North Korea carried out a new missile test in recent days, one in a continuing series of launches this year that has kept neighboring Japan and South Korea on alert. Japanese Prime Minister Sanae Takaichi's office said she issued instructions to her government early on October 12 in response to a suspected ballistic missile launch, according to a statement from the prime minister's office, the second such instruction this month following a similar episode on October 3.
Takaichi became Japan's first woman prime minister when she took office on October 21, 2025, succeeding Shigeru Ishiba after winning the Liberal Democratic Party's leadership contest and forming a coalition government with the Japan Innovation Party. Her government has made national security and missile defense a visible priority, and she has continued a practice established by her predecessors of issuing rapid public instructions to relevant ministries whenever North Korean launches are detected, a protocol meant to reassure the public that the government is monitoring the situation in real time.
North Korea's missile program has continued through changes in both the South Korean and Japanese governments in recent years, with launches ranging from short-range systems to longer-range missiles that have at times passed over or near Japanese territory, prompting evacuation alerts in affected areas. Pyongyang has described its missile and weapons programs as necessary for its own defense given the presence of United States and allied forces in the region.
Japan's response today was limited to the instructions from the prime minister's office rather than any broader military action, consistent with the pattern of recent years in which Tokyo closely tracks launches, coordinates information-sharing with Washington and Seoul, and raises the matter through diplomatic channels without seeking to escalate the situation militarily.
Watch for any additional detail from Japan's Ministry of Defense on the type and trajectory of the missile, and for coordination statements from South Korea and the United States.
