Nikon stock ticker, financial info missing for the US market – what’s going on here?

I am trying to trace down Nikon’s stock market ticker and financial data to get some corporate information. I guess their stock in not traded in the US. Is this possible? See here for yourself – traded everywhere around the world, except the US. Canon, on the other site, is traded on the NYSE under the ticker CAJ. I guess I have to look into the Japanese stock exchange.

Can someone clarify this for me?
