Main Indices Unchanged as Market Takes a Break
On Monday, October 12, 2026, the Tokyo Stock Exchange stayed closed for Sports Day in Japan. Because of this pause, the key stock indexes, the Nikkei 225 and the TOPIX, didn’t move at all. They remained stuck at Friday’s final numbers: the Nikkei 225 at 69,030.92 and the TOPIX at 4,091.46.
But that doesn’t mean all trading stopped. Big investors and overseas traders kept busy through futures trading in places like Chicago, and also in the Osaka Exchange’s holiday sessions. Currency desks also stayed active, watching the yen’s continued weakness.
What’s Driving Sentiment Right Now?
Heading into the new week, two things shape trader attitudes toward Japanese stocks:
Yen Keeps Falling
The Japanese yen dropped to 158.26 per US dollar a level not seen for months. That makes life easier for major exporters, because they earn more when their overseas sales get turned back into yen.
Tech Shares Steady After Wild Friday
Tech stocks around the world bounced back a bit after a sharp dip last Friday. This helped futures on the Nikkei stay mostly steady, trading between 68,800 and 69,200.
Why Are Indices Frozen?
Trading in stocks in Japan is closed for the national holiday, so the numbers you see today are just repeats from Friday’s close.
Here’s a quick look at the main numbers:
Nikkei 225 (Cash): 69,030.92, unchanged
TOPIX Index (Cash): 4,091.46, unchanged
CME Nikkei 225 Futures: 69,120.00, up a bit
USD/JPY: 158.26, sharply weaker for the yen
10-year Japanese government bond yield: 1.165%, no change
Friday’s Rollercoaster: A Quick Recap
Friday set the tone for the current market mood. The Nikkei plunged about 900 points in the first thirty minutes, dropping to 68,150 after news broke that OpenAI’s yearly revenue was way below what analysts wanted. But buyers swept in. By the close, the index had clawed its way back almost to even, at 69,030.92. Defending the 69,000 level was a big deal and sets the stage for Tuesday’s reopening.
Money and Markets: FX and Bonds
Big Yen Weakness Helps Exporters
Major Japanese companies like Toyota, Honda, Sony, and Komatsu base their forecasts on a much stronger yen—around 140 to 142 to the dollar. With the yen now past 158, these firms should see a bump in profits since overseas sales translate into more yen.
In fact, for Japan’s top exporters, every one yen drop against the dollar can mean about 48 billion yen more in operating profit.
Bank of Japan Holds Steady
Bond trading was also on hold for the holiday, but yields on the 10-year government bond finished last week at 1.165%. Most analysts don’t expect a rate hike from the Bank of Japan until December, with a nearly zero chance of a move at the late-October meeting. Loose money policies should keep helping stocks for now.
Sectors and Stocks: Winners and Losers
Expect Tuesday’s trading to follow the trends seen on Friday.
Selling in Tech Hardware, Buying in Software
Big index names like SoftBank Group and Fast Retailing fell hard on Friday, dragging the Nikkei down as investors worried about AI spending and supply chain issues. SoftBank alone dropped nearly 4 percent.
But some tech software firms soared. Shift Inc. jumped more than 6 percent, while Nomura Research rose just over 5 percent. These firms seem shielded from hardware supply worries and are likely to keep benefitting as Japan’s companies digitize operations.
Charts: Where Does the Nikkei Go Next?
Right now, the Nikkei is trading in a tight range, just below its record high of 73,007 set earlier this year. Key numbers to watch:
- 68,617: 50-day moving average (short-term trend)
- 66,292: 200-day moving average (long-term bull line)
- 69,766: Immediate upside resistance level
For bulls, a close above 69,766 could spark a run back toward 71,000 and beyond. As long as the index stays above those moving averages, the uptrend holds.
Looking Ahead to Tuesday and the Coming Week
When the market reopens on Tuesday, traders will watch for three main signals:
- Can support above 69,000 hold, or will the Nikkei slip below 68,200?
- Are exporters set for a gap-up start, thanks to a weak yen and steady futures?
- How will profit reports for the latest quarter look, especially as exporters juggle higher costs for imported materials?
Investors will also look to Wall Street and other Asian markets for hints on Tuesday’s opening moves.
