Billboard Japan and Oricon download charts

Unlike other markets, physical music formats in Japan have remained dominant over digital distribution, even into the 21st century. In 2022, physical media accounted for 11% of music industry revenue in the United States; in contrast, it made up 66% in Japan. Although physical media was still dominant, digital figures in Japan were gradually growing. While subscription-based streaming services such as Spotify struggled to pick up like it had elsewhere, the digital download format chaku-uta (ringtones, either a shortened or full-length version of a song) gained traction. The boy band Greeeen, who primarily marketed themselves via chaku-uta, achieved over one million downloads with "Ai Uta" (2007), but only reached number 24 on Oricon's CD-only Singles Chart. The Recording Industry Association of Japan (RIAJ) began tracking digital downloads in August 2005. Chaku-uta went out of relevance in the 2010s, but the song rankings from digital download services still differed from the CD record charts. The top four positions on Oricon's 2017 year-end chart were occupied by the girl idol group AKB48, whereas the ranking of the download service featured Gen Hoshino's "Koi" and Mr. Children's "Hanabi" in top positions. Journalist Sōichirō Matsutani, writing for Bunshun Online, believed that this sales tactic resulted in Oricon's CD-only charts failing to accurately portray which songs were actually receiving the most listens. == History ==

Billboard Japan Billboard Japan introduced download numbers from iTunes into the Japan Hot 100 chart at the end of 2010. In February 2016, they introduced further download services by partnering with GfK Japan, who Musicman reported would provide data for 80% of the download market share. Billboard Japan launched dedicated sub-charts for digital download songs and albums – the Top Download Songs and Albums charts – on October 4, 2017, alongside the Top Streaming Songs chart. Namie Amuro's "Hero" was the inaugural number-one on the download songs chart, and Ariana Grande's The Best was the inaugural number-one album. Oricon Even with the growing popularity of download services, Oricon continued to exclusively publish their CD-only charts. Circa 2008, there was discussion within the company to launch a chaku-uta chart, but such meetings were unfruitful. Oricon CEO Sōkō Koike blamed their lack of a secondary data provider independent from record labels. On November 9, 2016, Oricon launched the Digital Albums Chart, based upon four download services. The inaugural number-one was Fantôme by Hikaru Utada. A year later, they launched the Digital Singles Chart on December 19, 2017, with "Anata", also by Utada, as the first number-one. == Methodology and differences ==

Oricon's digital charts are published weekly and rank the top 50 records in Japan; the Digital Songs Chart also has a daily issue, which ranks the top 20 releases. The Billboard Japan charts are published weekly and rank the top 100 records. Billboard Japan receives data from Gfk Media and NielsenIQ for five download providers – Amazon, iTunes, Mora, , and RecoChoku – whereas Oricon independently collects from seven: those used by Billboard, in addition to OriMusic (their own store) and Music.jp. Since collecting download numbers requires permission from the record label, Billboard Japan calculates an estimate based upon iTunes numbers for labels and artists they are not partnered with, collected by the Los Angeles-based Luminate. At the time of the Digital Albums Chart's establishment, Oricon were in agreement with 35 labels to collect download data. == Year-end number ones ==
