Moneron Island, a volcanic speck roughly seven kilometers long and five wide, rises from the northeastern end of the Sea of Japan surrounded by steep cliffs where Steller sea lions haul out by the hundreds. It sits 30 nautical miles southwest of Sakhalin, the only landmass in the entire Tatar Strait, with no permanent population and no regular ferry service.
