Last year, Justin Bieber retweeted a video of the brainwashed song "Pen-Pineapple-Apple-Pen" sung by Japanese YouTube celebrity Piko Taro on twitter. Recently, Justin Bieber worked with the music geek to shoot an advertising film for the Japanese Software Bank. It is a Mobile phone and telecommunications company headquartered in Tokyo.
Dressed in a traditional blue Japanese costume, Justin Bieber tried to practice saying "hello" in Japanese, and then he took a selfie and went to a school.
He walked through a corridor, followed by many students from the school. He poked his head into a classroom where PIKO Taro was lecturing. After they greeted each other, the two gave lessons to the students together, and Justin also clapped his hands with the students afterwards.

Justin and Pico Taro have been related before. In August last year, PICK Taro released a brainwashing song "Pen-Pineapple-Apple-Pen", and Justin Bieber, who had 90 million followers on Twitter, thought the song was very interesting and retweeted the song on his twitter.
The ad they worked on gave them a chance to meet each other in person. The plot of the two using pineapples and apples to teach students in the classroom is a metaphor for this song by Piko Taro. And on the chalkboard behind them were the lyrics of the song.
The purpose of the ad they shot was to promote the Software Bank Group's discount campaign for students between the ages of 18 and 25. For the full video of the ad, please stamp:
Just recently, Justin Bieber was filmed for a T-Mobile Super Bowl commercial. In the commercial, he wore a tuxedo and told people about the history of the celebration of the success of rugby touchdowns. Speaking of "high-five celebration," the singer turned behind him. In the scene behind him, professional footballer and New England Patriots' midfielder Rob Gronkowski, dressed as an ancient caveman, is celebrating with the people next to him.
