List of artists who reached number one on the Japan Hot 100
This is a list of recording artists who have reached number one on Billboard magazine's Japan Hot 100 chart. Billboard began ranking the Japanese music market on the week ending March 3, 2008.
- 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, 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.
