RIAJ Digital Track Chart

The {{Nihongo|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.{{cite web|url=http://www.riaj.or.jp/release/2009/pr090410.html|title=「着うたフル（R）」有料音楽配信チャート本日より毎週金曜日に公表開始|publisher=RIAJ|date=April 10, 2009|access-date=May 12, 2010|language=ja}} 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.

History

The RIAJ originally started certifying digital downloads in August 2006.{{Cite web|url=http://www.riaj.or.jp/data/others/chart/w060920.html|title = 一般社団法人日本レコード協会}} At the same time, they began posting a monthly chart called the {{Nihongo|Reco-kyō Chart|レコ協チャート}} (officially the {{Nihongo|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.

Methodology

The chart week runs from Wednesday to Tuesday and updated on every Friday at 11 a.m (JST).{{Cite web|url=http://www.riaj.or.jp/data/others/weekly_chart/index.html|title=一般社団法人日本レコード協会}} The first number-one song on this chart was "It's All Love!" by Kumi Koda and Misono.{{cite web |url=http://satsuki.musicdb.gr.jp/all_info/ranking_weekly/WeeklyRankingAction.do?term=2009f&weeklyCd=20090407&rankKbn=50 |title=一般社団法人日本レコード協会｜各種統計 |access-date=2011-02-12 |url-status=dead |archive-url=https://web.archive.org/web/20140821112959/http://satsuki.musicdb.gr.jp/all_info/ranking_weekly/WeeklyRankingAction.do?term=2009f&weeklyCd=20090407&rankKbn=50 |archive-date=2014-08-21 }}
