The Japanese male vocal and dance group Sandaime J Soul Brothers from EXILE TRIBE released its first single in a year and a half after members spent the better part of last year working on solo projects. "Yes we are" bows at No. 2 on the Japan Hot 100, racking up points in a balanced way: No. 2 for physical sales with 63,732 copies sold, No. 2 for Twitter, No. 3 for downloads, No. 5 for streaming and look-ups, No. 9 for video views, and No. 10 for radio.
Rock band BUMP OF CHICKEN debuts at No. 5 with "Aurora," the theme song of the TBS drama The Good Wife, a Japanese remake of the Emmy-winning American TV series executive produced by Ridley Scott. The popular pop-rockers ruled downloads this week and broke into the top 5 fueled by this metric.
back number's "HAPPY BIRTHDAY" slips a notch to No. 6 on the Japan Hot 100 but is still going strong, dethroning Keyakizaka46's "Kuroi Hitsuji" in look-ups and coming in at No. 2 for downloads this week.
The Billboard Japan Hot 100 combines physical and digital sales, radio airplay, Twitter mentions, YouTube and GYAO! video views, Gracenote look-ups and audio streams from Amazon Music Unlimited, Apple Music, AWA, Google Play Music, KKBOX, LINE MUSIC, Rakuten Music, RecMusic provided by Gfk Japan, streaming counts based on lyrics displayed on PetitLyrics, and karaoke data from Daiichikosho and XING.
