PNG stumbled across the line against invitational side Cricket Without Borders and Samoa comprehensively defeated Vanuatu.
The Cook Islands won the toss and put Japan in to bat.
It was another methodical top order display from Japan, who looked in charge at the crease against the Cook bowlers.
Japan were hitting the ball hard, playing some forceful shots down the ground, and rotating the strike easily.
Back in the side after two years away from the game, opener Ema Kuribayashi looked dominant scoring 25 runs before she hit the ball in the air, getting caught at mid-off off the bowling of Lacynthia Rani.
Despite Japan’s sound beginning, the Cook Islands team kept their energy in the field, putting pressure on the Japanese batswomen.
The Cook Islands fielders were rewarded for their efforts with three run outs, a catch and a stumping by the halfway point of the match, leaving Japan 73-5 after 12 overs.
However, there was some ill-discipline in the field from the Cook Islands in the final eight overs of the match and Japan capitalised.
The hosts accelerated the run rate to over seven runs per over in the last five overs to finish with a score of 148 runs.
It was a slow start to the Cook Islands’ batting innings, scoring at less than two runs per over.
The Cooks showed some resistance shortly after the power play overs and pushed the run rate up to just under four runs per over.
But losing regular wickets meant they couldn’t maintain it, and by the half-way point the Cook Islands were in real trouble at 37-3.
Unfortunately it didn’t get any better for the Cook Islands’ batswomen as the required run rate grew with each passing over.
With just six overs to go they needed an out of reach score of 93 runs to win.
In the end it was a mechanical win for team Japan.
Although a disappointing loss for the Cook Islands team, there were some highlights.
Lacynthia Rani bowled an economical spell conceding just 13 runs and picking up two wickets in her four overs.
While Cook Islands number four Punanga Kaveao top scored in the match with 43 not out.
The Cook Islands now look ahead to face invitational team Cricket Without Borders.
