In Japan, record charts for paid download songs and albums are published separately by competitors Billboard Japan and Oricon. Although Billboard Japan has factored downloads since 2010, Oricon were the first to launch a download-only chart in November 2016, with the Digital Albums Chart; a year later, they opened the accompanying Digital Singles (Single Track) Chart. Also that year, Billboard Japan launched the Top Download Songs and Top Download Albums charts simultaneously. Both publications share several parts of their methodology, and the year-end number ones have been the same for both since their inceptions.
