Saitama Wild Knights overpowered Super Rugby's Chiefs 38-14 in the second Cross-Border Rugby match between teams from Japan and New Zealand on Sunday.

The Robbie Deans-coached Wild Knights flew the flag for Japan Rugby League One a day after Tokyo Sungoliath fell 43-7 to the Blues in the series opener.

The match at Kumagaya Rugby Stadium served as a preseason warmup for the Hamilton-based Chiefs, while the title-contending Wild Knights are six games into a League One campaign in which they remain undefeated.

It also saw Saitama's former Chiefs flanker Lachlan Boshier line up against his old team in a battle of No. 7s with younger brother Kaylum, who captained the visitors.

Wild Knights lock Lood de Jager was denied an early five-pointer when he was held up in goal, but the hosts soon had their opening try as Atsushi Sakate dotted down from a well-executed lineout.

Scrumhalf Taiki Koyama scored a converted try to put the Wild Knights up 14-0 midway through the first half, pouncing as the ball emerged from a Chiefs ruck on their own try line.

The visitors did not get on the board until Josh Ioane touched down and kicked the extras for a 17-7 deficit in the 52nd minute.

Saitama added further tries through Marika Koroibete, Mark Abbott and replacement back Kyohei Yamasawa, who ran in from an intercept and then kicked the final points after the siren.

Wild Knights flanker Boshier said he had relished the opportunity to face his old team, starting from their ceremonial pre-game haka war dance.

"I didn't think that I'd face the Chiefs haka after being involved with the Chiefs, but it's awesome to see at the start of the game," the 29-year-old Boshier said.

"It was good to have a tough game today. We've got a few more tough games coming up, so it was good to get the bodies ready."

Younger brother Lachlan said it had been a "good, hard battle" playing against his older sibling for the first time.

"Hats off to Panasonic today," said the 24-year-old, referring to the Japanese club's corporate name. "They've been the top team in League One for many years, and today they showed why."

The Chiefs face Kubota Spears and the Blues will play Yokohama Eagles next Saturday in the final two Cross-Border Rugby matches.
