Nikkei 225 Opens 0.6% Higher; Korean Markets Closed for Holiday

With Seoul closed, Tokyo is carrying the region's price discovery alone, so the Nikkei's move reflects a thinner, less cross-checked read on Asian risk appetite than a normal session would. That matters most for regional allocators who use Korea and Japan as a paired signal and now have only half the picture. Whether the gain holds without Korean participation is the open question, and the next session that brings Seoul back online is where the two markets' views get reconciled.
