Japan's answer to the Maldives sandbank, and almost nobody outside Japan has heard of it. Good reef snorkelling and turtles around the island. Kume-jima was a stopover on the Ryukyu Kingdom's China trade route and retains Ryukyu-era stone villages and the Tatami-ishi, a shore of naturally pentagonal basalt slabs. The island also hosts a deep-seawater research facility drawing 612m water for aquaculture, an unlikely piece of ocean engineering. Anchorage: Anchor off in 3-12m sand and tender to the bar. Kume-jima's harbours give shelter. Hazards: The sandbar submerges on the flood, know the tide, and never leave anyone on it. Typhoons Jul-Oct. Mehr
