Massive Selloff on Tokyo Market: What Happened?
The Tokyo Stock Exchange saw one of its biggest one-day plunges in recent memory on Friday, November 6, 2026. Panic swept through the market as investors dumped Japanese stocks, especially technology and semiconductor shares, following a sharp fall in the US tech sector overnight. Wall Street’s tech-heavy Nasdaq had tumbled 5.52%, shaking investors worldwide and leading to a huge rush for the exits in Asian markets.
Why Did the Crash Happen?
Several factors came together in a perfect storm that sent Japanese stocks sharply lower:
1. Global Tech and AI Collapse
US tech giants and companies connected to artificial intelligence hardware got hammered Thursday night. Investors worried about stricter US rules on AI and new limits on building large data centers moves that would slow down spending on new tech infrastructure. This pain spread fast to Asia when trading opened Friday morning.
Japanese firms that supply the world’s biggest chipmakers took the brunt of the selloff:
- Advantest Corp (semiconductor testing equipment) dropped 14.7%.
- Ibiden Co (chip packaging substrates) fell 16.3%.
- Kioxia Holdings (flash memory) lost 13.1%.
- Tokyo Electron (chipmaking equipment) tumbled 9.4%.
2. US Political Shift Sparks New Fears
Recent US midterm elections changed the political landscape, and markets worried it might mean tough new rules for tech and AI. Talk of moratoriums on new data centers and fresh antitrust scrutiny scared global investors. Japanese suppliers, who depend on American tech giants, were hit by uncertainty over how quickly the US would build new infrastructure.
3. Rising Wages and Rate Hike Worries in Japan
Japan’s labor ministry released new data showing wages rose faster than at any time in the last three decades. This gave traders even more reason to think that the Bank of Japan (BOJ) will hike interest rates soon possibly as early as December. Higher rates tend to hurt stocks by making borrowing more expensive and pushing up the value of the yen, which squeezes exporters’ profits.
4. Wild Swings in Currency and Government Bonds
The yen soared against the US dollar, surging to 154.20 yen per dollar. Investors fled risky bets across global financial markets, unwinding trades and pushing up the yen. At the same time, yields on Japan’s government bonds spiked, raising the cost for businesses and putting added pressure on stock prices.
How Bad Was the Market Drop?
Here’s a look at how major benchmarks finished the session:
- The Nikkei 225 collapsed 3,643 points (down 5.96%) to end at 57,434.77. That’s the lowest closing level since April 2026 and wiped out nearly 9% for the week.
- The broader TOPIX Index slid 232.40 points (down 5.90%) to 3,707.99.
- Market breadth was extremely negative, with only 14 gainers against 207 decliners.
- The yen rocketed up to 154.20 per US dollar, a sharp move.
- 10-year Japanese government bond yields rose to 2.785% after the wage data and talk of a BOJ rate hike.
The Nikkei’s day started with a brief high just above 60,000 points. But soon after the open, selling accelerated and by late morning the index had touched a low of 56,745.81 a stunning drop of more than 7% in just a few hours.
Sectors and Stocks: Who Got Hit the Hardest?
Almost every sector was dragged lower, but technology and anything tied to semiconductors led the way down. Here’s how some big names fared:
- Ibiden Co plunged 16.3% on fresh worries that chipmakers are slashing orders.
- Advantest fell 14.7% after another tech rout in the US.
- Kioxia lost 13.1% as forecasts for memory chip demand were cut.
- Tokyo Electron slid 9.4% a huge blow to the index given its size.
- SoftBank Group, deeply invested in AI, dropped 6.8%.
- Furukawa Electric, a key supplier of fiber for data centers, fell 8.45%.
- Toyota Motor dropped 4.35% as the surging yen threatens its overseas profits.
A few utilities like Kansai Electric and Tokyo Electric Power managed to avoid the worst, falling less than 1% likely because they are more tied to domestic demand and less to volatile export markets.
Technical Breakdown: Nikkei Crashes Through Support
From a technical point of view, the Nikkei 225 broke through every key level that had previously supported it for months. By closing below the 60,000-point mark and well under the important 200-day moving average of 59,850 points the market showed clear signs of entering a true correction phase.
The 14-day Relative Strength Index (RSI), which measures how “overbought” or “oversold” a market is, tumbled from 43.5 down to 21.8. This level is considered deeply oversold, pointing to just how extreme the day’s selling was.
- Key resistance sits around 60,000 points and the 200-day moving average.
- Fresh support is unclear, with recent lows at 56,745.81 and an older floor around 55,200 from earlier in the year.
Looking Ahead: What Will Drive the Market Now?
Japan’s market enters next week facing three big questions:
1. Will the US Tech Rout Continue?
If Wall Street stabilizes, Asia might catch a break. But if US tech keeps sliding, expect more pain in Tokyo and other Asian markets.
2. How Will the Bank of Japan Act?
Investors are betting the BOJ will raise rates in December, which could further boost the yen and pressure export-heavy parts of the market. Currency swings remain a huge risk.
3. Earnings Season Brings Fresh Clues
More than 600 major Japanese companies will finish reporting mid-year results next week. Investors will watch closely for any hints about buybacks, profit warnings, or how companies plan to deal with the volatile yen.

Final Thoughts
Friday’s crash on the Tokyo Stock Exchange stands out as one of the most severe in years. The panic started with a rout in the US tech sector but quickly widened as fears over US politics, Japanese rate hikes, and currency swings piled up. For now, investors are bracing for more wild moves in both directions, as the global tech story and central bank decisions continue to shape the market’s direction. Stay ready for more volatility as the dust settles and new data comes in.
