Nikkei 225 closes down 1.7% at 65,269.33

The Nikkei's slide signals a broad risk-off session in Japanese equities, but the move's significance depends on whether it stems from domestic fundamentals or external spillover. For market watchers, the key is whether this is a one-off correction or the start of sustained pressure on the Topix, which fell slightly more, hinting at weakness across mid- and small-caps. The absence of a stated catalyst in the report leaves the driver unclear, making the next session's breadth and volume the tell for whether sellers retain control. This matters to anyone tracking Asian equity flows, as Japan often leads regional sentiment.
