Japan’s Nikkei 225 climbed 850.21 yen, or 1.30%, to 66,364.20 on Wednesday, extending its advance to a fifth straight session as heavyweight AI and semiconductor shares kept drawing bids and bank stocks gained on rising long-term yields.
Nikkei 225 Rises Above 66,000 on AI and Banks

The move pushed the index back above 66,000 for the first time since Oct. 7 and underlined how a narrow group of large-cap tech names can still set the tone for Tokyo trading. More than 70% of Prime Market shares rose, showing the rally broadened beyond the marquee growth names that have dominated the index’s climb.
The Topix rose 53.29 points, or 1.31%, to 4,128.59, reinforcing the strength of the broader market. The combination of higher bond yields and a stronger earnings backdrop for lenders helped financials participate alongside AI and chip stocks, a mix that supports the market even when technology leadership looks extended.
From a technical standpoint, the Nikkei has moved back above its 50-day moving average and remains well above its 200-day average, while the Relative Strength Index has climbed toward overbought territory after the latest run. That suggests momentum is strong, but the market may need fresh catalysts to sustain the pace of gains.
For investors, the rally keeps Japan in focus as a market where semiconductor exposure, bank profitability and yen moves can all drive index performance at once. The next test is whether the advance can hold if AI leaders pause, or whether follow-through buying in financials and other cyclicals can keep the Nikkei anchored above the 66,000 level.
