Nikkei 225 closes down 0.6% at 64,916.70

The split between a lower Nikkei and a marginally higher Topix points to weakness concentrated in the large-cap names that dominate the index rather than broad-based selling, so the headline number overstates the mood. The far stronger Kospi suggests regional money is rotating toward Korean equities rather than exiting Asia outright. Whether that divergence persists into the next session, or the Topix's resilience gives way, is the open question.
