I remember hearing the Fuji film company wanted to sponsor the Mt Fuji ride in Japan, but that didn't sit well with Kodak, who is the official film of WDW. They supposedly threatened to pull out out of their deal so negotiations with Fuji never came to frutation.
No truth to this at all.
Absolutely none. Zero. Zilch. Nada.
Just a dumb CM/Internet/Urban myth.
Mt. Fuji is a national landmark of Japan. Not a symbol of a photo company. I once was at a Disney media party with a Kodak rep who laughed his a$$ off after hearing what's on the www.
