YouTube videos that dominated the charts in Japan over the last 7 days.
The weekly ranking measures consistency over time - every hour spent in the top charts counts. A single-day viral spike carries far less weight than a video that dominates for several consecutive days.
How fast this chart renews itself
Over the last 7 days, the ranking in Japan replaced an average of 80% of its entries every day, moving between 74% and 86% depending on the day. That is a chart that is almost entirely rewritten from one day to the next, where a video has a single day to be seen. This figure comes from comparing our own daily snapshots: YouTube publishes the ranking of the moment, never how much of it survived since yesterday.
The chart carries about 49 entries a day, filled by 49 distinct channels, so almost every slot belongs to a different publisher. Concentration only appears when one channel places several videos at once, which is exactly what the ranking above lets you check.
The most resistant video of the week held on for 3 consecutive days: Nintendo Direct 2026.9.9. Survival time is a far better measure of a video's strength than the position it opened at, because it is the only one a launch budget cannot buy.
The sharpest climb belonged to ๆฅๅๅ46ใ้ขจใซใญใณใขใฏใปใคใMUSIC VIDEO, up 11 places in a single day. A jump of that size in twenty-four hours almost always signals an audience arriving from outside YouTube rather than gradual discovery.
