List of best-selling albums in Japan

Japan is the second-largest music market in the world and the following lists cover the top-selling albums in the country of Japan, based on information provided by the Recording Industry Association of Japan and Oricon Inc.

History
In the history of the Oricon weekly albums chart, which started in January 1970, only 280 out of all of the charting albums have sold more than one million copies, a feat mostly achieved by domestic acts.

This is a list of the top-selling albums in Japan, based on data compiled by Oricon. Prior to January 1987, the domestic albums chart was separated into LPs (created in 1970), cassette tapes (introduced in 1974) and compact discs (launched in 1985), until their unification, which remains the current form. It is worth noting that Oricon only takes into consideration physical sales for its charts, meaning that digital purchases are excluded. The best-selling album is First Love (1999) by non-binary solo artist Hikaru Utada, which sold over 7.5 million copies by the end of that year. Ryuichi Kawamura's Love (1997) topped the album chart with sales of 1,021,000 copies, making him the only male solo artist to have an album sell over one million copies in its first week in Oricon history. Love went on to sell 2,788,000 copies, and holds the record as the best-selling male solo album of all time. Whereas, Mr. Children's Atomic Heart (1994), still remains its position as the top-selling original studio album by a male band.
