China were runners-up in both competitions with home skip Eunjung Kim leading the South Koreans to a 5-3 victory in today's final.

The pivotal end for the hosts - whose line-up also included second Seonyeong Kim, third Kyeong-Ae Kim, lead Yeongmi Kim and alternate Chohi Kim - came in the eighth when the skip played her two final stones to perfection.

She first cleared out Chinese stones lying in the house before removing a scoring stone with her last effort and claiming two points for her country in the process.

That put South Korea 5-3 up and they did not relinquish their advantage.

"The Chinese skip [Bingyu Wang] as you know is very good," said Eunjung Kim, who can now look forward to a home Winter Olympics in Pyeongchang in 2018.

"We thought that the game worked out well because we didn’t make any mistakes and we did one point each."

All four finalists today have also qualified for next year's World Championships, due to take place in Beijing from March 18 until 26. 

"We have been waiting for this opportunity for a long time especially because we have the Pyeongchang Olympics in 2018 so we want to show our best performance in the World Championships in the coming session," Kim added.

In the men's final Japan, led by skip Yusuke Morozumi and featuring third Tetsuro Shimizu, second Tsuyoshi Yamaguchi, lead Kosuke Morozumi and alternate Kohsuke Hirata, beat China by the same score as the women's final, 5-3.

A double takeout from Morozumi in the penultimate ninth end split the house and left the Japanese in scoring position when 3-2 up.

China then erred as they pushed their own stone out of the rings, allowing Japan to steal two and open up a 5-2 advantage.

The Chinese pulled a point back but had to settle for the silver medal, as Japan banished memories of coming second at the four previous editions of the tournament. 

"Yesterday, we made it to the Worlds and now we’ve won," said Morozumi. 

"I’m feeling super happy. 

"We couldn’t win over China in the final, we’ve never defeated them, but now we’ve won and we’re Pacific-Asia champions, this means a lot for our confidence and energy."

In bronze medal clashes, South Korea's men beat Chinese Taipei 8-6 on home ice.

Japan's women beat New Zealand 5-3.
