Papua New Guinea and Japan are the only unbeaten teams after the first day of the East Asia-Pacific Women's Cricket Trophy in Sano, Japan.
Runners-up in the previous two tournaments, the PNG Lewas proved too strong for both Vanuatu and the Cook Islands.
Pauke Siaka led the way, top-scoring with 24 and 42 in both games while also grabbing 2-13 with the ball against the Cook Islands.
Hosts Japan were pushed before beating invitational side Cricket Without Borders by 26 runs in an early morning friendly game.
Then in the afternoon the defending champions left it until the last ball to overhaul Samoa's 106-7.
Despite her side ending on a losing note, Samoa captain Regina Lili'i led from the front with 45 runs vs Japan and five wickets across both games.
"Very good - I mean everyone was really energised, really excited so everyone was on their toes [and] there's lots of chatter out there. There were a few girls that were doing their debut so they were really excited."
Meanwhile Vanuatu managed a win against Cricket Without Borders in the afternoon.
