The singles charts are here: http://entamedata.web.fc2.com/music/hit_top_single.html
Originally, they went back from the present year all the way to 1968 which was when Oricon first started out. However, now they extend even further back to 1950! I believe that before the Oricon charts were launched, at least some of the rankings information was based on music magazines but for now at least, entamedata doesn't have any sources for those early years.
The albums charts are here: http://entamedata.web.fc2.com/music/hit_top_album.html
The albums charts originally went as far back as 1970 but now they stop at 1974. As well, for both sets of charts, there is no longer a column showing how many copies of a single or album were sold.
