Nintendo's inky shooter has topped the software charts in Japan, helping Wii U become the best-selling console in the country.
Splatoon sold more than 156,000 units during its debut week, more than quadruple its closest competitor, newcomer Hatsune Miku: Project Mirai Deluxe on 3DS.
It helped the Wii U rise to the top of the hardware charts, shifting 15,787 units during the week.
Back in the software Top Ten, The Witcher 3, which fought Splatoon off from the top spot here in the UK, placed third in Japan during its second week on sale.
A pair of new PlayStation Vita releases – Possession Magenta and Cross Ange: Tenshi to Ryu no Rondo tr. in seventh and eighth respectively – plus the continued success of Minecraft on the platform, helped Sony's handheld place second in the hardware rankings.
The only other new software release last week was Downtown Nekketsu Jidaigeki for 3DS, which crept to number nine.
