According to the latest stats from magazine publisher Enterbrain, Nintendo's Wii outsold Sony's PlayStation 3 in Japan by almost 4-to-1.
By February 24, 331,627 Wii units had been sold in the region, compared to 89,131 PlayStation 3's, reports Reuters.
Nintendo's home console has been outselling Sony's machine almost continuously since both became available on the market.
Although Sony's sales are improving – and by no means as poor as Microsoft's Xbox 360 in the region – the Wii continues to prove itself the dominant console.
Nintendo's Super Smash Bros. Brawl became the fastest-selling Wii game to reach one million units in February, doing so in just 11 days, and the game has now sold a total of 1.33 million.
Wii Fit continues to enjoy impressive sales, notching up a further 309,311 units in the first four weeks of the month.
