Nikkei 225 closed at 64,243.30 on 2026-09-03, slumped 3.0% on the session and is +27.6% year-to-date. Here is what the market data shows.

Japan's Nikkei 225 closed lower on Wednesday, slipping 2.98% to finish at 64243.3 and extending a soft patch that has left it down 2.45% over the past week and 3.73% over three months. Even after the slide it remains 27.62% higher for the year to date.

The selloff put the index back below its 50-day moving average of 66946.15, though it held above the 200-day line at 58762.81. At the close it sat 11.22% under its 52-week high of 72366.34 and 53.18% above its 52-week low of 41938.89.

The move tracked a weak session across much of Asia rather than a single domestic catalyst. Neighbouring Korea's KOSPI fell 3.04% and Australia's ASX 200 dropped 0.92%, while Hong Kong's Hang Seng eased 0.93%. Because world markets close at different hours, the peer readings are not all from the same session: US benchmarks including the S&P 500, Nasdaq and Dow posted gains of 0.46%, 0.45% and 0.56% respectively, but those closes are dated September 2, a day ahead of Tokyo's, while Europe's FTSE 100, DAX and CAC 40 were little changed to lower on September 1.

A report from Livemint tied the regional weakness to fresh concerns around a US-Iran conflict, noting the Nikkei and Kospi fell as much as 3%. A separate tradingkey.com headline pointed to losses in Samsung, SK Hynix and Kioxia weighing on the two markets.

The data does not establish a single confirmed driver for the move beyond the geopolitical unease flagged in those headlines; the index's own corporate news flow was thin. What is clear is that a risk-off turn in Asia, not a Japan-specific development, drove the session.
