The WiFi and 3G/4G-compatible tablets will link to Sony's streaming music and video store Qriocity, and its e-book offering Reader Store.
They will also work as remote controls for Sony AV devices, initially for the Bravia TV range.
Kunimasa Suzuki, deputy president of Sony's consumer products and services group, said: "Sony Tablet delivers an entertainment experience where users can enjoy cloud-based service on-the-go at any time.

Another company making its debut in the tablet market is Taiwanese smartphone manufacturer HTC.
The HTC Flyer runs Google Android and goes on sale in the UK on 9 May.
