The extension beyond the scheduled Sept. 30 expiry is in response to a UN Security Council decision in July to extend a military observer mission to Nepal until Jan. 23.
Japan has sent six Self-Defense Forces officers to Nepal since March 2007 to participate in the U.N. Mission in Nepal (UNMIN), a special mission to help the peace process in the country.
UNMIN was established in January 2007 and the UN Security Council extended UNMIN´s mandate for six months for a third time on Jan. 23 this year.
