Just like the Xperia Z phone, the tablet of the same name is claimed to be waterproof - making it "immune to accidental spills and splashes" - and also dust proof.
The tablet has a 10.1-inch HD display (1920x1200) with high brightness and high definition video WUXGA technology, along with Sony's Mobile Bravia Engine 2 for boosting the image content and contrasts.
Running Android 4.1 Jelly Bean, the Xperia Z tablet is powered by a 1.5Ghz quad-core processor and has an 8.1 million pixel camera on the rear, equipped with a CMOS sensor Exmor R for the first time in a Sony tablet.
Sony says that the camera performs better in low-light conditions, and automatically adjusts to the optimal settings.
This all comes in a tablet that weighs 495g, but is just 6.9 millimetres thick - beating the iPad Mini's 7.2mm, believed to be the previous thinnest tablet on the commercial market.
The Xperia Z tablet supports Near Field Communications (NFC), enabling one-touch wireless streaming of photos and music, and also Long Term Evolution, or 4G internet, as well as WiFi.
"Xperia Tablet Z sets new standards in entertainment by matching premium specifications and Sony technology with cross-device connectivity and a consistent user-experience," said Sony Mobile's Kaz Tajima.
"Xperia Tablet Z reinforces our intention to be a leading player in the premium Android device market, by building on the principles established by Xperia Z and perfectly optimising them for the tablet form factor."
Sony says that it has fitted the slate with "S-Force Front Surround 3D", a new technology that gives the user 'virtual surround sound' from the speakers.
Available in either black, white or red, the Xperia Z will roll out globally in the second quarter of 2013.
Official pricing has not yet been announced, but AllThingsD says that the 16 gigabyte WiFi version will cost $499 (£329) in the US, and the 32GB model will cost $599.
The Xperia Z tablet will launch on Android 4.1, but upgrade to 4.2 afterwards.
