If you were planning to import a PS Vita TV device from Japan, you’ll be sad to know that the device will be region locked. The device can only be used with a Japanese PSN account, so importers should wait for a Western release to make the most of the device. A post of NeoGAF says the device doesn’t work with non-Japanese accounts.
“Initial signs are not good” says NeoGAF user desbang – “it will only let me log in with my Japanese account”. Using the device with a US and New Zealand account simply returns a “This service is not available in your region” message, rendering the system useless to non-Japanese accounts.
The user also notes that the system comes with a list of 60 games which are not compatible – presumably titles that require PS Vita specific features like the rear touch pad.
