Tokyo’s rebound became a surge.
Now earnings must justify it.

Closing Bell

Tokyo turned an early rebound into a decisive close. The Nikkei 225 gained 2,091.07 points, or 3.26%, to 66,232.19. It closed at the day’s high after opening at 64,544.05 and touching 64,203.47. The broader TOPIX rose 95.74 points, or 2.44%, to 4,014.95. The finish converted a tentative post-holiday bounce into one of the largest point gains in the index’s history.

Volume on the Prime Market was about 2.322 billion shares. Thirty-one of the 33 industry groups advanced, and roughly four-fifths of Prime listings rose. This was broader than an index-heavyweight squeeze, even though a few large technology names supplied an extraordinary share of the Nikkei’s point gain.

How the Day Changed

The first phase was repair. Tokyo reopened after Marine Day following a 6.4% weekly decline and a 4.03% fall on Friday. Investors bought shares that had been liquidated most aggressively, encouraged by stabilization in U.S. semiconductor stocks and a strong technology rebound in South Korea.

The second phase was acceleration. The Nikkei moved from an intraday low of 64,203.47 to a 66,232.19 close—a rise of more than 2,000 points from the low—and ended without surrendering any of the final advance. That high close matters: buyers did not merely fill the opening gap; they increased risk into the bell.

Yet the day should be read against the scale of the preceding damage. A one-session jump can reflect improving conviction, forced short covering and the violence of the earlier selloff at the same time. It restores price, not automatically trust.

Today’s Market Mover: Kioxia

Confidence: High

Kioxia Holdings (285A) climbed 17.18% to ¥61,060, leading the Nikkei by percentage and dominating Prime Market turnover. The memory-chip company became the clearest expression of the session’s bargain hunting after falling 16.1% on July 17 and 32.3% over the prior week.

Kioxia’s rebound was joined by Ibiden, up 11.03% to ¥17,415, and Socionext, up 9.11% to ¥2,472.50. Advantest contributed roughly 513 points to the Nikkei’s advance; SoftBank Group, Kioxia, Fast Retailing and Tokyo Electron were also major positive contributors. The result was a technology-led rally with unusually large index leverage.

Winners, Laggards and Breadth

Gains spread well beyond chips. Mining, insurance, oil and coal products, nonferrous metals, other financials and banks led the industry table. Rising long-term yields supported the earnings narrative for lenders, while elevated energy prices favored resource-linked shares.

The laggards showed that the market was not indiscriminate. Nintendo fell 4.13% to ¥6,993, Kikkoman lost 2.49% to ¥1,625.50 and CyberAgent declined 2.36% to ¥1,448.50. Only “other products” and fishery/agriculture/forestry finished lower among the 33 sectors.

Yen Watch

USD/JPY remained around 162.5 in the Asian session. That level helps exporters translate overseas earnings into yen, but it also raises the domestic cost of fuel, food and industrial inputs. Near four-decade weakness keeps intervention risk alive and complicates the idea that yen depreciation is simply positive for stocks.

The currency barely strengthened even as Japanese equities surged. That divergence suggests the equity move was chiefly a repricing of oversold risk rather than a broader vote of confidence in Japan’s macro balance.

Rates and JGB Watch

The 10-year Japanese government-bond yield traded around 2.73%, after reaching 2.90% earlier in July. Oil-driven inflation anxiety, heavy government borrowing, fiscal-policy uncertainty and questions about the Bank of Japan’s path continue to keep term yields elevated.

That matters for equities in two directions. Banks can benefit from higher rates and a steeper curve, but richly valued growth stocks face a higher discount rate. Tuesday’s simultaneous rise in technology and bank shares was possible because the starting point was a severe selloff; it does not eliminate that longer-term valuation tension.

Oil, Geopolitics and the Global Handoff

Brent crude remained near the high-$80s a barrel after briefly exceeding $91 on Monday as the U.S.–Iran conflict and shipping risk dominated global markets. For resource-poor Japan, oil is simultaneously a corporate-cost shock, a household-inflation shock and a trade-balance risk.

Tokyo’s message to Europe and the United States is therefore conditional. Investors were willing to buy technology after a liquidation, but the next leg depends on whether oil stabilizes and whether U.S. technology earnings validate exceptional AI capital expenditure. Alphabet, Tesla and Intel results are the immediate test.

Policy / BOJ Watch

The Bank of Japan’s July 30–31 meeting now sits directly behind the market’s weak-yen and high-yield debate. The policy rate has stood at 1.0% since June. Officials must weigh imported inflation and currency weakness against the risk that tighter conditions reinforce volatility in government bonds and growth shares.

Prime Minister Sanae Takaichi’s new economic roadmap targets more than ¥370 trillion in combined public and private investment through fiscal 2040. Its growth ambitions are significant, but bond investors are focused on fiscal credibility and the explicit preservation of central-bank independence.

Publisher’s Market Note

Tuesday was not a weak technical bounce. A 3.26% high close, 31 rising sectors and nearly ¥10 trillion of Prime Market turnover constitute a serious recovery session. But it was also a rebound from exceptional damage. The cleanest conclusion is narrower: forced selling eased, buyers returned with size, and semiconductors regained leadership for one day.

The next evidence must come from earnings, not price momentum. If U.S. technology results justify spending, Kioxia’s rebound can become part of a fundamental rerating. If they do not, the same concentration that lifted the Nikkei today can reverse it quickly.

Before the Next Open

• Whether U.S. technology earnings validate AI investment and semiconductor demand.
• Whether Kioxia and other chip leaders hold Tuesday’s gains instead of retracing them.
• Whether Brent remains below $90 or geopolitical headlines revive the inflation shock.
• Whether USD/JPY above 162 produces stronger intervention warnings.
• Whether the 10-year JGB yield breaks higher from the 2.7% area.
• Whether banks and cyclical shares continue broadening the rally beyond technology.
