The RIAJ Digital Track chart (RIAJ有料音楽配信チャート RIAJ Yūryō Ongaku Haishin Chāto?) was a record chart that ranks the best selling digital singles in Japan, with data provided by the Recording Industry Association of Japan from April 2009.[1] The chart measures cellphone downloads (着うたフル Chaku-Uta Full) (not downloads from PCs, or ringtones (着うた Chaku-Uta)). On July 27, 2012, the service that tracked the charts was shut down.


The RIAJ originally started certifying digital downloads in August 2006.[2] At the same time, they began posting a monthly chart called the Reco-kyō Chart (レコ協チャート?) (officially the Yūryō Ongaku Haishin Chart (有料音楽配信チャート?)). This now defunct chart ranked the highest Chaku-uta (ringtone) downloads for the month. The chart was disbanded in March 2009 (the final month's data being February 2009), and was replaced by the identically named weekly Chaku-Uta Full chart.


The chart week runs from Wednesday to Tuesday and updated on every Friday at 11 a.m (JST).[3] The first number-one song on this chart was "It's All Love!" by Kumi Koda and Misono.[4]

At first, the data was sourced from five providers: Dwango, Mora, Mu-Mo, music.jp and Recochoku.[3] On February 19, 2010, RIAJ announced that the data became the more expanded data sourced from 14 providers (new nine providers included the Oricon Me).[5]


Only three non-domestic artists have ever broken the top 10 charts: Michael Jackson's "Thriller" at #7 in June 2009 (directly after his death)[6] and the Backstreet Boys' "Straight Through My Heart" at #4 in September 2009[7] and Lady Gaga feat. Beyoncé's "Telephone" at #5 in April 2010.[8]
