On the 5th, Prime Minister Sanna Takii of Japan condemned Iran's actions during a telephone conference with German Chancellor Olaf Scholz. She highlighted Iran's attacks on civilian facilities, including critical energy infrastructure, resulting in civilian casualties. The Japanese government disclosed this stance after the discussions took place.

In her communication, Takii emphasized that the attacks by Iran extend beyond military targets to include civilian and diplomatic sites, raising significant concerns about the safety of civilians in the affected areas. Furthermore, she also conveyed her condemnation to the UAE's Minister of Industry and Advanced Technology, Sultan Al Jaber, during a separate meeting the same day, reinforcing Japan's position on the matter in the context of international security.

Despite strongly denouncing Iran's actions, Takii refrained from offering legal assessments regarding the military responses by the United States and Israel. This measured approach indicates Japan's diplomatic strategy of balancing its condemnation of Iran while being cautious about getting involved in the complex geopolitical dynamics of the Middle East.
