This was a map published for motorists in each prefecture. Insert maps show the milepost in Shimane Prefecture, Matsue, the prefectural capital, and the Oki Islands. But there is no marking of Dokdo in the map of the Oki Islands. This implies that the Japanese government did not consider Dokdo as Japanese territory even though it had illegally annexed the islet into Shimane Prefecture in 1905.
