On Friday, February 2, news emerged that a massive oil slick, believed to be leaking from the sunken Iranian tanker Sanchi, has now reached the southern shores of Japan. A Japanese coast guard official informed Reuters in a phone conversation that the large oil mass has currently reached Amami-Oshima Island, which is part of a chain of islands known as Okinawa, famous for its clean waters and untouched beaches. According to him, officials are currently investigating whether this oil pollution is related to the Sanchi tanker. The Sanchi tanker, registered in Panama and managed by Iran, sank about three weeks ago, but concerns about the environmental damage from this incident continue to persist. The Sanchi tanker, carrying oil and gas condensate to South Korea, collided with the cargo ship Crystal on January 6 and sank in the East China Sea. All 32 crew members of the Sanchi, including 30 Iranians and two Bangladeshi nationals, were killed in the incident. Only the bodies of three crew members have been found. The Sanchi tanker had a capacity of about 85 tons and its wreckage lies at a depth of 115 meters. China has sent an underwater robot to investigate the situation. Following this incident, over 70 vessels have been engaged in cleaning up oil spills in an area of 330 square kilometers. The unnamed Japanese coast guard official told Reuters on Friday that the Japanese Prime Minister's Office has been forced to form a special unit to coordinate efforts to deal with this pollution on its shores. To fully determine whether this oil mass originates from the Sanchi, officials intend to compare samples taken from this mass with samples of oil leaked from the Sanchi tanker.
