If you want to find it, then you could DRILL, BABY! DRILL (or dig)!! FTF gets a small green bison tube container (with log) to plant!

No time to dig/drill? GeoChecker.com.
Updated 6Nov2013: Ok gang. I've increased the terrain rating a full star due to the heavy vegetation and additional walking required. Also changed the hint. It was either too hard to crack or dumb. Either way, had to go. So, now that you've solved for zero and are ready to go log it, you will notice 2 signs in Japanese on your walk to the cache. The first is yellow and has a low chain. Big Dave73 translated it for me and all it says is "no cars past this point". That sign is new and hence the aforementioned additional walking. The second sign you'll see is red and white. Bill71's wife translated it a while back, but it's just a list of rules for fishermen (hint hint) - like bag limits and off-limit species, etc. Contents as of today are: the original log, Pirate Booty Skull and Map Dubloon Geocoin and a pink jump rope. Happy hunting gang!
