Nikkei 225 Falls 2% Intraday; Topix Down 2.2%

With no specific catalyst cited, the selloff looks sentiment- or flow-driven rather than tied to a discrete event, which makes the breadth of the move — both benchmarks falling in tandem — the more telling detail. Japanese equities sit at the intersection of global risk appetite and domestic policy expectations, so a same-day drop of this size without an identifiable trigger leaves the cause unresolved. Whether the decline is contained to a single session or extends into a broader repricing is the open question.
