There was a complete set of the AOTC bottle caps with a Geonosis display that was available. Of course, the peddlers on eBay wanted close to $300 for it. It's nice, but not that nice. The bottle caps themselves became pretty hard to sell off, even at $2 a piece U.S.; I paid a decent price to get all mine, including the Clone/Jango chase cap and chase card from a friend in Japan. Haven't seen them since.
There are places like Jlist.com that sell a handful of cool Japanese Star Wars pieces. The actual distributir of SW in Japan is TOMY though. TOMY handles more than just action figures, they had a PLUSH JAWA, a line of LED necklaces, puzzles, mini dioramas, you name it.
