Category:Number 1 Releases
Releases in this category are ones that have become #1 in the charts. Charts will most likely mean Japanese Oricon charts, though it could be a reference to a different chart. The Gaon category shows a comprehensive list of all the releases (albums/mini-albums/singles/digital downloads) that become #1 on digital or physical charts.
Note: No releases should point to this category. They should point to one of the sub-categories.
