Japanese media on July 31 primarily shifted focus to evolving US tariff agreements. Early reports detailed a US-South Korea trade deal, outlining a 15% tariff on imports and South Korea's commitment to $350 billion in US investment. Concurrently, the Bank of Japan held interest rates steady, raising inflation forecasts while considering tariff impacts, and Fujitsu accelerated quantum computer development for economic security. By late morning, attention broadened to a US-Japan tariff agreement, with BOJ Governor Ueda deeming it "significant progress" and maintaining a rate hike stance. Other Southeast Asian nations also moved to finalize US tariff deals. In a significant development from previous days, all tsunami advisories issued after the July 30 event were lifted by mid-morning. Political speculation concerning Ishiba's leadership continued as a background narrative, alongside a new report on a potential delay for 15% auto tariffs.
