Ameiko Kaijitsu has been posted in the previews section over at the Reaper site and on the Paizo site.
She appears in and on the cover of The Brinewall Legacy, a Pathfinder RPG adventure for 1st-level characters, by James Jacobs. This volume of Pathfinder Adventure Path launches the Jade Regent Adventure Path.
Although she appears on the cover, the art was flipped during the layout process. The art I received by Wayne Reynolds for the character design was facing the opposite direction. Such is the publishing biz.
