Fifteen remain missing as questions grow as to why the Kazu I sailed in rough weather off the hazardous Shiretoko peninsula

Rescuers searching since a tour boat carrying 26 people apparently sank off far north-eastern Japan have found the body of an 11th victim – a child – as questions intensify about why the vessel sailed in rough weather at a known hazardous location.

The child was found late Sunday and later confirmed dead, the coast guard said Monday. The bodies of 10 victims – seven men and three women – were found earlier Sunday.
