The Nikkei fell 0.85% at 44,550.85, its lowest close since September 11. The index lost for a fourth straight session.
The broader Topix lost 1.37% at 3,094.74.
“It is a retreat from the rally that boosted the Nikkei until last month,” said Shuutarou Yasuda, a market analyst at Tokai Tokyo Intelligence Laboratory.
“Investors wanted to take profits, so sold the stocks that rose the most, such as Tokyo Electron and SoftBank Group.”
Chip-making equipment maker Tokyo Electron surged 27.6% in September in its largest monthly gain since February 2024, making it a key driver behind the Nikkei’s record high hit last month. The index added 5.2% in September in its sixth straight month of gains. On the day, Tokyo Electron fell 2.09% and technology start-up investor SoftBank Group lost 2.38%, becoming the biggest drags on the Nikkei. Chip-testing equipment maker Advantest edged up 0.17%, tracking overnight gains in the U.S. chip index.
All but two of the Tokyo Stock Exchange’s 33 industry sub-indexes fell.
The bank index slipped 3.07% to become the worst-performing sector. Mitsubishi UFJ Financial Group and Mizuho Financial Group lost 3.17% and 3.83%, respectively.
The real estate firm index fell 2.83%
Drug makers rose 0.95%, with Otsuka Holdings and Chugai Pharmaceutical up 5.22% and 3.86%, respectively.
