Billboard sister organizations Billboard Radio China and Billboard Japan will launch a new Billboard Japan Hot 100 Chart Countdown segment on Billboard Radio China FM.
Beginning the second week of January 2019, Chinese audiences will now hear the latest Billboard Japan Hot 100 Weekly Top 10 Song Highlights and get to know what is trending in J-Pop.
The Billboard Japan Hot 100 currently combines physical and digital sales, radio airplay, streaming, Twitter mentions, YouTube and GYAO! video views and Gracenote look-ups, which counts how many times a CD is ripped onto a computer. In order to reflect the ever-changing music landscape and the different ways music is consumed, starting December 2018, the chart introduced the karaoke metric, as more and more users use karaoke as a means to "interact" with music.
