List of artists who reached number one on the RIAJ Digital Track Chart

This is a list of recording artists who have reached number one on RIAJ's Digital Track Chart chart. RIAJ began ranking full-track cellphone downloads in April 2009. Note that PC downloads (such as those from iTunes) currently are not tabulated.

• All acts are listed alphabetically.
• All acts are Japanese unless indicated otherwise
• Solo artists are alphabetized by last name, groups by group name excluding "A," "An" and "The."
• Each act's total of number one Hot 100 hits is shown after their name.
• All artists who are mentioned in song credits are listed here; this includes one-time pairings of otherwise solo artists and those appearing as "featured" (for example, for "It's All Love!," both Kumi Koda and Misono receive a mention each).
• Artists associated with a group who reached number one, yet have their own solo page in Wikipedia are not listed here, unless they hit number one as a solo artist.
• Artists are listed by their most common musical stage name (for example, Jin Akanishi not Lands, Tsuyoshi Domoto, not Endlicheri Endlicheri/244 Endli-x/Tsuyoshi).
• Artists currently without Wikipedia pages have their corresponding Japanese Wikipedia pages linked. If the artist has a non-Roman script name, this is listed as well.
