Lady Gaga's new single with Ariana Grande, "Rain on Me," blasts into the top 10 from No. 68, fueled by radio airplay (No. 1) and streaming (debuting in the top 100 at No. 16). While Western pop songs rarely make it into the upper ranks of the Japan Hot 100, the talked-about collaboration by the two superstars follows Billie Eilish's "bad guy" that last charted in the top 10 in March.
A song that hit No. 3 on TikTok's weekly ranking last week called "Haru wo tsugeru" by yama has also entered the top 10 this week at No. 7. yama is a singer-songwriter who got started uploading cover videos online about two years ago, and the rising artist's first original number has steadily accumulated points in video views and streaming since its release in mid-April.
Although yama's style that places emphasis on the intimate collaboration between visuals and music is reminiscent of YOASOBI, the former has gradually been expanding its reach from video to streaming and from streaming to downloads. Like "Yoru ni kakeru" at No. 1 this week, "Haru wo tsugeru" has the potential to continue climbing, depending on how the figures play out in the coming weeks.
