Tokyo:A Japanese Maritime Self-Defense Force (SDF) submarine collided with a commercial vessel in the Pacific Ocean off the western main island of Shikoku, injuring three crewmembers on the submarine, the Defence Ministry said on Tuesday.
In the incident on Monday, the 84-metre-long Soryu scraped the hull of the vessel when it was surfacing, Xinhua news agency quoted the Ministry as saying.
Government spokesman Katsunobu Kato told reporters here that the accident occurred off Cape Ashizuri in Shikoku's Kochi prefecture.
When contacted by Japan's Coast Guard, crew on the commercial ship said they did not feel the impact and the vessel did not appear to have sustained any damage, Kato added.
