Famitsu Sales: Week 9, 2021 (Feb 22 - Feb 28)

[PAOerfulone]

06./05. [NSW] Mario Kart 8 Deluxe (Nintendo) {2017.04.28} (¥5.980) - 13.575 / 3.699.547 (+1%)
07./04. [NSW] Animal Crossing: New Horizons # (Nintendo) {2020.03.20} (¥5.980) - 13.332 / 6.668.414 (-3%)

I think that's the first time since Animal Crossing came out that Mario Kart has beaten it head-to-head.
