The Japanese women's team won the inaugural Pan Continental Curling Championships on Sunday, beating South Korea 8-6 in the final following an additional 11th end.
Represented by the Kitami, Hokkaido-based Loco Solare outfit that won silver at February's Beijing Winter Games, Japan had already secured its spot at next year's women's world championships by finishing among the top five teams in Calgary.
Japan led 6-3 after taking a point in three straight ends from the sixth. It let South Korea back into the match by conceding a point in the ninth and two in the 10th before prevailing in the extra end.
Japan's men claimed one of the four world championship qualifying spots up for grabs at the tournament, bouncing back to finish fourth on Saturday after opening with four straight losses.
