Asian shares mixed as omicron worries crimp market optimism

Asian shares are rising although optimism set off by a rally on Wall Street was dampened by concerns about the potential impact of the omicron coronavirus variant

TOKYO -- Asian shares rose Tuesday, although optimism set off by a rally on Wall Street was dampened by concerns over the potential impact of the omicron variant of the coronavirus.

Japan's benchmark Nikkei 225 jumped 1.4% to finish at 29,069.16. South Korea's Kospi gained 0.5% to 3,015.63. Hong Kong's Hang Seng recouped early losses to edge up 0.2% to 23,269.36, while the Shanghai Composite gained 0.4% to 3,628.77. Trading was closed in Australia for Boxing Day.

Much of Asia has yet to see surges in infections of the omicron variant already playing out in other parts of the world, but experts are warning the region likely won't be spared.

In Japan, which hasn't had such a wave of new cases so far, many areas are bustling with yearend shoppers, and events are being held with spectators, although most people are wearing masks.
