Ishinomaki port, Miyagi prefecture, Japan - Boats rest on a pier at Ishinomaki port, in Miyagi prefecture, on 15 April, more than a month after a tsunami devastated large areas of northeastern Japan. Ishinomaki was one of the most seriously affected cities in the region, hit by several waves of up to 10 meters high. All Japan’s harbors were closed briefly after the tsunami; those in the disaster zone reopened to limited shipping traffic only at the end of March.
