Though I've included a Treasure Hunt page, there are in fact no Japanese carded Treasure Hunts. The Treasure Hunts that were available here were on the standard English card with just a Japanese language sticker on the back(the way all Hotwheels are sold in Japan now). As I only collect Japanese carded Hotwheels I haven't collected any of the Treasure Hunts, but in case anyone is interested, I'm including a list of the Treasure Hunts as they appeared in the 1999 and 2000 catalogs.
