Nogizaka46's 25th single, "Shiawase no hogoshoku," shoots to No. 1 on the latest Billboard Japan Hot 100, dated March 23 to 29, selling over a million copies in its first week following last week's chart-topper by AKB48.

The J-pop girl group's newest release, the last one featuring departing member Mai Shiraishi, sold 1,049,667 copies, leading physical sales and look-ups. The song also performed relatively well in the digital metrics of the chart's methodology: No. 2 for Twitter mentions, No. 6 for radio airplay, No. 12 for downloads, and No. 61 for streaming.

In terms of sales figures, the group's previous single, "Yoake made tsuyogara nakutemo ii," sold 1,019,039 copies, while the one before that, "Sing Out!," sold 1,058,575 copies, so no major differences there.

Official HIGE DANdism's "I LOVE…" holds at No. 2 for the fifth non-consecutive week. While the band continues to chart four songs in the top 10, the points for each are decreasing somewhat: "I LOVE…" falls in every metric except karaoke, and "Pretender" falls in all but radio and Twitter.

King Gnu's long-running hit "Hakujitsu" is also beginning to slow down in its two strengths -- streaming and video views -- and it's looking like the tide regarding the top 10 mainstays is starting to turn.

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.
