Where is this fact confirmed?

Because it'll take me forever to sift through all the Hal cut scenes of the series to isolate the lines that confirm/discuss it: http://metalgear.wikia.com/wiki/Hal_Emmerich#Etymology

And I want to say there's a scene in MGS4 where Hal is looking up anime on his computer during one of the cutscenes.

EDIT - [url=https://youtu.be/mbRpPqcqRVg]Actually he makes direct note of it here.[/url] He derives inspiration from anime even.
