The day was dominated by a sharp escalation in the Strait of Hormuz. By late evening, NHK and Yahoo News Japan reported Iran's Revolutionary Guard had declared a blockade, prompting the US Central Command to announce immediate retaliatory strikes. This followed days of tit-for-tat attacks on commercial shipping and US airstrikes. Through the night, outlets tracked the military exchange: TBS and Sankei detailed US strikes on 140 Iranian military sites, while Iran launched missiles at US bases. The conflict pushed other stories aside, though editors continued to monitor Typhoon No. 9's aftermath in Okinawa, extreme heat warnings across western Japan, and the opening of the Nagoya sumo tournament. Earlier, Wimbledon wheelchair tennis victories by Yui Kamiji and Tokito Oda provided a brief respite.
