Hakata-based girl group HKT48’s "Kiss Ha Matsu Shika Nainodeshouka?" blasts in at No. 1 on the latest Billboard Japan Hot 100 chart dated July 31 to Aug. 6, after selling 284,698 copies in its first week and coming in at No. 1 for physical sales, No. 7 for look-ups, No. 10 for Twitter mentions, and No. 70 for downloads.

Following at No. 2 this week is BOYS AND MEN, another regional group based in the Tokai region of Japan.

Mr. Children’s "himawari" and "Hanabi" come in respectively at No. 2 and No. 3 in downloads. "Hanabi" is a song from 2008 and was boosted by the hit of the band’s latest single, but is currently ranking higher than the new song in the video viewing metric, which is a rare chart phenomenon.
