<a href="/music/Keyakizaka46">Keyakizaka46</a>'s "Garasu Wo Ware!" rules this week's Billboard Japan Hot 100 chart dated March 5 to 11, jumping 18-1 with 893,632 CDs sold in its first week. The J-pop girl group's new single is off to a better start sales-wise compared to its previous No. 1 song "Kaze Ni Fukaretemo" that started off its first week with 722,954 copies sold.

The song excelled in all metrics of the chart's measurement this week, coming in at No. 1 for physical sales, look-ups and Twitter mentions, No. 2 for downloads, No. 3 for streaming and video views, and No. 17 for radio airplay. This result reflects the group's growing popularity outside of its devoted fan base, and the single finishes first by a considerable margin.

After holding steady at No. 2 for three consecutive weeks, <a href="/music/Kenshi-Yonezu">Kenshi Yonezu</a>'s "Lemon" slips to No. 3 on the Japan Hot 100. But it looks like the track is set to stick around in the upper ranks of the chart as it still rules downloads for the fourth consecutive week and also sits at No. 1 for video views for the second week in a row (over 8.9 million views).

Last week's No. 1 song, "Doraemon" by <a href="/music/Gen-Hoshino">Gen Hoshino</a>, drops to No. 4 on the Japan Hot 100 but is the most-streamed song this week and is still showing strong performance in other metrics as well.

March is graduation season in Japan, and <a href="/music/Remioromen">Remioromen</a>'s "Sangatsu Kokonoka" (meaning "March 9th"), a song released in 2004 and now a popular favorite at graduation-related get-togethers, climbs the Japan Hot 100 every year around this time. It's back in the top 10 this week and enjoying its annual resurgence, gaining points through Twitter mentions (No. 5), streaming (No. 7), downloads (No. 12) and radio airplay (No. 13).

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 Apple Music, AWA, Google Play Music, KKBOK, LINE MUSIC, Rakuten Music, Recochoku provided by Gfk Japan, as well as streaming counts based on lyrics displayed on PetitLyrics.
