Far fewer boats than Cape Maeda. Ie-jima was the site of ferocious fighting in April 1945 and is where the war correspondent Ernie Pyle was killed, a monument marks the spot. The island's Mount Gusuku is a sacred site with a summit shrine, and the surrounding reefs were left largely undived until the 1990s. Anchorage: Anchor in the lee of Ie-jima or Minna-jima, good shelter depending on wind. Hazards: Strong current on the outer walls. Typhoon season Jul-Oct. Mehr
