Tokyo led a rally in Asian shares Wednesday, tracking overnight gains on Wall Street that saw the Nasdaq close at a fresh record.

In South Korea, where Samsung Electronics logged a record profit of $10.0 billion for the third quarter and announced a sweeping reshuffle of its top management on Tuesday, the Kospi index rose 1.0 percent, despite data showing October exports rising by less than expected.
