Immediately after the death of North Korean leader Kim Jong Il was announced, Prime Minister Yoshihiko Noda on Monday told his administration to "take all possible measures to prepare for the unexpected."

The prime minister also ordered the government to collect information on developments inside the North and share information with other countries, including the United States, South Korea and China.
