YOASOBI’s “Yoru ni kakeru” takes the top spot on the latest Billboard Japan Hot 100, marking the first No. 1 for the rising duo. The group with roots in the J-pop internet scene quickly rose through the ranks since its debut on the tally 10 weeks ago, and coverage on terrestrial TV programs during the chart week provided the extra boost it needed to reach No. 1.
“Yoru ni kakeru” led streaming and video views for the week dated May 18 to 24, with the latter almost doubling to 13,890,300 views from 7,133,036 the week before. This is a feat in itself, as the figure comes in third place after viral sensation Pikotaro’s “PPAP” (26,777,714 views) and superstar Gen Hoshino’s “Koi” (17,018,090 views) in terms of a song’s highest weekly video views since the chart began including the metric back in June 2015.
YOASOBI’s new song “Harujion” also holds at No. 10, where it debuted last week.
Last week’s No. 1, Eito’s “Kousui,” falls to No. 3 but is still going strong in terms of total points, with downloads increasing to 9,870 units from 8,652 last week and streaming to 6,172,039 streams from 5,755,840. But LiSA’s “Gurenge,” the theme song of the hugely popular anime series Demon Slayer: Kimetsu no Yaiba, added points in all metrics including physical sales this week due to the original manga the anime is based on ending its serialization in the Weekly Shonen Jump magazine.
“Kousui” was first popularized on TikTok, and many users have been posting their own covers of the song on the platform, suggesting that this number will become a karaoke favorite once the rooms reopen after closing down during the coronavirus state of emergency, which was lifted on Monday (May 25). While the track is still not included on karaoke streams due to businesses scaling back operations during the hiatus, “Kousui” will most likely rise again when the Japan Hot 100 reintroduces the metric in its calculations once the data becomes available again.
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 (excluded until further notice).
