I’m about to watch the trilogy with my Japanese buddy who has never seen any of the films.

I got my hands on a copy of Harmy’s version, and it has Japanese audio, but he would prefer Japanese subtitles. When I checked out the Japanese sub file, there was very little text in there. Doesn’t look like the complete movie. Could anyone help me find a complete Japanese sub file for A New Hope? Or even the whole trilogy? (Don’t know if this issue pervades through the other two films or not.)
