This "hiding Japanese options when player is not set to Japan" phenomenon occurs fairly frequently on Warner discs. It's not entirely clear to me what the reasoning behind this is.

Tools like eac3to or BDInfo that analyze Blu-ray disc contents will always detect these if they are present, so following the Unofficial Blu-ray Audio and Video Specifications Thread @ AVS is a good place to find new titles with these "hidden" tracks by looking at the posted disc reports.
