Amazon is on the cusp of launching the complete Kindle line in Japan, so it's only right that the online retailer fine-tune its firmware for local reading habits. A new version 5.3.0 update for the Kindle Paperwhite puts much of that focus on Manga, introducing options to fit the stylized comics to the screen as well as tweak their page refresh interval separately from that of plain old text. Wider efforts to improve font rendering touch on Japanese characters in the process. Even if we're a little rusty with our hiragana, there's still some usability tweaks in store: settings are accessible directly from the menu, readers can purge their home screens of recommended content and sample books now sync their position relative to the full title. The bookworms among us that are too impatient to wait for an automatic update to 5.3.0 can hit the source link for the full skinny and a fast-track installation through USB.
