Bought a ton of these on my visits to Japan. They had a series of Mario coins, some Monster Hunter and Pokemon ones. I bought the entire series of Danboard ones. Out here in NSW there is a few places to get them, Million Life which does claw machines too. Coco amusements on George St has some, and Gacha Gacha has locations at Hurstville, Centrepoint Westfield and regent place. There is also a Popmart opening in World Square which I think do Gacha.
