The first item on Prime Minister Junichiro Koizumi's agenda when he meets with North Korean leader Kim Jong Il will be his demand for information about 11 Japanese believed abducted to the Stalinist state between 1977 and 1983, Chief Cabinet Secretary Yasuo Fukuda said Monday.

Koizumi and Kim are to hold their historic summit in Pyongyang on Tuesday.

"It is the highest matter of concern, and the issue is one of the security of the country and its people," Fukuoda told reporters at Koizumi's office in Tokyo after meeting with relatives of the missing.
