The 12-5 victory means the Japanese team - made up of skip Seina Nakajima, fourth Ikue Kitazawa, third Chiaki Matsumura and lead Hasumi Ishigooka - have qualified their country for the 2020 World Women's Curling Championship in Canadian city Prince George.

In the first end of the game, Kitazawa drew for three points to establish an early 3-0 lead for her side at the Shenzhen Universiade Sports Center.

Two points in each of the next two ends saw Hong Kong fight back and go 4-3 ahead, but Kitazawa threw the perfect weight and line for a precise tap back in the fourth to score three points and earn Japan a 6-4 advantage. 

After that, Japan stole three ends in a row before Hong Kong hit for one point in the eighth and ended the game in their opponent's favour.

"We're very happy to have a place in the Worlds," Nakajima said.

"That's a big thing for us, but our goal here is to win the gold medal, so we'll do our best in the final."

Earlier in the day, Hong Kong had become the final team to qualify for the women's semi-finals, following a 10-4 win over Qatar.

Already qualified China, Japan and South Korea all won their final round-robin games to move onto identical records of six wins and one loss, meaning their final ranking had to be determined by the draw shot challenge.

Hosts China beat Australia 11-2, Japan defeated Kazakhstan 11-0 and South Korea overcame Chinese Taipei 14-2. 

Japan finished top of the standings to set up their meeting with fourth-placed Hong Kong, while South Korea came second and China ranked third.

The second semi-final, between South Korea and China, is scheduled for tomorrow.

The gold medal game is set for Saturday (November 9).

In the men's event, the teams were already set for tomorrow's semi-finals with South Korea, Japan, China and New Zealand the top four in the 10-strong field.

The ninth and final session determined ranking positions, and who will face off in the last four.

South Korea checked off their ninth victory and finished the round-robin as the only unbeaten side after defeating China 11-1.

In the first end, South Korea's skip Kim Chang-Min made a nose hit for two points to open the game. 

Then, in the second end, China’s skip Zou Qiang faced three counter stones on his draw for one point. 

His stone slid too far, giving South Korea a steal of three points and a 5-0 lead. 

China did not recover from the early deficit and South Korea ultimately triumphed by a comfortable 10-point margin.

Awaiting South Korea in tomorrow's semi-finals are fourth-placed New Zealand, who picked up their sixth win today with an 11-4 success over Kazakhstan.

The other semi-final pits third-placed China against runners-up Japan, 13-2 victors at the expense of Hong Kong.

Today's two other matches saw Australia and Chinese Taipei finish on a winning note.

Australia beat winless debutants Nigeria 19-1 and Chinese Taipei defeated Qatar 10-2.
