Some other Utada records/milestones:

Japanese Achievements:

1) She has released 4 million selling singles
2) She has achieved 12 #1s on the Oricon Weekly Singles chart
3) Her album "Distance" (2001) sold well over 3.000.000 during it's first week of release, more than any other album worldwide. In the US the fastest selling album is "No String Attached" by *NSync which sold 2,4 million copies during it's debut week in the USA only. It's worldwide sales during that week must be between 2,5 million - 2,6 million approximately. Thus, Utada's record as the fastest selling studio album worldwide still stands (with a margin of approximately 500,000 copies)
4) Utada's 2007 blockbuster #1 single sold about 651,000 physical copies. Nevertheless, EMI has announced total digital sales of over 8,180,000. Those sales were generated by iTunes and other Japanese music download sites, which have become staggeringly popular nowadays in Japan. Digital single and album sales are way higher than the respective US digital record sales nowadays, even though, the USA is expected to replace Japan as the #1 country in digital sales very soon.
5) Utada has released one 8 million selling digital single, two (almost) 3 million selling ones, two 2 million selling ones, and three more 1 million selling ones (of which one has sold 1,96 million and will soon have surpassed the 2 million mark). Generally, she must be one of the biggest digital selling artist ever.
6) According to Music Station Utada is the 9th best selling artist of all time in Japan. She is also the 4th most successful female artist according to the same source.
7) All of her Japanese albums have debuted at #1 on Oricons Weekly Album Chart with record-breaking sales.

International Achievements:
1) Utada has achieved several #1 and top 10 albums in Asian countries such as Korea, China, Singapore etc. Her album "First Love" has achieved worldwide sales of about 10-11 million copies (most of them sold in Asia).
2) Utada has achieved one #1 single, one #5 and one #24 single on the US Dance/Club Play ("Devil Inside" [2004], "Come back To Me" [2009] and "Exodus '04" [2005] respectively).
3) Her US single "Come Back to Me" (2009) hit #93 on the US Pop Charts. It also received substantial airplay peaking at #69 on the US Pop 100 Airplay and at #39 on the US Rhythmic 40 Airplay.
4) Utada has also achieved minor commercial success in the UK, with her 2005 single "You Make Me Want to Be a Man" hitting #227 on the UK Singles Chart


Utada has also released two albums that have failed to chart on the Oricon Weekly chart under the pseudonym U3, titled "Star" (1993) and "Are Kara 10 Nen Kinen Ban" (2003).
