South Korea’s KOSPI Closes Up 0.87% as Japanese Markets Stay Shut

With Tokyo shut, Seoul traded without its usual regional anchor, which makes the session's move harder to attribute to any single driver. The read-through is mostly about liquidity and price discovery: a single-market session can amplify moves that might otherwise be absorbed by cross-market flows, so the 0.87% gain says more about thin regional participation than about a durable shift in sentiment. Whether Seoul's next session converges with or diverges from Tokyo once Japanese trading resumes is the open question.
