It looks like it's not that simple. This appears to be a model that isn't available in the US or outside Japan, at least not under the name and model number it has. The American Toshiba site doesn't even allow you to contact anyone, just select from dropdown menus, and if your model isn't listed there in the dropdown, you're out of luck.
If I go in through the Toshiba Japan site, I eventually reach a page that tells me there's no assistance available other than in Japanese.
