Islands were the limit of Japan as Dokdo - Takeshima was not drawn on this chart

Above left: An 1876 Japanese map showing the southern portion of Japan. Oki Islands are shown on the border of the map at the top and minor islands are included but Dokdo is not on this chart. Above right: This map dated 1878, shows Shimane Prefecture with the Oki Islands as the westernmost limit of Japan. (click maps)

Dokdo Takeshima cannot be seen on this Japanese map of Shimane Prefecture dated 1881In 1883 Japan did not draw Dokdo Takeshima (Liancourt Rocks) on this map of Shimane Prefecture

Top left: This Japanese chart, dated 1881 of Shimane and the Oki Islands did not include Dokdo although tiny Minoshima was drawn in at the bottom. Above right: An 1883 colour coded map of Shimane area and the Oki Islands drawn in red as Japan’s limit.

An 1890 map of Japan's Shimane Prefecture that lacked Dokdo (Liancourt Rocks)In 1891 this Japanese chart of Shimane also omitted Dokdo Takeshima (Liancourt Rocks)

Above maps were drawn in 1890 (left) and 1891 (right) these charts were pages from Japanese national map books. No prefecture maps in these books included Dokdo Island. Note tiny Minoshima (見島) on the lower right of each chart. (click)

An 1895 Japanese map of Shimane without Dokdo TakeshimaAnother 1895 Japanese map of Shimane without Dokdo Takeshima (Liancourt Rocks)

Above: Both of the maps above are from the year 1895 and show the Oki Islands group as the limit of Japan. The map on the right included Minoshima (見島) and thus could be said to have included minor islands. Dokdo Island was again not included on either map. (click maps)

Only five years before Japan annexed Dokdo the islands were not to be found on maps of Shimane PrefectureAn 1897 Map of Shimane Prefecture that lacked Dokdo Takeshima (Liancourt Rocks)

Above left: In 1899 this chart used appended maps to include the distant Oki Islands, however Dokdo Island was still exluded. Above right: An 1897 map of Shimane Prefecture and the Oki Islands without Dokdo. (click)

Two years before Japan seized Dokdo Island the islets were outside of Japanese territoryEven after Japan seized Dokdo this 1907 Japanese map lacked the island

Above left: Two years before Japan forcibly annexed Dokdo Island Japanese maps did not include the islands. Above right: For years after Japan’s military annexation of Dokdo, Shimane Prefecture maps still did not include Dokdo Island. This was mostly due to Japan’s failure to publicly announce her “incorporaton” in 1905.

Many post annexation Japanese maps lacked Dokdo (Liancourt Rocks)Many post annexation Japanese maps lacked Dokdo (Liancourt Rocks)

Above left: In 1908, three years after Japan annexed Dokdo, her maps failed to show the islands. Above right: Even decades after 1905, this map made in 1935 didn’t show Dokdo. At this time Korea was a colony of Japan and the residents of both countries fished the waters around Dokdo Island.

Many post annexation Japanese maps lacked Dokdo (Liancourt Rocks)Many post annexation Japanese maps lacked Dokdo (Liancourt Rocks)

Above pictures: Shockingly, both maps shown here were printed well after Japan seized Dokdo in 1917 (left) and 1941 (right) both maps included the Oki Islands group and used appended charts to include minor outlying islands that were part of Shimane Prefecture, however Dokdi was again excluded.

Japanese Ancient Maps Excluded Dokdo – Takeshima Part IV – The Only Possible Conclusion

“Japan’s MOFA’s claims are false. Dokdo was never an inherent part of Japan…”
When studying historical maps to determine past territorial perceptions, one must first collect as many charts as possible of the region in question made by the nation that created them. From there, these maps must be examined and compared to find a dominant trend. With this in mind, there can be no other conclusion that Japan excluded Dokdo Island from her land throughout history. The islets were never part of Japan.
This page is last of a four-page series. If the reader reads and observes the dozens of charts found here and on the subsequent pages, it’s possible to conclude the following: Not only did Japan exclude Dokdo from her territory, she frequently labeled and drew the islets as Korean. Thus Japan’s MOFA claims of historical title to Dokdo are simply wrong. Dokdo island is not, and was not an inherent part of Japan.
