Kean, alongside partner Jo Butterfield, delivered a dominant 11-2 drubbing of Japanese pair Yoji Nakajima and Aki Ogawa who claimed gold in the World Championships in Scotland just last year.
It marked their third consecutive win in the round robin, having overcome defeats in their opening two matches, and leaves them second in the standings.
“I’m over the moon with that one. We dominated the first five ends. It was fantastic,” enthused Kean.
“There’s no real secret sauce to it. It’s what we’re trained to do. You’re going to make some mistakes out there, you would have seen that in some of the ends and it’s trying to reset and then trying to get going again.
“We know we’re capable of making some brilliant shots. And so long as you’re getting something from every stone and putting your opponents under pressure to do something, generally you get a good result.
Freshly-dubbed Team JJ came out firing from the off, giving Japan almost nothing to work with in the first half.
They dominated the opening five ends to accrue an 8-0 lead heading into the sixth end with the game already all but won.
While the sixth end saw them concede two stones, it was a slight they clearly took offence to, as Butterfield delivered a brilliant shot to clear the house of two red stones and earn a 3-0 win in the seventh end.
And having lost their opening two matches, wins against the USA and Latvia have set up a remarkable turnaround by the duo.
“We’re so happy,” said Butterfield. “We played really well. We’ve grown into the competition. We’ve played better in every game we’ve played and that was a demonstration out there.
“We had control of every end, and we didn’t give them an inch. That’s how we want to try and continue.”
They will face table-toppers China on Sunday and will hope to dent the momentum of the pair who boast a 100% record in the round robin so far.
