It seems kind of unusual to be driving out in wide open spaces in one of the vast Tea Field areas in Saitama and see a Logging Area. Lots of fallen trees, large Logs, and big stumps are stacked up here and it just looks out-of-place in this area.
But it doesn't matter to serious GeoCachers. They might not even notice all these Logs and Trees because they are focused on finding the Cache container at the coordinates listed. But, what if the Cache is hidden in one of the log piles ??? 
Then they might notice all the tree stumps, logs, and wood chunks !! 
Merry Christmas and Happy New Year!!!! Good Luck and Happy Hunting!!
