Seemingly against all odds, the Aniva Lighthouse stands atop this rocky outcrop where it once lit the way for vessels navigating the fierce currents, hidden rocks, and frequent fogs of Cape Aniva on the island of Sakhalin. Russia"s largest island, Sakhalin lies off the mainland"s Far East coast, due north of the Japanese island of Hokkaido. The island was hotly contested by both Russia and Japan in the 19th and early 20th centuries. In the late 1930s, when the Aniva Lighthouse was built, Russia controlled the northern half of Sakhalin while Japan controlled this, the southern part—so it was a team from Japan that built this lighthouse.
