Nikkei 225 and Topix Both Rise 3.4% by Morning Close

The symmetry is the story: both benchmarks posting an identical 3.4% gain points to a broad, index-wide bid rather than a narrow, sector-driven move — a distinction that matters for judging whether the rally reflects genuine breadth or a single heavyweight pulling the tape. With no sector or driver detail in the update, the catalyst remains unverified, and that gap is itself notable for anyone tracking Japanese equities as a risk-appetite proxy. Whether the two indices continue moving in lockstep through the full session, or diverge as sector specifics emerge, is the open question.
