On Thursday, Japanese stock markets faced a downturn, with the Nikkei 225 index declining by 1.06% and the broader Topix index falling 1.19%. This decline follows a previous session's drop and is primarily driven by increasing oil prices and heightened concerns regarding tensions between the United States and Iran. Reports indicate that the US may consider additional actions against Iran, raising alarms for Japan, which heavily relies on oil imports from the Middle East. Additionally, the US Federal Reserve's decision to keep interest rates unchanged, despite some dissent among policymakers, contributed to global market uncertainties. Domestically, Japan's industrial production unexpectedly decreased in March, although retail sales performed better than expected. Major corporations, including Advantest, Fujikura, Mitsubishi UFJ, Mitsubishi Heavy, and Hitachi, saw significant losses, further dragging the market down.
