STU48’s major debut single “Kurayami” blasts in at No. 1 on the latest Billboard Japan Hot 100 dated Jan. 29 to Feb. 4. The sixth domestic AKB48 sister group formed in March last year sold 152,003 CDs in its first week and came in at No. 1 for physical sales, No. 6 for look-ups, No. 10 for Twitter mentions, and No. 19 for radio airplay.
Physical sales and downloads were strong this week and the top 20 has shifted noticeably from last week’s chart. Ten of the top 20 songs are chart debuts, including Sumire Uesaka’s “Pop Team Epic” at No. 4. This track is the opening number of the extremely popular current anime series by the same name and has racked up points in both the physical metrics (No. 13 for sales, No. 7 for look-ups) and the digital (No. 2 for downloads, No. 12 for Twitter), coming out on top over this week’s most-downloaded song, EXILE’s “Party All Night: Star of Wish” that bowed at No. 6 on the Japan Hot 100.
The video views metric of the Japan Hot 100 combines total streams from YouTube and GYAO!. TWICE’s “Candy Pop” rises to No. 1 this week after maintaining the No. 2 spot for three consecutive weeks, finally coming out on top over Yoko Oginome’s long-leading “Dancing Hero.” Twitter mentions for “Candy Pop” is on the rise as well (No. 3), and combined with the points for physical sales and look-ups next week, the song is expected to climb further up the Japan Hot 100.
