J-pop boy band JO1 (pronounced "jay-oh-one") shoots to No. 1 on the latest Billboard Japan Hot 100 (dated March 2 to 8) with its debut single, "INFINITY." The new 11-member group, formed through the audition program PRODUCE 101 JAPAN, led physical sales with 344,299 copies sold and also topped Twitter mentions, where they have charted for seven weeks.

The metric for look-ups, which counts the number of times a CD is ripped to a computer, usually coincides with physical sales, but this week's No.

1 goes to Mr. Children's new single, "Birthday," which debuts at No. 3 on the Japan Hot 100. The veteran pop band's first new single in almost three years sold 64,698 copies and comes in at No.
