E-commerce giant Amazon is launching Friday an e-book reader exclusively designed for Japanese manga aficionados, which is sure to disappoint fans of the comic genre overseas.

The new device's high-resolution display, larger storage capacity, and faster page-turning abilities make the device "the best Kindle that manga fans can get," Jasper Cheung, president of Amazon Japan, said in a statement.

The marketing of an e-book reader with a 6-inch display that exclusively targets Japanese consumers is a key test for whether Amazon can adjust to Japan's unique book market, said Atsushi Matsumoto, a freelance journalist well-versed in the digital content industry.
