Nintendo's Switch console has now surpassed 1.5 million units sold in Japan alone 26 weeks after it was first launched.
This is according to sales figures from retail tracker MediaCreate, via 2ch and reported by Kotaku. In comparison, Sony's PlayStation 4 console sold just 665,000 units in its first 26 weeks of sale.
Nintendo's own most recent sales figures state that the Switch had sold 4.7 million units worldwide as of June 30th 2017. MediaCreate's figures suggest that an additional 500,000 units have been sold in Japan so far since that time.
Sales in Japan also appear to have leapt up following the launch of first-party exclusive Splatoon 2. Figures for the week following the game's release see Switch unit sales jump from 31,906 to a post-launch peak of 98,999.
Nintendo currently plans on selling over 10 million Switch consoles by the end of its FY18. Reports indicate it is targeting production of 18 million units in this time.
