21.07.2026 ⇢ The Day Japan's First 40-Degree Extreme Heat Day Was Recorded
⌨

The morning headlines focused on the Ministry of Defense's confirmation that Chinese and Russian naval vessels conducted live-fire drills within Japan’s EEZ near Okinotorishima, marking the first such public disclosure. Simultaneously, editors tracked a historic heatwave as Gifu and Aichi prefectures became the first to record temperatures exceeding 40°C, officially designated as "Extreme Heat Days" (Kokushobi). By midday, economic coverage shifted to the "Basic Policy Shock" following the Takaichi cabinet’s approval of its inaugural economic blueprint. Market concerns over fiscal expansion triggered a government bond sell-off and pushed the yen to a 39-year low of 162.90 against the dollar. In the evening, political reporting turned to opposition criticism of Prime Minister Takaichi’s claims regarding her extreme lack of sleep and her attendance in parliament, while news of fresh U.S. strikes against Iran and President Trump's threats of retaliation provided a volatile international backdrop.
