The RIAJ Digital Track chart (RIAJ有 料音楽配信チャート) is chart ranks the best selling digital singles in Japan, based on chaku-uta full downloads. It began in April 2009. Prior to this (August 2006-March 2009) the RIAJ released a monthly chaku-uta chart, but this has been discontinued.
The RIAJ has been digitally certifying songs since August 2006, though certified the backlog of songs released prior to this.
Digital sales are much larger than physical sales in Japan right now. Many songs in the last few years have been certified as selling multi-million copies, as opposed to the physical charts which have had very few, if any.
What the hell is this chaku shit?
There are three digital formats in Japan: Chaku-uta (着うた（R）) (ringtones), Chaku-uta Full (着うたフル（R）) (full-length songs downloaded on cellphones) and PC downloads (PC配信). The name is a shortened version of Chakushin Melody (着信メロディー Ringtone (lit. "arrival melody")) and Uta (うた Song). The song downloads are called full-length ringtones since the ringtone service was well established before downloading music on your cellphone was. Chaku-uta Full started in 2004 by KDDI, and spread from there.
Okay then. What's the biggest market?
The Chaku-uta market, though eventually it seems the Chaku-uta Full market will win out. There are so many ringtone downloads that they don't even give out gold certifications, or even platinum certifications. PC downloaded songs never really get beyond the gold certification, and the highest one has ever been certified is double platinum (500k).
What services count for the Chaku-uta Full weekly chart?
Originally only Dwango, Mora, Mu-Mo, music.jp and Recochoku. Other services were added in 2010: Axel Mark, Daiichikosho, Digimerce, Hudson, Konami Digital Entertainment, NTT Communications, Mediado, Music Airport, Oricon Me, Scoop Music and Yamaha Music Media.
Does iTunes count?
Yes and no. iTunes doesn't count for the weekly chart as it's a PC download (not a cellphone download), but it counts to the PC download certifications.
What are the certification thresholds?
There are five main ones: Gold (ゴールド) (100,000), Platinum (プラチナ) (250,000), Double Platinum (ダブル・プラチナ) (500,000), Triple Platinum (トリプル・プラチナ) (750,000) and Million (ミリオン). After million, each song is certified for each subsequent million it sells (2 million, 3 million, etc). Ringtone certifications begin at double platinum.
Where is my favourite Johnny's group?!
Because Johnny's and a couple other record labels don't release their songs for digital download, for whatever fiscal reason. It's like how Sony don't release things on iTunes, since they have their own music download place. They occasionally do (such as Tokio's Sorafune, and Akanishi Jin's Eternal).
Why did this song chart before it was even physically released?
Sometimes things are released digitally earlier than the physical version, or later.
