"No Trespassing" Sign - Posted by Japanese Government

The island of Iwo Jima is located 660 nautical miles south of Tokyo.  One of three groups of islands comprising the Nanpo Shoto (an island  chain extending 750 miles south of the Tokyo-Bay entrance to approximately 300 miles of the Marianas), Iwo (like the other islands of this chain) came under Japanese control in the late-nineteenth century. 

By 1891, Iwo Jima was administered as part of Japan.  As Japanese people began to colonize the islands, the government banned foreign settlers.  This sign on Iwo Jima, which is dated 1937, reflects that ban.
