The government ordered the Maritime Self-Defense Force (MSDF) to chase an unidentified submarine that was spotted in Japan's territorial waters around southwestern Okinawa Prefecture Wednesday morning, a government spokesman said.
The submarine subsequently left Japan's territorial waters, but the MSDF remains on full alert in case it intrudes into territorial waters again, Chief Cabinet Secretary Hiroyuki Hosoda told a news conference.
"It's extremely regrettable. We need to clarify the purpose of the intrusion and the nationality of the submarine among other questions," Hosoda said.
Crewmembers of an MSDF P3C anti-submarine patrol aircraft spotted the submarine in seas off Miyako and Ishigaki islands, southwestern Okinawa Prefecture, early Wednesday morning. At 8:45 a.m., Defense Agency Director General Yoshinori Ono ordered the MSDF to chase the submarine after receiving approval from Prime Minister Junichiro Koizumi.
