Nikkei 225 closes up 0.8% at 65,513.99; Topix slips 0.4%

The divergence between the Nikkei 225 and Topix points to a narrow, blue-chip-led advance rather than broad market strength, since the wider index actually softened. That kind of split often signals concentration in a handful of large names rather than improving sentiment across the market. Whether the two benchmarks continue to decouple, or the Topix catches up, is the open question worth watching.
