This geocaching experience is all about the view and small pavillions with benches on the walking bridge, if you come from the direction of the San-A. It is a well maintained walking path with small apartments/town houses adjacent too it. So there are usually some muggles in the area but not too bad, especially at night. The path is wheelchair accessible, however, they would need to take a longer route around buildings if starting at the San-A.
My wife wants me to warn everybody to stay safe, thinking maybe a habu might move into the area (Very short grass, light colored man-made trail frequented by people, not too much of a concern, but then again....) and also, worried that you might fall from the bridge (Decently high walls that unless you are over 20' tall or climbing on them, shouldn't happen but...) or from the steep hill slope that is a good distance from the cache itself.
The cache itself is about the size of a deck of cards and a silver/grey color. FTF gets 100 yen and a first to find coin. Also inside is some sea glass pieces.
Congratulations to Orion67 for the FTF.
