Kiwi sailing crews have kicked off the 2018 World Cup regatta in Japan with a bang, taking four top-10 berths on the first day.
New Zealand dominated the 49er fleet in proceedings cut short by poor conditions, winning the day's sole race through Isaac McHardie and William McKenzie.
The pair finished seven seconds clear of second place, while fellow Kiwis Logan Dunning Beck and Oscar Gunn finished sixth.
Josh Porebski and Trent Rippey came in 10th.
"It was a game of snakes and ladders - you could gain just as easily as you could lose, (so) you had to bank what you could," McHardie said.
