Nikkei 225 Surges 1.58% as Weak Yen Lifts Tech Stocks

The Nikkei 225 climbed 1.58% to ¥41,546 on Monday as a weaker yen provided tailwinds for Japan’s export-heavy technology sector, with industrial robot maker Fanuc leading gains amid renewed optimism about global manufacturing demand.

Yen Weakness Drives Export Rally

The USD/JPY pair strengthened to ¥157.73, marking another test of levels that have previously triggered intervention concerns from Japanese authorities. This yen weakness proved particularly beneficial for technology exporters, with Fanuc Corp surging 2.93% to ¥3,109.44 as investors bet on improved overseas earnings when converted back to yen. Sony Group also participated in the tech rally, advancing 1.40% to ¥3,763.56.

The currency dynamic created a clear sector rotation, with domestic-focused automakers underperforming despite their export exposure. Toyota Motor declined 1.01% to ¥28,675.42, while Honda Motor fell 0.85% to ¥4,953.30, suggesting investors remain cautious about the automotive sector’s near-term prospects amid global economic uncertainty.

Financial Sector Shows Resilience

Japan’s major banking groups demonstrated strong performance, with all three megabanks posting gains. Mizuho Financial led the charge with a 1.21% increase to ¥1,720.62, followed by Mitsubishi UFJ Financial’s 0.88% rise to ¥3,605.56. The banking sector’s strength reflects growing expectations that the Bank of Japan may need to adjust its ultra-accommodative stance sooner than previously anticipated, potentially benefiting net interest margins.

SoftBank Group bucked the broader market trend, declining 0.87% to ¥3,251.64, as investors continued to digest the conglomerate’s complex portfolio positioning amid volatile global technology valuations. The mixed performance in tech-adjacent names highlighted the market’s selective approach to risk assets.

BOJ Policy Outlook Remains Key

With the next Bank of Japan meeting scheduled for April 28, 2026, market participants are closely monitoring Governor Ueda’s communications for signals about potential policy adjustments. Current market expectations center on a hold at the current rate, though attention will focus on the central bank’s tone regarding US-China trade tensions and their impact on Japan’s export-dependent economy. Any dovish signals could further pressure the yen, while unexpected hawkish commentary might provide currency support.

Monday’s session underscored the continued importance of currency dynamics in driving Japanese equity performance, particularly as the yen approaches levels that have historically prompted government intervention. For NISA investors, the technology sector’s outperformance offers opportunities in globally competitive Japanese companies, though the sustainability of yen-driven gains remains dependent on broader monetary policy trajectories and international trade developments.
