Guam's lieutenant governor on Wednesday urged Japanese people to visit the Pacific island despite North Korea's threat to fire missiles near the U.S. territory, saying Washington has prepared for any contingency.

"All the defenses are already in place" such as the Aegis missile defense system, Raymond Tenorio told a news conference at the Foreign Correspondents' Club of Japan in Tokyo. "Come to Guam" because it is a "safe place to come."

Tenorio made the remarks as speculation is rife that Guam may see a decline in tourism following Pyongyang's announcement earlier this month that it is contemplating launching a missile strike against the U.S. Pacific territory.
