Tokyo Stock Market Today (Nov 20, 2025): Nikkei 225 Soars on Nvidia AI Rally, Weak Yen and Stimulus Bets

Tokyo, November 20, 2025 — Japan’s stock market roared back to life on Thursday as a powerful global tech rebound, led by Nvidia’s blockbuster earnings, combined with a weaker yen and expectations of a massive fiscal stimulus package to send the Nikkei 225 sharply higher.

At the close, the Nikkei 225 jumped 1,286.24 points, or 2.65%, to 49,823.94, snapping a four‑day losing streak. The broader TOPIX climbed 53.99 points, or 1.66%, to 3,299.57. ^[1]

The rally was broad-based, with AI-linked chip stocks, exporters and financials all advancing, even as Japan’s government bond market flashed warning signs about rising yields and swelling debt.

Key Market Snapshot: Nikkei Reclaims the 50,000 Line Intraday

Buying started aggressively from the opening bell after Nvidia delivered another blowout quarter and bullish guidance, easing fears that the global AI trade had run too far, too fast. ^[2]

Intraday move:
- Nikkei 225 surged as much as around 4% in early trade, trading above the key 50,000-point psychological line, with intraday highs reported in the 50,300–50,500 range before gains moderated into the close. ^[3]
- TOPIX also spiked more than 2% at its morning peak. ^[4]
Closing levels:
- Nikkei 225: 49,823.94 (+2.65%)
- TOPIX: 3,299.57 (+1.66%) ^[5]

Reuters and local media highlighted that the Nikkei briefly moved above the “psychological” 50,000 level before easing slightly in afternoon trade, but still posted its strongest one-day gain in weeks and ended four straight sessions of losses. ^[6]

Market breadth underlined the strength of the move: advancers outnumbered decliners 186 to 38 on the Nikkei, indicating buying interest across sectors rather than a narrow tech rebound. ^[7]

Nvidia’s “Flawless” Earnings Spark Global AI Relief Rally

The main catalyst came from overnight U.S. earnings:

Nvidia reported record quarterly revenue of about $57 billion and forecast an even stronger next quarter, comfortably beating Wall Street expectations and pushing its shares more than 4–5% higher in after-hours trading. ^[8]
Analysts described the results as “virtually flawless” and a reassurance that AI infrastructure spending remains robust, easing fears of an AI bubble that had weighed heavily on global tech stocks in recent sessions. ^[9]

That relief quickly rippled across Asia:

A regional tech-led rally lifted markets in Japan, South Korea and Taiwan, with chipmakers and AI-related names leading gains. ^[10]
Global investors also took comfort from signs that Washington may delay some planned semiconductor tariffs, easing near-term pressure on the sector. ^[11]

For Tokyo specifically, the Nvidia news was doubly powerful: many of the Nikkei’s biggest movers sit deep in the AI supply chain, from chip testing to advanced materials, meaning upbeat guidance in the U.S. translates directly into higher earnings expectations in Japan.

Weak Yen and Giant Stimulus Expectations Add Fuel to the Rally

Beyond AI, local macro dynamics provided a major tailwind:

The U.S. dollar climbed into the “upper 157 yen” area, pushing the yen to around a 10‑month low, as traders bet that Japan’s fiscal stance will become even more expansionary. ^[12]
MUFG and other strategists noted that USD/JPY hit roughly 157.7, fully unwinding the yen’s gains from earlier in the year and underscoring its clear underperformance against other major currencies. ^[13]

A weaker yen tends to boost shares of exporters by inflating overseas earnings when converted back into yen, and by improving Japan Inc.’s competitiveness abroad.

At the same time, the currency move is being driven less by the Bank of Japan and more by looming fiscal expansion:

NHK and other outlets, cited in MUFG’s FX note, reported that the government is putting the finishing touches on an economic package worth around ¥21.3 trillion, with about ¥17.7 trillion in general-account spending. ^[14]
Analysts worry that such a large supplementary budget could mean significantly higher bond issuance, amplifying concerns about Japan’s already fragile fiscal position. ^[15]

Those twin forces — yen weakness and stimulus hopes — helped support:

Export-oriented blue chips, including automakers and industrials. ^[16]
Financials and real estate stocks, which often benefit from steeper yield curves and expectations of stronger nominal growth. ^[17]

However, they also raised red flags in the bond market (more on that below).

Sector Highlights: Tech, Real Estate and Banks Lead the Charge

Data from Investing.com and Reuters show that Thursday’s rally was broad but particularly intense in AI, real estate and banking. ^[18]

Best-performing sectors

Real Estate: One of the top-performing groups on the Tokyo Stock Exchange, reflecting optimism that lower real yields and stronger nominal growth will support property values. ^[19]
Banking: Benefited from steepening yield curves and hopes of stronger loan demand amid stimulus and ongoing economic support. ^[20]
Textiles & Consumer-related names: Also saw strong buying, as investors rotated back into domestic cyclicals that had been hit during the recent risk-off phase. ^[21]

Major individual movers on the Nikkei 225

According to market data:

Sumitomo Dainippon Pharma jumped about 10.8%, leading gains on the Nikkei by percentage terms. ^[22]
Sompo Holdings surged roughly 10.5% after announcing a share buyback of ¥77 billion, making it one of the day’s standout winners and underscoring strong shareholder-return themes in Japan. ^[23]
Advantest, a key chip-testing equipment supplier and a bellwether for AI infrastructure demand, climbed close to 9%, reflecting renewed confidence in the sector after Nvidia’s results. ^[24]

In early trading, the rally was even more dramatic among AI-linked heavyweights:

SoftBank Group soared around 9%, while Tokyo Electron and Ibiden each advanced more than 7% at one point in the morning session. ^[25]

Notable laggards

Despite the upbeat tone, some stocks bucked the trend:

Tokio Marine Holdings fell nearly 8%, making it one of the biggest decliners on the Nikkei by the close. ^[26]
Shiseido dropped about 5%, extending recent underperformance in some consumer and cosmetics names. ^[27]
Tokyo Electric Power (TEPCO) slid almost 4%, after local media reported concerns over mishandling of confidential documents as the utility seeks to restart the Kashiwazaki–Kariwa nuclear plant — a reminder that idiosyncratic risks can still overshadow the macro narrative for individual stocks. ^[28]

Market volatility remained elevated, with the Nikkei Volatility Index rising to around 36.5, up roughly 3.6% on the day — signaling that, although prices bounced strongly, investors are still willing to pay up for downside protection. ^[29]

Bond Market Flashing Red: Yields at Highest Levels Since 2008

In stark contrast to the euphoria in equities, Japan’s government bond market is under heavy pressure:

The 10-year JGB yield climbed above 1.8%, its highest level since the global financial crisis in 2008, according to live market commentary. ^[30]
MUFG notes that both 10-year and 30-year JGB yields jumped roughly 6–7 basis points at one stage, with the 30-year yield on track for an 11th straight day of increases — an unusually long streak in Japan’s historically placid bond market. ^[31]

Analysts say the sell-off reflects:

Growing unease about the size of Prime Minister Sanae Takaichi’s planned stimulus, expected to exceed ¥20 trillion, and the corresponding increase in debt issuance. ^[32]
Fears that ultra-loose monetary policy and aggressive fiscal expansion could undermine long-term confidence in Japan’s public finances while keeping the yen under persistent pressure. ^[33]

Japanese officials have expressed concern about the pace of the currency move but have so far stopped short of signaling imminent FX intervention, suggesting that verbal warnings alone may not yet be enough to stem speculative yen selling. ^[34]

Global Backdrop: Fed Uncertainty and U.S. Data Delays

Thursday’s Tokyo surge came against a complex global macro backdrop:

U.S. stocks broke a four-day losing streak overnight, with the S&P 500 up about 0.4% and the Nasdaq up 0.6%, ahead of Nvidia’s report. ^[35]
Minutes from the Federal Reserve’s latest meeting revealed that many policymakers favor a pause on further rate cuts in December, even as inflation remains above target — prompting markets to scale back expectations for additional easing this year. ^[36]
The U.S. jobs data calendar has been thrown off after the October nonfarm payrolls report was cancelled and folded into the November release, now delayed until December 16, after the Fed’s next policy meeting. That leaves the central bank with less visibility on the labor market when it decides on rates on December 10. ^[37]

Those developments helped the U.S. dollar index climb back above the 100 level, reinforcing upward pressure on USD/JPY and contributing to the supportive environment for Japanese exporters. ^[38]

What Today’s Rally Means for Investors

For domestic and international investors watching the Tokyo stock market today, several big themes stand out:

AI Trade Still in the Driver’s Seat
Nvidia’s results have, at least temporarily, validated aggressive global AI spending plans. Tokyo’s surge shows that Japan remains a key leverage point on the AI value chain — from chip equipment (Advantest, Tokyo Electron, Ibiden) to data-center infrastructure (Fujikura) and venture-heavy groups like SoftBank. ^[39]
Currency and Fiscal Policy Risks Are Climbing
The combination of a weak yen, multi-decade-high bond yields and a giant stimulus package is unusual for Japan. It supports equity earnings in the short term but raises questions about:
- How long the BOJ can maintain ultra-easy policy as yields climb.
- Whether further yen weakness risks triggering intervention or domestic political backlash. ^[40]
Market Breadth Suggests More Than Just Short-Covering
With well over 100 more rising than falling names on the Nikkei, and gains stretching from tech to real estate, banks and cyclicals, today’s move looks broader than a simple short squeeze — though elevated volatility shows sentiment remains fragile. ^[41]
Key Events to Watch Next
- Details of Takaichi’s stimulus package, expected soon, including how much will be funded via long-dated JGBs. ^[42]
- The Fed’s December meeting and the delayed U.S. jobs data, which could reshape the global rate outlook and dollar trajectory. ^[43]
- Any shift in tone from Japanese authorities on FX intervention if USD/JPY continues to push towards levels that previously triggered action. ^[44]

For now, though, November 20, 2025 will be remembered as “Nvidia day” in Tokyo — the session when AI optimism, a soft yen and stimulus expectations combined to send the Nikkei vaulting back towards the 50,000 mark.
