For nearly 60 years, a World War II mine has rested at the bottom of the Kammon Straits in western Japan. Officials from the Japanese Maritime Self-Defense Force made the discovery of the bomb in June. Japanese officials believe a U.S. bomber with the Allied Forces may have dropped the mine near the close of the Pacific war.
The MSDF detonated the mine early in the morning on August 13, after moving it further out into the sea. No one was harmed when the mine exploded.
The MSDF says about 4,500 mines may have been dropped in the Kammon Straights during the war which could mean more discoveries like this one.
