Recently I was walking on a path near my hotel when I noticed a
long row of tin soldiers standing in the trees along the path.
(They're not really made of tin, but they ARE made of metal. Okay,
they're not really soldiers either, but they ARE in my
imagination.) There are hundreds of them all in a row and they are
dressed in brown uniforms with black helmets. They haven't received
new uniforms in a very long time and some of them are looking very
threadbare.
One of these soldiers near the above coordinates is keeping a
micro-cache under his helmet. His helmet can be removed easily. If
you are having difficulty removing the helmet, then you haven't
found the correct soldier yet. The encrypted hint below will
significantly narrow your search. This is a very small cache and
contains only a bit of "waterproof" paper for a log. There is no
room for trade items, and you must bring your own pen. A ballpoint
pen is best for writing on this paper.
The cache is within 400 ft. of Nakafuto (P11) station on the
Nanko Port Town Line. Also within 10 feet of a paved bike path
which is frequented by muggles, so some stealth is required.
