Methodology
From the chart's inception in 2008, to December 2010, the chart combined CD single sales data from SoundScan Japan, tracking sales at physical stores across Japan, and radio airplay figures from Japan's then 32 AM and FM radio stations sourced from the Japanese company Plantech. In December 2010, the chart expanded to include sales from online stores, as well as sales from iTunes Japan. From December 2013, Billboard incorporated more digital music stores into the chart. Billboard also added two additional factors: tweets relating to songs from Twitter data collected by NTT DATA, as well as data sourced from Gracenote on the number of times a CDs has been registered as being inserted into a computer. In May 2015, the chart began to include both on-demand streams and YouTube views. Finally, in November 2018, the chart began to include karaoke plays in its formula. In December 2022, the Twitter and Gracenote metrics were removed from the chart.From December 7, 2016, onwards, Billboard Japan teamed up with GfK Japan to distribute digital sales of each track on the Hot 100 chart to the public. The companies will distribute the sales from over 3,900 digital stores nationwide, alongside streaming services with Apple Music, Awa and Line Music, which will commence in 2017 and will be recognized as points. In June 2025, Billboard Japan introduced the recurrent rule for Japan Hot 100, alongside the Hot Albums, applying for songs that chart more than 52 weeks. It effected on the chart week of June 4, 2025.
