Hey! Say! JUMP’s “Your Song” bows at No. 1 on Billboard Japan Hot 100, dated Sept. 28 to Oct. 4, selling 215,442 copies in its first week. The theme of the ongoing TV drama series K2 starring member Ryosuke Yamada led physical sales, look-ups, and Twitter mentions this week while also coming in at No. 2 for radio airplay to take the top spot on this week’s tally.
YOASOBI’s “Yoru ni kakeru” and BTS’ “Dynamite” continue their close competition, with the K-pop group racking up 10,106,414 streams to hold at No. 1 for the metric as the J-pop duo logs its 18th week at No. 1 for video with 6,423,249 views this week.
Meanwhile, Japanese band BUMP OF CHICKEN debuts at No. 4 on the Japan Hot 100 with “Acacia” — featured in the animated “Pokémon Special Music Video” GOTCHA! — leading downloads with 62,255 units sold. While the track can’t be counted towards the Billboard Japan Hot Animation chart as it’s not a theme song per se, the collaboration between the veteran pop-rock band and the Pokémon series proved to be a strong combo, out-selling the highly anticipated “Whenever You Call” by Arashi in first-week digital sales (the Bruno Mars-produced single sold 58,989 units).
The Billboard Japan Hot 100 combines physical and digital sales, radio airplay, Twitter mentions, YouTube and GYAO! video views, Gracenote look-ups, audio streams from Amazon Music Unlimited, Apple Music, AWA, Google Play Music, KKBOX, LINE MUSIC, Rakuten Music, RecMusic provided by Gfk Japan, dHits, Uta Pass and Spotify, plus karaoke data from Daiichikosho and XING.
