There have been some changes to the reporting style here on the Blog. Please refer to the post here for further information.
It is thanks to the amazing folks over at Oricon that we get to see these charts on a weekly basis, so be sure to head over to their site here and show them lots of love! In addition, all the data you find below is accessible via Oricon right here (Manga) and here (Series). To access the sales data, be sure to click on the “Analytics” accordion and then click “Chart”. This should bring you to the Google chart page that contains the latest available sales data. Many of the titles that you see below have been discussed in the TSUTAYA’s sales chart for the same week, so do have a look at it right here. Some titles that did not make it onto the Top 30 chart were also discussed in the COMIC ZIN’s chart here. Please note that while Oricon tracks sales from a huge number of stores in Japan, the sales data below are not at the fullest since some stores do not participate in Oricon’s daily surveys. For more information about Oricon, please refer to this page.
Without further ado, the full Top 30 is as follows:
