Japanese officials stated that they formally requested the U.S. military to ground its planes for investigation, expressing concern over the continued operation of Osprey military aircraft in the country. This request follows a recent incident where a U.S. Air Force Osprey crashed into Japanese waters, resulting in at least one crew member's death and seven others missing. Despite Japan grounding its own Ospreys and requesting U.S. forces to suspend non-emergency flights, the Pentagon claimed it had not received any official request.
