Nikkei 225 closes up 1.4% at 65,018.95; Kospi gains 2.7%

The divergence within Japan — the Nikkei up sharply while the broader Topix slipped — points to gains concentrated in index-heavy names rather than a broad risk-on move, which matters for anyone reading the headline as a regional rally. Korea's stronger advance suggests the session's momentum was not Japan-specific. Whether that split between Japanese benchmarks persists is the open question.
