SB19 performs 'Lawless' in Japanese television show 'DayDay.'

SB19 charmed Japanese audiences with their guest appearance on morning show "DayDay." on Thursday.

The P-pop Kings performed their latest single "Lawless" and played the popular hammer game with the hosts.

The program also prepared an introduction video showing SB19's achievements, including their historic Lollapalooza set. After seeing the watch parties nationwide, one of the hosts compared them to Manny Pacquiao.

"Thank you so much DayDay. for having us here today. It's such a wonderful experience for us," Justin said.

"For our fans thank you so much for always supporting us wherever we are and here in Japan right now we will do our best and we'll always make sure that you'll be proud of us," he added.

"DayDay." is an information and entertainment talk show that airs weekdays at Nippon Television.

On Instagram, SB19 shared behind-the-scenes photos of their first-ever appearance on Japanese television.

"Who would have thought? We were once just dreamers with big dreams, and now we can check another one off our bucket list: being featured on national TV in Japan," the caption read.

SB19 will perform at the Summer Sonic this weekend. On Friday, they will hit the Massive Stage in Osaka and then head to Tokyo on Saturday for their set at the Pacific Stage.

After the festival, the group will hold their I WaS There Thanksgiving Fan Meet in Yokohama on August 18.

Fans who wish to buy their merchandise can head to the Wakas at Simula: The Pop-Up Store at the Tower Records Shibuya Store from August 10 all through 18. An SB19-themed vending machine will be also set up at the Yokohama Station on August 17 and 18.
