The day was dominated by a tsunami advisory for Japan's Pacific coast, from Ibaraki to Okinawa, following a magnitude 7.8–8.2 earthquake off the Philippines. NHK, TBS, and Yomiuri provided rolling updates on evacuation orders, observed waves up to 20 cm, and meteorological agency press conferences. The advisory was lifted by late afternoon. Simultaneously, the Nikkei average plunged over 2,500 yen, driven by US rate hike fears cooling AI enthusiasm, marking the second-largest drop this year. Nikkei and NHK tracked the sell-off throughout the trading day. In politics, Prime Minister Takaichi denied involvement in a defamatory video scandal from the 2025 LDP presidential race, while a cross-party agreement on male-line imperial succession was reported. A data breach at two Hokkaido hospitals potentially exposed 510,000 patient records.
