You will be looking for an official geocache small container. There are about 3 or 4 places you can park in the area, but I recommend the sports center parking lot for a long but enjoyable stroll to the GZ. Be very wary of muggles due to this place being a hub for runners, joggers, athletes and such.
FTF gets to be FTF a cache of 2013 Okinawa and an activated (sorry) Mayan Calendar GC spinner because hey, it's the end of the world right? No? Hmm.
Congratulations . . . aaaand my sincerest apologies to wandering gaijins for my misleading FTF statement. I promise it won't happen again.
