A couple of things to note about Oricon sales chart would be that although the organisation covers a wide range of stores in Japan, it does not include all stores such as COMIC ZIN you see down below. As such, sales from COMIC ZIN would not be counted on Oricon’s weekly Manga charts. Other versions of a product such as store exclusive packages may be counted if they are reported, if they aren’t reported then they will miss out on the chart. This includes special pre-order events that will also miss out on Oricon’s weekly charts. Finally, the most important thing is that Oricon only tracks physical copies sold while it is unclear if TSUTAYA and COMIC ZIN would to count digital sales in their weekly charts. Do take note of all of these when consuming the weekly charts below.
