The Japan Coast guard said four people were found unconscious early Sunday in the area around Hokkaido’s Shiretoko Peninsula where a tourist boat with 26 people aboard went missing a day earlier. The boat Kazu I reported to the coast guard it was taking on water around 1:15 p.m. Saturday, and then told its operator that it was tilting 30 degrees around 2 p.m. before losing contact off Japan’s northernmost main island, the JCG said. Twenty-two adult passengers and two children were aboard the boat along with two crew.
