Sony has today announced a new Wi-Fi only version of its Xperia Z Ultra that will go on sale in Japan later this week, priced at ¥51,800 ($495). By removing the device’s cellular radio, the Japanese company has transformed it from a super-sized smartphone into a compact tablet, but the rest of its internals remain untouched.

So, in addition to its 6.4-inch 1080p display, the Xperia Z Ultra packs a 2.2GHz Snapdragon 800 processor, 2GB of RAM, 32GB of internal storage, and a microSD card slot. It also has an 8-megapixel rear-facing camera that’s capable of shooting 1080p video, and a 2.2-megapixel front-facing camera.

Like the slightly smaller Xperia Z1, the Xpera Z Ultra is dust- and water-resistant, with IP58 certification. It ships with Android 4.3 Jelly Bean, but Sony is planning to update it to Android 4.4 KitKat soon.

The new Wi-Fi only model will be exclusive to Japan for now, but should it sell well — and Sony devices usually do over there — then we could see it expanding to other markets, too. If you happen to live in Japan, you can pick one up on January 24.
