Four Japanese coastguard officers are expected in Hong Kong today to question the captain and crew of an Israeli container ship believed to have collided with a Japanese vessel at sea, killing seven fishermen. The officers will also inspect the Israeli-registered Zim Asia for signs of the collision with the Japanese fishing boat off northern Japan eight days ago. All but one of the fishermen on board the Shinsei Maru No3 were killed when it capsized following the collision about 40km off the Cape of Nosappu in Hokkaido. The Marine Department says the Israeli ship is scheduled to arrive in Hong Kong at around 5.30am. The investigators are expected to remain in Hong Kong for three days. The Japanese deputy consul-general, Mikio Numata, said the Japanese consulate would need to obtain the approval of the Hong Kong and Israeli governments before the investigators could board the Zim Asia. Calls to the Israeli consulate in Hong Kong went unanswered yesterday, as it was a public holiday in Israel. The Marine Department said it was not involved in the case. A spokesman for the Ministry of Foreign Affairs said his office had not been contacted about the impending arrival of the Japanese officers or their plans. The Israel Corp, which owns the Zim Asia, has apologised and offered compensation to the families of the fishermen killed. The Zim Asia's captain denies responsibility for the incident. Israel Corp chairman Idan Ofer said on Monday in Tel Aviv that the captain did not notice the accident nor hear a distress call afterwards. Mr Ofer said the company would co-operate with the Japanese authorities and investigators. Mr Numata said: 'We received information from the Israeli government that they have already decided to send someone here, but I do not know how many people they will be sending.'
