Design - 1 - Iconic image icon

I've been trying to figure out the most iconic landmark or attraction in Osaka Japan. The easiest way to figure this out was to compare what was listed highest on their sight seeing points and what came up most frequently on Google.

Osaka Castle is everywhere, and yes the results are almost the same if you add "Japan" afterwards.This is helpful though because it seems like more people would recognize Osaka Castle as the landmark of interest; If I use it in my logo for the letterhead project it'll make the whole design more recognizable as a piece for this specific location.
