Nikkei 225 Falls 1.4% as Middle East Tensions Weigh on Risk Assets
The Nikkei 225 declined 1.38% to close at ¥38,547 equivalent (EWJ $85.29) on Monday, April 5, 2026, as escalating Middle East tensions prompted a broad risk-off sentiment across Tokyo markets. The broader TOPIX index fell a more modest 0.57% to ¥2,743 equivalent, suggesting selective selling pressure concentrated in large-cap names.
The yen strengthened modestly against the dollar, with USD/JPY rising 0.45% to ¥173.79, continuing to trade near multi-decade highs. While the weaker yen typically benefits Japanese exporters by boosting overseas earnings when repatriated, geopolitical uncertainty overshadowed currency tailwinds as investors sought safer havens.
Market sentiment was dampened by overnight developments in the Middle East, including reports of Iranian drone strikes on Kuwaiti oil infrastructure and attacks on Israel-linked vessels in the Strait of Hormuz. The escalating tensions between Iran and Israel, combined with U.S. diplomatic pressure ahead of unspecified deadlines, created a risk-averse environment that weighed heavily on technology and financial stocks.
SoftBank Group led declines among major names, tumbling 3.89% to ¥2,068 as investors rotated away from high-beta technology plays. Industrial automation giant Fanuc dropped 3.51% to ¥3,930, while Mizuho Financial Group fell 2.63% to ¥1,851 as banking stocks faced pressure from safe-haven flows. Gaming heavyweight Nintendo declined 2.39% to ¥3,150, and electronics manufacturer Kyocera rounded out the major losers with a 2.16% drop to ¥3,500.
Sony Group bucked the broader trend, managing a modest 0.09% gain to ¥4,800, likely supported by its diversified entertainment portfolio and recent strength in its gaming and content divisions. The resilience in Sony shares highlighted selective buying interest in defensive growth names even amid the broader market weakness.
The session’s decline comes as Japanese markets continue to navigate elevated geopolitical risks while domestic economic fundamentals remain relatively stable. With the Bank of Japan maintaining its accommodative stance and NISA investment flows providing underlying support for equity markets, many analysts view the current weakness as primarily driven by external factors rather than domestic concerns.
Looking ahead, investors will be closely monitoring developments in the Middle East for signs of further escalation, while also watching for any potential intervention by Japanese authorities if yen weakness accelerates beyond current levels. The combination of geopolitical uncertainty and currency volatility is likely to keep markets on edge in the near term.
