Pro-democracy chants in Hong Kong as fireworks cancelled
Pro-democracy protesters and revellers flocked to sites across Hong Kong to usher in 2020, but the semi-autonomous Chinese city had toned down its New Year's celebrations amid the months-long demonstrations.
A fireworks display that traditionally lights up Victoria Harbor was cancelled amid safety concerns. Despite this, thousands welcomed 2020 on its neon-lit promenades and many broke into pro-democracy chants shortly after the countdown to midnight.
Instead of fireworks, a "Symphony of Lights" took place, involving projections on the city's tallest skyscrapers, while smaller-scale pyrotechnics were launched from waterfront rooftops.
Australia sees in the new roaring 20s
Australia ushered in the New Year with a huge fireworks display in Sydney, despite the calls to cancel the event as devastating bushfires raged across the country.
A petition to cancel the event out of respect for fire victims attracted more than 280,000 signatures. Fireworks displays were scrapped in Australia's capital, Canberra, and Sydney's western suburbs due to elevated fire danger and extreme weather conditions.
Critics had wanted Sydney to use the Aus $6.5 million ($4.5 million) spent on the display to fight bushfires ringing the city, but officials said the event was worth Aus $130 million to the economy and cancelling it would not have helped those impacted by the fires.
More than 100,000 fireworks lit up the skyline for the hundreds of thousands of spectators thronging the city centre.
Crowds were warned to take care as strong winds gusted in the harbour, forcing the cancellation of a boat display that would have blasted water into the sky.
Japan's new era celebrates its first New Year's
People flocked to temples and shrines in Japan, offering incense with their prayers to celebrate the passing of a year and the first New Year's Eve of the Reiwa era.
Under Japan's old-style calendar, linked to emperors' rules, Reiwa started in May, after Emperor Akihito stepped down and his son Naruhito became emperor. Although Reiwa is entering its second year with 2020, Jan 1 still marks Reiwa's first New Year's, the most important holiday in Japan.
The first year of the new decade will see Tokyo host the 2020 Olympics, an event that is creating much anticipation for the capital and the entire nation.
It's officially 2020 now in New Zealand
As the most populated city in New Zealand, Auckland always puts on a good show and the Sky Tower display was spectacular as half a ton of fireworks burst from the landmark towering over the city centre.
Thousands gathered around the tower, where - for the first time - lasers and animations accompanied the fireworks display.
The countdown is now on to Australia. Sydney and Brisbane have already staged smaller displays for families that drew gasps.
More than a million people have descended on a hazy Sydney Harbour and surrounding areas ahead of the ringing in of the New Year, despite the ongoing wildfire crisis ravaging New South Wales, Australia's most populous state.
Brisbane's family display
The planned 9pm fireworks for families over Sydney's landmarks was delayed by 15 minutes due to strong winds.
Some communities have cancelled New Year's fireworks celebrations, but Sydney Harbour's popular display was granted an exemption to a total fireworks ban that is in place there and elsewhere to prevent new wildfires.
South Korea and Samoa have started the party
Thousands of South Koreans filled the downtown streets in Seoul ahead of a traditional bell-tolling ceremony near City Hall. Dignitaries picked to ring the old Bosingak bell at midnight included South Korean Major League Baseball pitcher Hyun-Jin Ryu and Pengsoo, a giant penguin character with a gruff voice and blunt personality that emerged as one of the country's biggest TV stars in 2019.
South Korea welcomes the new decade
In Samoa, fireworks erupted at midnight from Mount Vaea, overlooking the capital, Apia. The Pacific island nation of Kiribati was also one of the first countries to welcome the new decade. The nation's 3,200 coral atolls are strewn more than 3 million square miles, straddling the equator.
