The cache at Western World was inside of a fake rock, and I had a little trouble finding it, since the entire area was covered in similar rocks.
My third stop was at the Kurishiki Dam for a seven part multi-cache. I found part one, entered the coordinates for part two, and never found it. I had to be right on top of it, since my GPS zeroed out, and I found the benchmark that was mentioned in the hint. I simply coudn't come up with the cache. It's been a while since it was last found, so perhaps recent maintenance workers muggled it. I still had a good time, and the scenery was great. Here's a few pictures:
