Japanese Prime Minister Shigeru Ishiba has decided to resign, public broadcaster NHK reported Sunday, citing unidentified sources.
NHK did not immediately provide details on the timing of the resignation or the reasons for Ishiba's decision. There was no immediate comment from the prime minister's office or from the ruling Liberal Democratic Party (LDP) when the report was published.
Ishiba, a veteran lawmaker and long-standing figure in the LDP, has held prominent roles in government for decades. His career has included senior party positions and cabinet posts, and he has been a prominent voice in debates over defense and administrative reform. The LDP has been Japan's dominant party for much of the postwar era, and changes in its leadership typically have immediate consequences for the premiership because the party leader of the majority in the Diet is usually elected prime minister.
Japanese political procedure requires that a prime minister be elected by the National Diet. In practice, that means the LDP's selection of a new leader would set the path for choosing a successor to serve as prime minister. The timing of any LDP leadership vote and the process that will follow were not detailed in NHK's report.
Domestic and international observers routinely watch leadership changes in Tokyo for potential effects on economic policy, defense posture and relations with key partners including the United States, China and regional neighbors. Ishiba's resignation announcement comes amid an era of heightened attention to security issues in East Asia and ongoing economic challenges at home.
NHK's report was carried by other outlets following the broadcaster's bulletin. The prime minister's office and the LDP office were not immediately available for comment, and no schedule for a formal resignation or an official announcement was provided in the initial reporting.
Further developments, including any formal statement by Ishiba, the timing of his departure and the LDP's internal response, are expected to be reported as more information becomes available. Government officials and party representatives customarily issue detailed explanations and procedural timetables in the hours and days after such a decision is announced.
This report will be updated as additional, confirmed details emerge from official sources and parliamentary channels.
