Nikkei 225 slips 0.1% at Tokyo morning close, Topix gains 0.5%

The divergence between the two Tokyo gauges is the story: the blue-chip Nikkei slipping while the broader Topix advances points to weakness concentrated in heavyweight names rather than across the market. That distinction matters for anyone reading Japanese equity moves as a single signal, since index-level headlines can mask where the actual selling sits. Whether the split persists into the afternoon session is the open question.
