Amazon's Kindle Paperwhite can hold dozens of books without breaking a sweat, but the company is focusing on comics and art with its newest, region-specific model. Amazon Japan launched the "cartoon" model Kindle Paperwhite, which offers a performance boost over the current Paperwhite as well as eight times more storage, at 32GB.

The extra storage is meant to help the device hold hundreds of manga books at once. Amazon added a few other new features to make it easier for comic-lovers to enjoy their books, including "rapid page turn" which is 33 percent faster than the page-turning effect on the regular Kindles, and a two-page spread layout for viewing pages side-by-side.

The manga model Kindle Paperwhite also has the same 300ppi display of the newest, regular Paperwhite, and it should get up to six weeks of reading time between charges. The Kindle Paperwhite that's available worldwide has 4GB of storage, which is more than enough for holding books for the average reader. But for graphic-heavy titles, more storage is essential.

Amazon Japan has opened up preorders for the device, which costs ¥16,280, or about $157. Unfortunately, the device is currently only available in Japan.
