In 2007, Japan had the second largest music market in the world.[1] In 1962, Tokushin music reports was founded and became the leading provider of music sales in Japan. However their reports and charts are only available to industry insiders and are not available to the general public. In 1968 Original Confidence was established and began providing music charts to the general public with data collected from various retailers throughout Japan.
This is the list of the best-selling singles, based on the data by Oricon. It does not include singles that were released before 1968, and is only from data collected from Oricon's retail partners and not the record companies.
