The Switch is close to surpassing the total lifetime sales of the Wii U in Japan after less than a year on sale, according to Famitsu.
Last week, Nintendo's console sold 230,000 units in Japan, bringing its total in that region to 2,988,399 units. It launched on March 3rd this year.
At the last count, the Wii U had sold around 3.32 million consoles in its homeland. It launched on December 8th, 2012 - just over five years ago.
If Switch continues to sell at its current rate - and there's little reason to think it shouldn't - then it could potentially overtake its predecessor's install base in time for the start of 2018.
