For those who are curious, the following list is a compilation of the 27 Japanese G-films released in the U.S. to date in the order of their American release, exactly as Western audiences saw them over a 49-year period. The original American theatrical titles are listed for nostalgic accuracy, and when different from the current video title, they are placed in brackets. The year of their American release is also listed, as is the American distributor. The films marked with [DTV] after their respective distributor indicate that they were sold direct to television rather than ever playing on the big screen, and those marked with [DV] indicate they went direct to home video rather than the theaters.
Of course, this section will be continually updated as more G-films are released in the U.S.
